An ultimate and comprehensive guide to rapid prototyping

Rapid Prototyping: Everything You Need to Know Rapid prototyping is a relatively new term. However, it has gained popularity in a short time. Industries around the world tend to use rapid prototyping. After all, it offers a number of advantages such as lower costs, error-free production, etc.

The method incorporates a number of manufacturing technologies. The most common of these technologies is additive manufacturing. Nonetheless, there are other technologies that manufacturers use to RP include molding, extruding, casting, and high-speed machining.

So, in this blog post, we will talk about the rapid prototyping, its types, and its advantages.

Introduction to Rapid-Prototyping You might have heard the term prototyping in the software field. They use it to create software in an effective and efficient manner. The same rule of prototyping applies in other fields as well.

In the simplest form, we can define rapid pcb prototyping as creating prototypes efficiently. Engineers use these prototypes to test the validity of their product design. Moreover, they are able to see how the final product would look and function.

A more formal definition is: Prototype is a preliminary version of an end-product. It makes it possible to evaluate the design, analyze its working, and test its technology. This results in a product that has the specification that would work in the real-world system.

There is no denying the importance of prototypes in designing the product. In addition, it plays a vital role in the overall development cycle of the product. The good thing about rapid-prototyping is that you can use it at any stage of the product development cycle.

Moreover, you can use it for a certain component or a sub-component of the product. The versatility in terms of production makes RP an excellent choice. What more is that you can make as many changes to the prototype as you like.

The endless iterations are not expensive especially when you compare them with the rework you might have to do in case of design error with the entire product batch.

Rapid-Prototyping: Different Techniques Below, we have listed different types of Rapid prototyping.

Vat Photopolymerization or Stereolithography Vat photopolymerization is an inexpensive, yet efficient technique. Being the first fruitful marketable 3D printing technique, it became very popular in a short time. The technique uses a photosensitive liquid to make the prototype. The ultra-violet light monitored by a computer solidifies this liquid layer by layer to achieve the respective results.

Selective Laser Sintering - (SLS) SLS is an effective technique for both plastic and metal prototyping. It uses a powder bed to create one layer of the prototype at one time. To sinter and heat the powder material, SLS uses a high-power laser. Although, it can manipulate two different materials, it lacks the robustness of the SLA.

The prototypes created using SLS are not steady. Furthermore, most products require secondary work to achieve the surface of a finished product.

Fused Deposition Modeling Another inexpensive rapid prototyping technique is fused deposition. You will find this technique part of many non-industrial 3D printers. The procedure requires a spool of thermoplastic filament. It melts the material inside the nozzle barrel of the printer.

Now, the computer deposition program lays down the melted material layer by layer in accordance with the requirements. Initially, the fused deposition modeling offered low-quality and weak products. However, technological advancement has improved the entire process.

It still is affordable, yet the quality of the prototype has improved tremendously.

Selective Laser Melting If the prototype you require is complex and should be highly durable, the SLM prototyping technique is your best shot. Industries like automotive, medical, defense and aerospace frequently use SLM.

The procedure makes use of fine metal powder. It melts the powder layer by layer, thus gradually upbuilding up the prototype. Manufacturers also use this technique to build robust and strong components. For melting the power, it uses either an electron beam or high-powered lasers.

Cobalt Chrome alloys, aluminum, titanium, and stainless steel are the common Selective Laser Melting materials.

Sheet Lamination Unlike the SLS and SLM, Laminated Object Manufacturing lack the rigidness. There is no need for specially controlled conditions. The less sophisticated technique uses several laminates. These series of laminates are always thin. It then uses laser beams to cut these laminate piles to produce the CAD design.

To build the part, each layer is fused on top of the preceding one. The process goes on until the desired shape is achieved.

Binder Jetting Binder jetting offers the facility of printing several parts at the same time. It does offer mass production; however, the quality of the prototype is not very strong. The technique uses a powder bed. To bind the powder particles together, it sprays droplets of the liquid via nozzles.

These liquid droplets are micro-fine. This process is repeated for every layer of the part. Moreover, it is important to compact a layer using a roller, before starting with the next layer of the powder.

Doing this solidifies the entire process. To further enhance the robustness of the product, it is cured in an oven. This curing helps to burn off the binding agent. At the same time, it helps in powder fusing in just the right coherent parts.

Digital light processing Digital light processing uses the same mechanism as that of the SLA. However, it does not require an extremely sophisticated method for the cure of polymerization of resins. It uses an orthodox light source to cure the resins.

Even though it is cheaper and faster in comparison to the SLA, the technique does require a post building curing. In addition, there is a need for support structures.

Prototype in Product Design It is possible to category prototypes. However, this greatly depends upon the accuracy that is required by the consumer. In formal words, you can categorize prototypes based on fidelity.

Fidelity Types Low Fidelity Prototype These types of prototypes do not look like the final product. They may vary to a certain degree. The difference depends upon what the product designer wants to achieve from the prototype.

