What is PCB Assembly ?

PCB Assembly manufacturer - Hitech Circuits Co., Limited

 It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It’s these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology“.  The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Generally, this technique employs the use of state of the art machines, which are fully automatic. For example, the surface mount components are worth positioning with the aid of an automated pick and place machine.

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques

This method is favorite for use with through-hole parts, which needs manual placement on the board. Besides, with these through-hole parts, it’s advisable you use wave soldering. Note that in the through- hole assembly process, you need to place the components and electronics on the PCB.

After that, you use wave soldering to solder the leads. Typically, you will need an individual to insert a component into a marked PTH. Once done, transfer the PCB to the next station where the next person will be on standby tasked with fixing another part.

What are the Benefits of SMT PCB Assembly?

SMT assembly provides many benefits and some of them are as follows:

It can be used to incorporate small components.

In SMT, the components can be placed on both sides of the board.

It assures high component densities.

Fewer holes need to be drilled for surface mounting than through-hole.

It require low initial costs and time for setting up the mass production.

SMT is the simpler and faster-automated assembly when compared to through-hole.

Errors regarding the component placement can be easily rectified. 

Surface mount  PCBs feature strong joints, which can easily withstand vibrations. 

What are the techniques used in Surface Mount Technology?

There are several techniques for the reflow process. After applying the solder paste or a flux mixture on the board and after placing the components, the boards are conveyed to a reflow soldering oven. The techniques used for reflowing soldering include infrared lamps, hot gas convection, fluorocarbon liquids with a high boiling point, and so on.

What are the different testing methods used in SMT PCB Assembly?

Hitech Circuits as the PCB assembly manufacturer, we perform the following testing and inspection to ensure the quality of surface mount PCBs.

Automated Optical Inspection (AOI): This is performed before and after the soldering to identify the component placement, presence, and solder quality.

X-ray Testing: In this type of testing, the operator relies on the X-ray images of the PCB to check the solder joints and lead-less components such as Quad Flat Packs and ball grid arrays, which are generally not visible to naked eyes.

In-Circuit Testing (ICT): This method is used to detect manufacturing defects by testing the electrical properties in the SMT Assembly.

What type of files or documents should I send for SMT PCB Assembly? 

Gerber Files: The file contains all details of physical board layers including solder masks, copper layers, drill data, legends, and so on.  

Bill of Materials (BOM): This contains information on the list of items needed for the PCB manufacturing and the instructions of manufacturing. 

Pick and Place File: This file contains information on all components to be used in the PCB design and their rotation and X-Y coordinates.

The whole process of PCB Assembly

1. Bare board loader machine

The first step in the PCB assembly is to arrange the bare boards on the rack, and the machine will automatically send the boards one by one into the SMT assembly line.

2. Printing solder paste

When PCB on the SMT production line, firstly, we have to print solder paste on it, and the solder paste will be printed on the pads of the PCB. These solder pastes will be melt and solder the electronic parts to the circuit board when it passes through the high-temperature reflow oven.

In addition, when testing new products, some people will use film board/adhesive cardboard instead of solder paste, which can increase the efficiency for adjusting the SMT machines.

3. Solder paste inspection machine(SPI)

Since the quality of solder paste printing is related to the quality of welding of subsequent parts, some SMT factories will use optical machine to check the quality of solder paste after printed the solder paste in order to ensure stable quality. If there any poorly printed solder paste board, we will wash off the solder paste on it and reprint, or remove the excess solder paste if there is redundant solder paste on it.

4. High speed SMT machine

Usually, we will put some small electronic parts (such as small resistors, capacitors, and inductors) to be printed on the circuit board first, and these parts will be slightly stuck by the solder paste just printed on the circuit board, so even if the speed of printing is very fast and the parts on the board will not fall away. But large parts are not suitable for use in such high speed SMT machines, which will slow down the speed of small parts assembly. And the parts will be shifted from the original position due to the rapid movement of the board.

5. Universal SMT machine

Universal SMT machine is also known as "slow machine", it will be assembled some large electronic components, such as BGA IC, connectors, etc., these parts need more accurate positions, so the alignment is very important. Use a camera to take a picture to confirm the position of the parts, so the speed is much slower than High speed SMT machine we taked before. Due to the size of the components here, not all of them are packed in tape and reel, and some may be packed in trays or tubes. But if you want the SMT machine to recognize the trays or tube-shaped packaging materials, you must configure an additional machine.