Low Fidelity The low fidelity products are extremely simple. It is possible to produce them in a short period. The basic idea is to test the broader concepts, for instance, cardboard mock-ups or paper sketches.

High Fidelity The high-fidelity products are extremely similar to that of the final product. They not only look like the final product but also offer most of its functionality.

Why Rapid Prototyping is Important? For a company to stay afloat in the modern-day, fast-moving consumer market, it needs to be innovative. Not only this, but the company also needs up to come up with better, advance, and sophisticated products fast to ensure competitiveness.

Since technology innovation and faster product development plays a vital role in the company's success, therefore, the rapid prototyping becomes an important part of the development cycle of the product.

With rapid prototyping, it is possible to achieve the following.

Prototyping makes it possible to create newer products efficiently. It tends to speed up the entire product development cycle. It is possible for the engineers to determine whether their product idea will work or not well before stepping into the production phase. With RP, you can actually validate your product design idea.

It also offers the final stage product verification against the business objectives and the technical requirement.

With prototyping, the end-users, customers, clients can give feedback in real-time as they would have a tangible product to work with.

Take Rapid Prototyping aids technology innovation in every possible way. It lets developers and engineers validate the product idea. In addition, it lets you find any fault in the product design, well before the production phase.

With rapid prototyping, you can actually transform your idea into something tangible. You can present the idea to investors with more confidence and increase the chances of landing them.

All USB cables for your smartphone and computer

More and more smartphones are using USB cables to charge or to transfer data. You can buy such USB cables from pcb assembly. You get the choice between USB-C cables, micro USB cables and more. We explain a few things for you, while our handy filter function guides you to the cables you need.

What is a USB-C cable? The USB-C cable is a special cable with a USB connection and is widely used with smartphones. You use these cables to charge your smartphone via a USB port or to transfer data such as photos and videos to your computer, or vice versa. USB-C ports are also increasingly being used in laptops , external hard drives or digital accessories.

These USB cables have a fast transfer rate that can reach up to 10 Gbit per second, depending on the chosen USB-C cable. An additional advantage of these cables is that they are provided with a reversible connector so that you can never plug them in incorrectly. The plug of this USB-C cable is slightly thicker than the micro-B connectors.

What is a micro USB cable? A micro USB cable is a special cable for micro B plugs. You will find such micro-B plugs in power banks , but also in e-readers and video cards . In addition, smartphones are often equipped with such a port, so you can charge them via the micro USB cable. However, do not confuse the micro USB cable with the mini USB cable that is suitable for B plugs, as you will find mainly on printers and external hard drives. In general, micro USB cables are mainly used with smaller devices where space is limited, such as smaller smartphones, power banks (to leave maximum space for the rechargeable battery) or gadgets such as portable fans. Click here to visit Cable and Wire Harness Assembly 

How long can USB cables be?

It is possible to connect different USB cables together and extend them systematically. However, a maximum limit also applies. If the signals take too long to connect one device to another, the devices are no longer in constant contact with each other and 'forget' that they are connected. This limit is five meters for a 2.0 USB cable, while it is only three meters for a 3.0 USB cable. Would you like to extend your USB cables anyway? Then you must use an active extension cable in which the signal is continuously repeated, so that the devices still remain in contact. In practice, it is possible to extend classic USB cables to about thirty meters via such active USB cables.

Be aware that such long USB cables have a number of drawbacks. The signal takes a very long time, so you cannot stream live, for example. Transferring sound or data is virtually impossible. Also, the USB cable will transfer the information much slower.

How do I use a USB cable on my PC? You plug the USB cable into the USB port of your computer. Then connect the other end of the USB cable to another device, such as a keyboard, cell phone, or even another computer. You may still need to install software, for example if your BIOS does not have USB Keyboard Support. If your PC does not have enough USB ports, you can place a USB hub on a single port and then connect the USB cable.

Circuit boards: so important, but so undervalued

Circuit boards are literally the basis of electronic products and systems. They connect and "wire" dozens, hundreds, and even thousands of active and passive components with tiny islands and thin tracks, while also providing physical support, mounting tabs, connectivity options, and more. Printed circuit boards are often referred to as PCBs or PC boards and a few years ago the IPC, a major organization that sets standards (formerly the Institute for Interconnecting and Packaging Electronic Circuits), tried to call them 'printed wiring boards' or PWBs, but they never succeeded.

We don't need to tell our readers how important the role of printed circuit boards is and how versatile and versatile they are. But in many conversations they are casually seen as an insignificant, if essential, passive part, but that is a simplified misconception.

The interesting history of the circuit board

PCB board assembly have undergone an interesting development. When they were first used some 50 years ago, they were seen by many designers as a necessary evil. They replaced the use of point-to-point wiring and manual soldering, a technique that could no longer meet the demand for products such as color televisions, with their 100+ vacuum tubes. Nevertheless, a major TV retailer at the time prided themselves on the fact that their televisions were handcrafted by craftsmen, rather than by means of an anonymous printed circuit board. We all know what's left of that marketing story.