Generally, traditional SMT machines are using the principle of suction to move electronic parts, and in order to place the parts successfully, and there must be the flat surface on these electronic components for the suction nozzle of the SMT machine to absorb. However, for some electronic parts don’t have a flat surface for these machines, and it is necessary to order special nozzles for these special-shaped parts, or add a flat tape on the parts, or wear a flat cap for thees electronic parts.

6. Manual parts or visual inspection

After assembled all parts by the high speed SMT machine or Universal SMT machine and before going through the high-temperature reflow oven, and we will set up a visual inspection station here and to pick out the deviation parts or missing components boards etc., because we have to use a soldering iron to repair if there are still defectives boards after passing the high-temperature oven, which will affect the quality of the product and will also increase the cost. in addition, for some larger electronic parts or traditional DIP parts or some special reasons cannot be processed by the SMT machine before, they will be manually placed on pcb here.

7. Reflow oven

The purpose of reflow oven is to melt the solder paste and form a non-metallic compound on the component feet and the circuit board, that means to solder electronic components on the circuit board. The temperature rise and fall curves often affect the soldering quality of the entire circuit board. According to the characteristics of the solder materials, usually the reflow oven will set the preheating zone, soaking zone, reflow zone, and cooling zone to achieve the best soldering effect.

For example, the melting point for SAC305 solder paste with lead-free is about 217°C, which means that the temperature of the reflow oven must be higher than the melting points to remelt the solder paste. What's more, the maximum temperature in the reflow furnace should not exceed 250°C, otherwise many parts will be deformed or melted because they cannot withstand such a high temperature.

Basically, after the pcb passed through the reflow oven, the assembly for the entire circuit board is almost complete. If there are hand-soldered parts, we need to transfer to DIP process, and then we have to check the quality after reflow oven by QC department.

8. Automatic optical inspection(AOI)

The main purpose of setting up AOI is because some high density boards can’t be process the following ICT test, so we used AOI inspection to replace it. But even using AOI inspections, there still have the blind spots for such checking, for example, the solder pads under the components cannot be checked by AOI. At present, it can only check whether the parts have side standing issue, missing parts, displacement, polarity direction, solder bridges, lack of soldering etc., but cannot checking the BGA solderability, resistance value, capacitance value, inductance value and other components quality, so far AOI inspection can’t completely replace ICT test.

Therefore, there is still some risk if only AOI inspection is used to replace ICT testing, but ICT test is also not 100% make sure the good quality, we suggest these two ways can be combined with together to make sure the good quality.

9. PCB unloader machine

After the board is fully assembled, it will be retracted to the unloder machine, which has been designed to allow the SMT machine to automatically pick and place the board without damaging the quality for PCB.

10. Visual inspection for finished products

Normally there will be a visual inspection area in our SMT production line whether there is an AOI station or not, and it will help to check if there are any defectives after completed assembled the pcbs. If there is an AOI station, it can reduce the visual inspection worker on our SMT line, and to reduce the potential cost, and because it is still necessary to check some places that cannot be judged by AOI, many SMT factories will provide the mainly visual inspection templates at this station, which is convenient for visual inspection worker to inspect some key parts and polarity for components.

11. DIP process

DIP process is a very important process in the whole PCBA processing, and the processing quality will directly affect the functional for PCBA boards, so it is necessary to pay more attention to the DIP process. There are many preliminary preparations for DIP process. The basic process is to re-process the electronic components first, like to cut the extra pins for some DIP components, our staff received the components according to the BOM list, and will check whether the material part numbers and specifications are correct or not, and performs pre-production pre-processing according to the PCBA samples. The steps are: Use various related equipment (automatic capacitor pins cutting machine, jumper bending machine, diode and triode automatic forming machine, automatic belt forming machine and other machines) for processing.