The first printed circuit boards were single-sided and made of phenol or bakelite, instead of our modern fiberglass-epoxy composite. The holes for the components and wires were punched instead of drilled and they were still hand soldered (Figure 1). The track width varied from 3 to 6 millimeters (mm).

Simple, one-sided 'through-hole' printed circuit boards like this one were made from phenol and were the first widely used versions of printed circuit boards.

The reliability of these youthful printed circuit boards was marginal due to coating delamination, tolerance issues and soldering inconsistencies. But as they say, failure was not an option, as using printed circuit boards was the only viable method to handle the large numbers of components, ICs, smaller components and more pins. In addition, they were able to provide surface mount components with sufficient support. The current circuit boards have been improved many times over in terms of performance and capabilities compared to those first circuit boards.

Interestingly, single-sided phenolic boards are still used in some consumer devices with almost all components. Wire jumpers inserted at the top allow a very inexpensive, single-sided card to be used

Figure 2: This 2010 microwave oven phenolic circuit board contains the power supply (low and high voltage), transformer, switch components, and much of the rest of the circuitry. Pay particular attention to the use of jumpers on the top that allow for a low-cost single-sided circuit board. 

The multitasking precision of a printed circuit board

Despite the casual way we often talk about printed circuit boards, today's copies are very precisely designed precision parts. So much is expected of them, much more than just component carrier and connection platform. A number of tasks are:

They conduct current through the exposed layers if it is a simple two-sided printed circuit board.

In multi-layer maps, such as the commonly used four-layer printed circuit board, one inner layer provides power for one or more busbars and the other inner layer provides ground functions. If necessary, these layers are connected using conductive vias (short for 'vertical interconnect access' and written in lower case).

The copper around or near a hot component acts as a heat sink or as a thermal conductor to conduct heat away to a discrete drain.

The PCB copper can be configured as an RF transmission line, filter, isolator or circulator using stripline or microstrip topologies.

The printed circuit board can also be designed as an antenna, often in multi-band format, rather than a single band antenna.

Passive RF components, such as capacitors and coils, can also be constructed using suitable copper cartridges.

Accurately dimensioned tracks can act as low value (several milliohm) resistors to measure current through the IR drop across the track.

The copper can also serve as a protective ring around sensitive, low-level analog sensor inputs to op amps.

Also, the copper of the PCB can act as an EMC shield to prevent incoming RF from affecting the circuits and to attenuate emissions from the PCB.

The plug-in connector for both solid and flexible pins that terminate individual wires in a cable harness.

And if that were not enough, we can add a new role to the list: act as a socket for an IDC ribbon cable connector (insulation displacement connector) from Würth Elektronik . Instead of the standard IDC connectors, one male with pin contacts (pins) and another with female contacts, the Würth uses the PCB as a partner for the male IDC.

Note that this is not the first time wires have been connected directly to a circuit board. Individual solid or flexible pins have been pushed through metalized holes in a printed circuit board for years. But these pins cannot be removed without damaging the pin and the PCB, so they are a one-time use only. In contrast,  Würth 's REDFIT IDC SKEDD connectors can be inserted and removed up to ten times at specified hole size and coating, up to 25 times at lower tolerances.

Image 3: Thanks to the REDFIT IDC SKEDD connectors from Würth, the IDC connector no longer needs a male (s) IDC and flat cable. This saves costs, simplifies the bill of materials and reduces the number of wire-connector transitions and thus potential problems. 

What does the future of the everyday and underappreciated PCB look like? It seems that the widely used FR-4 epoxy glass substrate does not remain as dominant as it is today. The inherent characteristics of this technology does not meet designs to the stringent requirements of multi-gigahertz (GHz), wherein subtle electrical and material factors such as dielectric constant (e r ), loss factor (tδ), moisture absorption, etc. are of crucial importance. These must not only meet the needs of GHz designs, but also have very low temperature coefficients, or tempco's. Something FR-4 doesn't have. In addition, the mechanical and dimensional tempco's become even more important as even minute shifts affect electronic performance at these frequencies.

The next time someone says the circuit board is nothing special, don't fall for that mindset or misconception. The success of a project depends as much on the PCB as on other components. The ability to maximize features, produce a multi-layer card with incredibly rigorous specifications, place components and solder well, directly impacts base performance, failure / reject rate, and field reliability.

PROCESS OF PRINTED CIRCUIT BOARD ASSEMBLY

Printed circuit board assembly, otherwise called PCBA, is the way toward patching or assembly of electronic segments to a PCB or printed circuit board. A circuit board preceding assembly of electronic segments is known as PCB. When electronic segments are bound, the board is called Printed Circuit Assembly (PCA) or Printed Circuit Board Assembly (PCBA). Diverse Manual and Automatic PCBA Tools are utilized in this procedure.

It must be noticed that assembly of a circuit board is not quite the same as assembling a circuit board. Assembling printed circuit sheets include a few procedures including PCB planning and making PCB model. When a PCB is prepared, electronic parts should be fastened onto it before it very well may be utilized in any electronic gear or device. This assembly of electronic segments relies upon sort of circuit board, kind of electronic segments and motivation behind the circuit board.

Things Needed for Printed Circuit Board Assembly Following hardware parts and consumables are required for Printed Circuit Board assembly –

Printed Circuit Board Electronic parts Soldering materials including bind wire, patch glue, weld bar, patch preforms (contingent upon the kind of fastening to be finished) Soldering motion Soldering gear including patching station, wave welding machine, SMT hardware, and review and testing hardware and so forth.

Top 10 Tips To Ensure PCB Assembly Success

At the outset, it is important to differentiate between Printed Circuit Board Manufacturing and Printed Circuit Board Assembly. While the former deals with fabrication of the board, the latter deals with assembling the components on the circuit board thus manufactured. Reference 

Not just in PCB Manufacturing, when it comes to PCB Assembly as well, you need to ensure that you get a solution that is both high quality as well as cost-effective. This is made possible if you pay the process due attention and treat the PCB Assembler as a consultant who can offer effective suggestions not just in terms of assembly, but also on aspects such as design of the board, new product techniques, industry best practices and more.

Here are some handy tips which when followed, will go a long way in ensuring pcb assembly services

Use your PCB Assembler as a valued resource as you start to design your PCB Typically PCB Assembly is regarded as a process that comes at the end of the cycle. The fact, however, is that you need to consult your PCB Assembly partner early. In fact the PCB Assembler can give you important inputs at the design stage itself, given their vast experience and expertise. Not doing so, may mean that you have to contend with costly changes, which could also delay your go-to-market which itself can turn out to be an expensive affair.

Look for Onshore Assembly While cost can be a key determinant when it comes to offshore assembly, the fact is that there can be many hidden costs that can cost you dear. Consider the cost of getting low quality products or delay in delivery. These issues can offset the initial low cost that you would have factored in your product pricing.

Choose the PCB Assembler wisely Often times you may land up choosing a supplier, who is the sole supplier of the PCB parts. There is always the risk of being stuck if the supplier cannot deliver parts on time or if he discontinues production of a certain part. In such cases you would not have any back up. Often times this criteria may not feature in your decision-making matrix, but is exceedingly important, nevertheless.

Consistency in labeling It is important to ensure that your labels are consistent- be they on the design document or the component parts. While we are careful of the document labeling, component labeling does not get too much attention from us. However any inconsistency may lead to wrong components that can impact your product.

Readability Ensure there is readability on your documentation and that all parts are numbered correctly. Any miscommunication can cost you dearly.

File Formats Similarly, ensure that there is parity in the file formats. It shouldn’t happen that the assembler isn’t comfortable with the formats you send and that leads to wastage of time. This is fairly important as not all assemblers cater to all file formats. Gerber & CAD remain among the two popular formats.

Make use of the tools available with the Assembler The PCB Assembler can help you with the initial design and schematic creation. This can go a long way in ensuring that there are no issues at a later stage which can prove to be extremely costly as you would need to redo the prototype not to mention the fact that you would also have lost out on precious time.

DFM Reviews It is also prudent to conduct a DFM Review before you send the design to the PCB Assembler. DFM or Design for Manufacturing checks to see whether the design aids the manufacturing process. DFM can identify many issues such as those to do with spacing or component polarity, for example. It can go a long way in pointing out discrepancies if any at the outset instead of in the end.

List the desired capabilities It will help to list the desired capabilities that you want in the board. Is strong signal transmission your primary requirement or high power output a key requirement. Accordingly it will help to arrive at a design. There could be the need to arrive at some trade-offs basis what your objectives are. This will also ensure that the final product matches your expectations and that there are no discrepancies. If there is a way to enhance the capabilities given your specific requirements, the Assembler may come back with recommendations too.

Ensure you factor in the lead time It is important to factor in the lead time when it comes to both the design phase as well as the assembly phase. This will in turn help you arrive at your time-to-market accurately. It will also help to test before you place the final order as you will be able to check how reliable the partner is. This, in turn, will give you the necessary confidence in moving ahead.

SMT Manufacturing Made Simple with Advanced Circuits PCB Design and Production

Surface mount technology (SMT) is a design and fabrication process that replaces the through-hole mounting of PCB (printed circuit board) components with direct placement on the printed circuit board surface. It is something that is at work in the vast majority of PCB designs tucked inside modern electronics. The computer, phone, TV, and refrigerator someone uses every day is the end result of both SMT manufacturing and PCB production and assembly. Reference

However, the creation of PCBs with SMT manufacturing is quite complex and demands the use of advanced tools and technologies. DFM, or design for manufacturing, as an example, is the “coupled” process that integrates the basics of the PCB and takes into consideration the SMT manufacturing phases as well as the functionality of those SMT processes.

Will the design work as is or will there be a reworking of the PCB necessary? This is one of the major questions asked at the preliminary or prototyping phase, and often the SMT manufacturing component takes the back seat. However, as a design makes its way through the approval processes, SMT manufacturing has to enter the equation. Not only because it is essential to the actual function of the end product, but because it is such a cost-effective measure when hole-drilling can be eliminated.