12. ICT test

Printed Circuit board open/short circuit test (ICT, In-Circuit Test), The purpose of ICT test is mainly to test whether the components and circuits on the printed circuit board are open or short issues. It can also measure the basic characteristics of most components, such as resistance, capacitance, and inductance values to judge whether the functions of these parts are damaged, wrong parts or missing parts etc. after passing through the high-temperature reflow oven.

ICT test machines are divided into advanced and basic machines. The basic ICT test machines are generally called MDA (Manufacturing Defect Analyzer). It’s just to measure the basic characteristics of electronic components and judge open and short circuits issue we talked above.

In addition to all the functions of the basic ICT test machines, for advanced ICT test machine can also test the whole PCBA by using power, start to testing the PCBA boards by setting the program in the test machine. The advantage is that it can simulate the function of the printed circuit board under the actual power-on condition, this test can partly replace the following functional test machine (Function Test). But the cost for the test fixture of this advanced ICT test can probably buy a car, it’s too expensive and we suggest it can be used in mass production products.

13. PCBA function test

Functional testing is to make up for the ICT test, because ICT only tests the open and short circuits on the the PCBA board, and other functions such as BGA and other fuctions are not tested, so it is necessary to use a functional testing machine to test all functions on the whole PCBA board.

14. Cutting board (assembly board de-panel)

Normally, printed circuit boards will be produced in panel, and it will be assembled to increase the efficiency of SMT production. It means several single boards in one panel, such as two-in-one, four-in-one etc. After finished all the pcb assembly process, it needs to be cut into single boards, and for some printed circuit boards with only single boards also need to cut off some redundant board edges.

There are several ways to cut the printed circuit board. You can design the V-cut using the blade cutting machine (Scoring) or directly manually break off the board (not recommended). For more high density circuit boards, it will be used the professional splitting machine or the router to split the board without any damage the electronic components and printed circuit boards, but the cost and working hours will be a little longer.

Low Volume PCB Assembly

What is Low Volume PCB Assembly?

sales12@hitechpcb.com

Low Volume, Small batch, as the term implies, is a batch with limited number of assembly batches. While some OEMs manufacturing electromechanical products require PCB Assembly in bulk, a Low Volume PCB Assembly may be required for a limited edition product or one with very specific requirements. In such a scenario, it is crucial to first make a low volume prototype PCB assembly as that would give an idea about the final product and if it requires any changes.

Hitechpcba is an experienced full service electronics contract manufacturer; however, volume has never been an issue for us. We offer PCB assembly services including prototyping even for low volume orders and regardless of the complexity of the requirement.

There are many names for small batch printed circuit board (PCB) assembly. Other names you will commonly hear are: surface-mount technology (SMT) PCB prototypes, PCBA prototype assembly, PCB sample assembly, etc.

The term PCB assembly refers to a fast prototype PCBA used to test the function of new electronic designs. These help with quality assurance, verifying that there is no problem with the test product, finding bugs, and updating the design. Typically, before mass production, one electronic project will need 2-3 iterations of a SMT assembly to make sure everything is working perfect.

Hitechpcba has a strong engineer team to back up; most of them with over 10 years in the electronic manufacturing fields. If you need a small batch of boards; there are customization requirements for component packaging, component specifications, assembly techniques or density levels. You can contact Hitechpcb as a reliable OEM PCB assembly manufacturer. And we can provide the Low Volume PCB Assembly service you need at your budget.

1. Small-batch, multi-variety SMT lean production in quality control and large-scale production is not much different, just because of frequency. There are a lot of online adjustments and exception handling processes every day. In the small-batch, multi-variety production state, the operator is not only will be simple work in feeding and feeding but also skilled in parameter adjustment, machine abnormal processing and other skills. and in the high-volume production state, the main work of the operator is only for simple operations such as feeding. Starting from production and quality control. Operators with comprehensive skills, carefulness and a strong sense of responsibility should be arranged to carry out small batches and multi-variety production. The smaller the batch, the more complicated Products, the higher the dependence on the operator, so it is necessary to strengthen the training, there are a corresponding incentive and responsibility system to improve the operator’s professional skills.

2. Emphasize that quality is produced rather than tested, and process quality management is used to ensure final quality. During the production process Quality inspection and control are carried out in every process. Focus on cultivating the quality awareness of each employee to ensure timely quality problems

Hitechpcba supports engineers to assemble their electronic prototype quickly and cost effectively during the whole design verification process. To ensure that the product design meets requirements, in general, we suggest 5 pcs or 10 pcs for prototype circuit board assembly testing. Of course, one or two piece is also OK, so long as it can be verified.  

There is no Minimum Order Quantity (MOQ) limit for PCB assembly -even one piece is accepted. Moreover, all components’ price is 100% based on your BOM list. If you need an equivalent replacement to reduce cost, we must get your official approval. Our team is qualified to manage the complete prototype PCB assembly process, which includes the sourcing of all components and their management, PCB assembly, quality control, function testing, and delivery.   

Our small batch printed circuit board assembly is a specialized service that enables us to take complicated designs, prepare them for assembly, and test them without your needing to worry about PCB assembly workmanship. The prototype pcb manufacturing section of our manufacturing facility has a unique layout that allows for flexible use of both automated and manual parts-loading stations. Our staff is qualified and experienced in managing fine-pitch parts and ball grid arrays (BGAs) for high-density FR-4 PCBs. Our team is capable of manufacturing prototype pcb manufacturing volumes from 1 to 1000 PCBs.  

What Low Volume PCB Assembly Services are Available?

Below are some of the low volume pcb assembly services available:

Surface Mount Technology (SMT) Assembly

SMT technology has to do with producing low-cost printed circuit boards. This technology functions by soldering the PCB components found on the surface. This is a modern way of mounting components. This doesn’t involve through holes drilling into the PCB.

This is included among the most efficient and affordable mode of mounting components. Asides from this, it is basic and simple, and only sees less or very few errors. This makes them great for low volume PCB assembly.

Through Hole Technology Assembly

This has to do with hole drilling through the printed circuit board. After the hole is drilled, the component will be mounted with legs through these holes. This will increase the bonding strength.

This method is also the most suitable when mounting straight components having high mechanical load. This includes switches and connectors. This technology should also be used to mount components, which would pass through mechanical and environmental stresses.

During prototyping, you will take very little time to mount and replace its components.

Leaded and Lead Free PCB Assembly

You may also choose leaded PCB assembly. This deals with using materials having lead products. This approach makes use of lead materials in the assembly of PCBs. You can as well choose lead-free PCB assembly that involves assembling PCBs with lead-free materials.

This approach of accepting PCBs at lower costs is an environmentally friendly one. You should also consider the use of low-cost lead-free PCB assembly. This is useful because it is less harmful to people’s health.

Multilayer, Double Sided, and Single Sided Multilayer PCB Assembly

Some PCB types, which can be assembled via low volume PCB assembly, are double-sided or single-sided pcbs among others.

Asides from this, you could also decide to assemble pcbs having multilayers. However, you should note that assembling multilayer PCBs will raise the cost of assembling printed circuit boards.

On this note, always avoid having too many PCB layers, if you have plans to lower the PCB assembly price.

Prototyping PCB Assembly Services

Immediately the design of your low volume PCB is ready, then you can make the prototype. This prototype will be used to give you a rough idea of the final look of your low volume PCB.

Asides from this, it will serve as the major blueprint, which will guide the whole process of manufacturing low-cost PCBs. Asides from this, the prototype also gives you a great visual impression of the design and then  lets you make some important adjustments.

If you make some changes to your design, never forget to update the BOM.

Quick Turn PCB Assembly service

Also, you’ll be opportune to have low volume PCB assembly at very high speed. This deals with assembling PCBs at a much faster rate while ensuring that the low budget is maintained.

It makes use of high tech machinery that will select and place the components of the PCB on the PCB at an advanced speed. Although the speed used in assembling the PCB is quite high, you’ll discover that the quality of the PCB will remain very high.

How to Choose a Low Volume PCB Assembly Manufacturer?

The prototype PCB assembly is a complex process. It’s not even a part of the actual circuit board manufacturing process, still, it holds immense significance. This is due to their undeniable benefits. Here are some important benefits of our prototype PCB assembly.

This type of PCB assembly helps in analyzing the design and functionality of the circuit board before its final production. This saves several possible failures by identifying bugs in the early stages of the manufacturing process. This helps save on cost, productive time, as well as resources.