The benefits of opting for SMT manufacturing include:

Cost-cutting – The time and complexity of drilling is eliminated when surface mounting can be used instead

Capabilities increased – The weight of a PCB that uses SMT manufacturing rather than drilling and soldering pastes means that the capabilities are improved, too. The era of the smaller and smaller device means that this design capability can open many previously closed doors.

Automation – It makes sense to leverage the ability to mass-produce PCBs that retain performance and quality, and SMT manufacturing is a key approach to consistency when producing in mass quantities.

Of course, when considering SMT manufacturing, it also means being able to simultaneously ensure that the design is easily produced and effective. This is where Advanced Circuits can step in and make all of the difference. We have a nearly flawless system that alleviates design flaws in the pre-production process, and helps to cut down on rework that is often the bane of SMT manufacturing.

PCB and SMT Design Resources Bring Optimal Outcomes

When to Use PCB Prototype Service and When to Switch to Standard Production Service

Developing a new PCB-based solution can be a time consuming and laborious process. Reducing the time and cost associated with the development process can greatly improve your next project's chance of success. In this article, we will discuss the advantages of beginning your design verification with prototype PCBs and then the advantages of shifting to standard-grade PCBs once you have validated your design. Reference 

PCB Prototype Service vs. PCB Standard Production

PCBCart offers both PCB Prototype and Standard PCB. Since you will normally eventually use both services, there is an appropriate time for each. The difference is simple. With the prototype service, we take your design and quickly build a small batch of boards using basic materials, which we then ship to you in just a few days. The idea is just to give you a sense of whether your design works or not and worth it to do a full production run. You can test the boards to locate any design flaw before you make a big investment in PCB fabrication based on that design.

In standard PCB production, we are actually making the boards you will use in your applications. This will take a bit longer since we may be using different materials and more complex fabrication processes (e.g. multi-layer designs), but it will usually still be as fast or faster than other PCB fabrication services. You will normally make a larger run of these since you will actually be using these boards for your market applications.

If you are working from an existing design you have used before, you may want to jump directly to the standard PCB production service. Since design flaws are much less likely, it could save you some time to get the standard boards you need right away. If you are testing a new design, we highly recommend you engage our PCB prototype assembly service . You will lose little time and be able to verify that your design works before standard production, which could save you considerable time and money if you do uncover design flaws.

Get Your Next PCB Design off the Ground with PCB Prototype Service

When you are just starting the development of a new product our rapid PCB prototyping service can help you get your new design from concept to production in record time. When developing a new product, quickly iterating through new versions of your design is of the utmost importance. Rapidly testing and correcting designs is what will allow you to hone in on a finished product as quickly as possible. Additionally, it is also well known that making large engineering changes to design is best done in the early phases of product development. PCB Prototyping service can allow you to locate just such design change requirements early in the development cycle. Spot design errors in low quantity prototype production run of your PCB board before ramping up production volume. Hence, it allows you to refine your next design quickly at an affordable cost.

As the saying goes, "time is money" and waiting on long lead time PCBs can doom a project to failure. That is why we offer quick-turn PCB prototype service, which builds your proto boards in as few as 2 working days. Additionally, this service is well suited to low volume production runs with a minimum order quantity of only five boards.

Although our prototype PCBs do not have as high of production tolerances as standard circuit boards, they allow you to get a very good idea of how well your final production version work. Having an accurate view of how your final design will turn out is of great importance to ensuring that your design is successful. Our prototyping service provides you with a nearly identical product to that of a high volume standard production run, albeit at slightly lower manufacturing tolerances. Despite the lower production tolerances, we support track widths down to 4mils and track spacing down to 4mils, 5mils minimum annular rings and minimum drill sizes down to 0.2mm (8mils). Additionally, we can manufacture PCB up to 16 layers in layer count and 500x500 mm in size, covering most PCB applications. Reviewing these capabilities, it is apparent that our prototyping service will allow you to test and verify demanding tight tolerance designs at a lower cost, with shorter turnaround times than what you would encounter with standard PCB services.

When developing surface mount based solutions, it's also of great utility to order solder stencils for prototype assembly purposes. You need to test your circuit design and make sure it is good for huge production.

PCB Prototype Advantages: • Opportunity to do a small test run of your PCB design; • Fast turnaround on your order; • Identify any design flaws fast; • You can change the design without having wasted an entire standard production run;

PCB Prototype Disadvantages: • The boards’ tolerances are not as high as standard circuit boards; • You will need to wait until you receive and test the prototype boards before formally ordering your standard production run; • Limited board materials; • A limited number of layers for your boards.

For more information on the advantages of using our prototype pcb services, find out more about Prototype PCB Benefits.

Transitioning to Standard PCB Service Once You Have a Finalized Design

Once you have an optimized prototype design in hand, we can help you take the next step with a high volume production run of standard PCBs using our Standard PCB service, which has tighter production tolerances than prototype service. It supports track widths down to 3mils and track spacing down to 3mils, 3mils minimum annular rings and minimum drill sizes down to 6mils and even includes free DFM analysis. We're capable to print advanced circuit boards in dimensions up to 600x700 mm, allowing you to implement even the largest PCB designs. In the event that you have a very demanding design or large design, our Standard PCB service will allow you to meet the challenge.

Included in the standard PCB service is our Design for Manufacture analysis of all standard PCBs to ensure that your PCB design will turn out as expected. We will look for all issues that could potentially sidetrack your PCB, including potential acid traps, missing solder mask between fine pitch device pins and other design rule violations. This value-added service is applied to ensure the success of your PCB projects.

When you are ready to transition a design from the prototype phase to the production phase our Standard PCBs are the solution. We can provide you with greater costs savings when ordering in higher volumes and provide you with a tighter tolerance product. Our standard PCB service is your solution for PCB production order.

Standard PCB Production Advantages: • No need to wait to receive and test prototypes — you can get your boards into your applications much faster; • Can order complex boards — different substrate materials, many layers, etc.; • Can order a large production run — save money with a bulk rate on larger orders;

Standard PCB Production Disadvantages: • If you discover a flaw in your design, the entire production run could go to waste; • No opportunity to tweak and improve the design before production; • Correcting errors could prove to be much more costly and time-consuming than using PCB prototype service first.

What is meant by the abbreviations PWB, PCB or PCBA for printed circuit boards?

In the world of electronics and mechatronics, printed circuit boards are often unavoidable. Printed circuit boards are present in machines, computers and consumer electronics, among other things. A printed circuit board or print is a carrier of various electronic components. These electronic components differ in shape, color, and function. The printed circuit board itself is made of epoxy, fiberglass or plastic and contains various copper wiring. These copper wiring are also called tracks and are applied between the various components by means of milling techniques and etching techniques. The copper wiring conducts the electrical current between the various components.

Which components are attached to printed circuit boards? The components on the printed circuit board then ensure that operations are performed. For example, resistors can cause the electrical current to be weakened and a capacitor can cause an electrical current to be collected and repelled. In addition to the capacitor and resistors, however, there are various other components that can be mounted on a printed circuit board. Examples include thyristor, diodes, Zener diodes, transistors, LEDs and ICs.

Preprinting and mounting of printed circuit boards Preparing printed circuit boards is preparing components for placement on printed circuit boards. The word prepped is derived from the English term: 'to prepare' which means preparation or preparation. The actual placement of the components on the printed circuit board is also referred to as mounting or mounting. The pieces can be done in two ways:

By means of Surface Mount Technology SMT, installing an SMD Surface Mounted Device. Direct soldering of components on the printed circuit board. This is usually done with small components through machines. These machines are also called pick and place machines or P&P.

Cut through-hole. Hereby the components are made through holes in the printed circuit board through fixing pins. This is especially the case with experiment printed circuit boards and can be done either manually or with the help of special machines.

PWB and PCB abbreviations for printed circuit boards Many English terms are used in mechatronics and electronics. Different English terms are also used for printed circuit boards. In the Dutch language, a printed circuit board is also referred to as printed wiring or printed circuit. In English, there are also different terms for printed circuit boards. In English, a printed circuit board is normally referred to as a printed circuit board. This is also abbreviated with PCB. In addition, the English term printed wiring board (PWB) is also mentioned for printed circuit boards, but this term is less common.

Difference between PWB and PCB IPC is a professional organization that is committed to standardization in the electronics industry. This body has several branches around the world including a number of branches in Europe in Sweden in Stockholm. IPC tries, among other things, to provide clarity in electronics by providing descriptions and definitions about the components and techniques used in electronics. The IPC describes, for example, the distinction between a printed wiring board (PWB) and a printed circuit board (PCB). The difference between a PWB and a PCB is explained by the IPC based on the purpose where the relevant circuit board is used:

A printed wiring board or a PWB is a printed circuit board that is only used as a connecting element.

A Printed Circuit Board or a PCB is a printed wiring board, but it also contains electronic functions in addition to through connections.

What does the abbreviation PCBA mean? The abbreviation PCBA is described in English as follows: Printed Circuit Board Assembly companies. This is a Printed Circuit Board with soldered components on it. After mounting a printed circuit board, one has a PCBA, but in practice, it is almost always referred to as a PCB or a printed circuit board.

PCB

In the early years, only single-sided printed circuit boards, but later also double-sided, metalized and multilayer printing. For every "question" we provide production "answer". Depending on your needs, print type, and version, you can continuously scale-up: from 1 piece in 24 hours to 10,000 prints per month, no problem! The printed circuit boards that we supply can be divided into the following groups: - Single-sided printed circuit boards - Single-sided printed circuit boards with a metal core (IMS / Metalboard) - Double-sided Metallized printed circuit boards - Multilayers (4, 6 or 8 layers) - Flex and Rigid-Flex circuit boards Printed circuit boards can be produced in a number of different versions, for example, printing can be carried out with a thicker copper layer so that the print tracks and higher amperage can cope, also a thicker base material can be used which makes the print stronger. Finishing a print also brings a number of options.

A summary of these options and extras gives the following list: - Delivery times - Material type - Material thickness - Copper thickness - Corners, slots and deviating shapes - Penalisation (breaker panel / v-cut) - Reference holes / Fiducialmarks - Flashgold - Soldermask - Silkscreen - HASL or OSP - Electrical testing Delivery times In principle, a standard delivery time of 11 working days applies to all types of printed circuit boards. Sometimes this may differ due to a larger number, or by adding additional options (eg flashgold). Faster delivery times (2 to 3 working days) are also possible, but this does depend on the current orders. Therefore always inform first what the possibilities are before you place an urgent order, and also clearly state that it concerns an urgent order. Material type - Epoxy FR4 (standard) - CEM - Pertinax Phenol paper Material thickness - 1.6 mm (standard) - 0.2 mm / 0.5 mm / 0.8 mm - 1.0 mm / 2.4 mm  Special thicknesses on request Copper thickness - 35 µM (standard) - 18 µM - 70 µM  Thicker copper layers on request Corners, slots and different shapes Because the printing board and milling machine nowadays use highly advanced CNC drilling and milling machines, the possibilities in the field of milling are almost unlimited. In principle, your print can be milled in all possible shapes, and slots or other cut-outs can also be made in the print. All prints are milled as standard, creating a nice right-angled print edge free of fibers. Penalisation (breaking panel / v-cut) In consultation, we can supply printing in a panel based on a drawing supplied by you, contour in the Gerber file, or you make known what your specific wishes are and we put the panel together for you. With a breaker panel, the prints are milled almost completely around and remain stuck on a number of breakers. This means that you do not have to assemble the individual PCBs piece by piece, but you can assemble the entire panel immediately. After assembly, you can then simply break the prints out of the panel, after which you will have loose prints again, where you only have to pass a file at a number of places. If the prints are only separated by straight lines, it might be better to separate the prints by a v-cut milling line. The method mills the material on both sides for 1/3 under a 'v' corner. This creates a weak spot exactly in the middle of that line. The material is still strong enough to be able to assemble, but can easily be cut or broken off after assembly. Reference holes / Fiducialmarks Fiducials or fiducial marks are markers or reference points that an SMD pick and place robot needs to properly position a panel and then provide it with SMD components. If you have new prints or panels that must be fitted with SMD components, you can indicate this with your order and we will place the fiducials on the panel for you. Round fiducials are standard on the panel, but other shapes can also be used when necessary. There are also SMD robots that do not use, or make limited use of, fiducial marks, or printed circuit boards that are assembled in control frames where a dowel system is required. For these axle assembly types, it is, therefore, necessary to provide dowel holes or reference holes in the panels in order to position the panel. When you indicate the positions of the holes on your layouts, we ensure that they are placed in the print or panel. Gilding (Flashgold) When your print is going to be used as a plug-in card or PC card, a good electrical connection is often required. When this connection is made without connectors it is sometimes better to gild the (hard edge) contacts. Unfortunately, selective gilding is no longer possible, so these prints are fully equipped with flash gold. Flash gold is also the best option when placing fine pitch SMD components. Finishing your PCB with flash gold ensures that the surface of the print remains as flat as possible. This is in contrast to the standard HASL, where the surface remains bumpy. The islands also remain protected against oxidation, and yet easy to solder. Soldermask An (anti) solder mask is a (green) lacquer layer that covers the entire circuit board with the exception of the islands (pads). This is necessary when the print contains smd components and when the print is to be soldered in an automatic soldering process such as a wave soldering machine. Because the entire print is covered with the (anti) solder mask, this prevents tin from sticking to the tracks on the print and therefore soldering only where one wants it, namely only on the islands. With prints that contain smd components, it is almost a must to use a (anti) solder mask, because when the prints go through the reflow oven there is a chance that the smd components will float on a tin layer already applied to the print. Silkscreen A text print or silk screen is also a lacquer layer that can be put on the print in order to make the component outlines and component values ​​or references clear. A text print is usually white, but may also be applied in a different color. When the print is assembled or perhaps will be repaired at a later stage, it is useful to have such a text print on the print. It is easier to see on the print where the components should be placed than first on a drawing and then on the print. HASL or OSP All the prints that we produce come standard with a lead-free HASL finish. HASL stands for Hot Air Solder Leveling and is a certain technique for applying a layer of tin / silver / copper or tin / copper / nickel alloy on the pads and / or traces of a printed circuit board. Advantages of the HASL finish on printed circuit boards are: Pads are already tinned and therefore easy to solder. All traces and pads not covered by the solder mask are protected against (copper) oxidation. Disadvantages of HASL is that in some cases it gives an increased chance of short circuits when the pitch of components becomes smaller and that SMD pads in particular are sometimes no longer flat. For printed circuit boards with a large number of smd components and / or finepitch (smd) components, we do not recommend the use of HASL. In these cases choose flashgold or OSP. If you do not want your pcb assembly illinois to be (standard) tinned, please indicate this with your order. For example, we can provide your printing with OSP. With organic Passifers (OSP) we apply a kind of lacquer layer that protects the solderability of the copper pads against oxidation. Inspection and final inspection By default, all prints are visually inspected for (production) errors. For more advanced printed circuit boards that can no longer be visually inspected, electrical test equipment can be used. For example, printing can be tested using a bed-of-nails or pen bed tester, or a flying probe test machine. These test devices have the advantage that after this electrical test, the PCBs are 100% electrically in order. All multilayers supplied by us are tested using a flying probe as standard. Electrical testing is of course also possible on all other print versions.

Diagnosis and Repair of Logic Boards

If your MacBook has a defective logic board, you can throw it away. Yet? If you consider how often 'you buy a new one' is the result of a visit to the repair shop or computer store you would think that there is no other solution. I thought so myself too until I started to delve into the repair of these printed circuit boards. After much trial and error, I know better; Logic boards can indeed be repaired; a MacBook with moisture damage due to a glass of cola in its gut or a short circuit through a faulty Chinese charger can often be saved.

In many cases, the defect can be traced back to one or two parts. To replace these parts, the necessary knowledge, expertise and suitable equipment are important. I now have that. If you have been told that your laptop cannot be repaired due to a defective motherboard, or if the costs for repair are so high that it is no longer profitable, do not give up and bring it along. You will quickly hear a diagnosis and costs for repair of the MacBook. The usual costs for this repair service can be found at rates. 

In addition to the MacBooks logic boards, motherboards for laptops running on windows can also be repaired.

Have a repair carried out?

Guarantee

Repairs carried out by me have a 3-month warranty. Physical or moisture damage after the repair is excluded from the warranty.

Other PCB repairs

Replacement of fuses, resistors, capacitors, and other SMDs is no problem, as is repairing traces (to a certain extent). Making a diagnosis for circuit boards unknown to me is a lot more difficult, certainly without a flow chart. The success rate is lower in such cases, but whoever does not dare does not win.

Repair time

PCB assembly rework to a logic board or motherboard takes more time than simple replacement repairs. Keep this in mind when you offer the laptop for repair. Take into account a working day or three if I have all the supplies in stock. If not, it will take longer. After a preliminary investigation, I can provide more clarity about the expected repair time.

No cure no pay

In the event of a failed or impracticable repair, you pay nothing unless otherwise agreed in advance.

Get to know a little about Aluminium PCB

Aluminium printed circuit boards contain a thin layer of thermally conductive dielectric material that transfers heat

There are many names for these products; Aluminum clad, aluminium base, metal clad printed circuit board (MCPCB), an insulated metal substrate (IMS or IMPCB), thermally conductive circuit boards, etc. ... but they all mean the same thing and work in the same way.

How are aluminium PCBs made? A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired switching pattern and the metal base draws heat away from this circuit through the thin dielectric.

Advantages of aluminium PCBs Heat dissipation is dramatically better than standard FR-4 constructions.

The dielectrics used are typically 5 to 10 times as thermally conductive as conventional epoxy glass and one-tenth of the thickness

Thermal transfer is exponentially more efficient than a conventional rigid PCB.

Lower copper weights than suggested by the IPC heating charts can be used.

Applications of aluminium PCBs Although Power Converters and LEDs are the largest users of these products, Automotive and RF companies also want to reap the benefits of these constructions. Although a single layer construction is the simplest, Amitron has other configuration options, including:

Flexible aluminium PCBs One of the newest developments in IMS materials is flexible dielectrics in PCB assembly Chicago. These materials are equipped with a polyimide resin system with ceramic fillers that offers excellent electrical insulation, flexibility and natural thermal conductivity. When applied to a flexible aluminium material such as 5754 or similar, the product can be moulded to obtain a variety of shapes and angles that can eliminate expensive fixtures, cables and connectors. Although these materials are flexible, they are meant to be bent and stay in place. They are not suitable for applications that are intended to be bent regularly.

Hybrid aluminium PCB's In a 'hybrid' IMS construction, a 'sub-assembly' of a non-thermal material is independently and subsequently processed bound to the aluminium base with thermal materials. The most common construction is a sub-assembly with two or four layers made from conventional FR-4. By attaching this layer to an aluminium base with thermal dielectrics, heat can be dissipated, stiffness is improved and it can act as a shield. Other benefits are:

Less expensive than a construction made of all heat-conducting materials

Offers superior thermal performance over a standard FR-4 product  

Can eliminate expensive heat sinks and associated assembly steps

Can be used in RF applications where a PTFE surface layer is desired due to the loss characteristics.

Use of component windows in the aluminium to accommodate components with through holes. This allows connectors and cables to pass connections through the substrate while the solder hook creates a seal without special gaskets or other expensive adapters.  

There are many workplaces for PCB assembly Chicago to visit and get your work done. Visit today to know more about the newest in the field of electronics.