The feasibility of the circuit can be checked in the design stage. Hitech Circuits lays emphasis on using design for manufacturability or DFM which helps offer quick and accurate output.

A good small batch PCB vendor can help you get your design into production without undermining the quality and reliability of your circuit. Don’t forget to keep these things in mind when selecting a small PCB vendor for your next project:

1) Make sure that the vendor has a positive reputation

2) Check if they have a solid online presence, both locally and on the web.

3) Make sure that they offer quick turnaround times and clear communication with customers.

4) Be sure to ask for details about design and assembly options, including layers, design rules, and parts availability.

5) Check out what the turnaround time will be for your project. Again, they should have a variety of options for you to choose from.

6) Do a little research on the vendor’s quality control processes and use this information when making your decision.

This guide is here to help you make the right choice when selecting a PCB vendor for your project. If you’re ready to get started with your design, find out how easy it can be with Hitechpcba.com

Estimating the Cost of a Prototype PCB Assembly Project

The ability to accurately predict the cost of your prototype pcb production project can prove a tough ask. However, you can always come up with estimates of the total costs. So how can you go about this? One of the best ways often entails getting a quote from your prototype PCB assembly manufacturer. The requirements, however, prove different with each prototype PCB assembly company. For instance, at Hitech Circuits PCB and Assembly, you can always get a complete price quotation in 24 hours once you have sent your PCB design file complete with a bill of materials. Further, you will have to enclose specific details such as the BOM list, your Gerber file, and the required prototype PCB quantities. Additionally, you will also have to specify any need for special technology utilization in the assembly process.

At Hitechpcba PCB and Assembly, no MOQ limit exists for prototype printed circuit board assembly, and you can always order even a single piece of PCB prototype. What’s more, the price of components will be based on the BOM list you send.  But you can always request the equivalent replacements to save the cost.

The company has the experience and capacity to handle your Low Volume PCB Assembly. And Hitech Circuits PCB manufacturing and pcb Assembly possesses the latest technologies and equipment to handle your Low Volume PCB Assembly needs ranging from one piece up to a thousand pieces. Hinging their operations on delivering quality PCB prototypes within short turn-around times, picking us will always prove an inspired decision.  

Another crucial aspect of estimating the cost of production depends on the services and PCB product sourcing avenues of the prototype PCB service provider. For instance, if the company has a qualified team of engineers and sources the parts necessary for your PCB design assembly process in house, then the cost drastically reduces. The opposite also rings true for companies that outsource services or PCB components. Here the price will always rise, and this can hamper your plans with the developed low volume PCB projects.

Finding a PCB turnkey service provider for yourLow Volume PCB Assembly and sources for the diverse components allows you to worry yourself with the design, which saves you money. Additionally, a company such as Hitech Circuits that sources for components ensure that the components used in the assembly process of the PCB prototype are of top-rate quality owing to the quality certification and standards that it must protect in its operations. With advanced optimal selection criteria for packaging, you also get to reduce the cost, a crucial indicator of the total cost of the prototype smt pcb assembly.        

Another crucial determinant of a Low Volume PCB Assembly service provider is labor charges, parts costs, and bare circuit board pricing or rates. To determine this, all you have to do entails accessing the company’s website, sending your prototype PCB Gerber file, and getting an estimate based on the supplier or assembly service provider.    

Most Low Volume PCB Assembly providers guarantee prompt delivery though this often depends on the capacity of the company and the documentation you submit. For instance, the average timeline always comes at two weeks when all factors remain constant. However, for Hitech Circuits, you will only need three days to get your delivery. Consequently, the quality and turn-around delivery times have to figure in your cost estimates, especially based on your budget and application needs.  It becomes crucial to note that we do a thorough evaluation of the engineering concerns and inquiries related to components before stating the PCB assembly process.

Как правило, PCB на основе меди имеет ту же структуру, что и PCB на основе алюминия - однослойная, двухслойная панельная монтажная поверхность, двухслойная двухэлементная монтажная поверхность и четырехслойная двухэлементная монтажная поверхность. Даже если они используют тот же предварительно пропитанный материал для изоляции медного слоя. Однако медная подложка (398W / mK) обладает лучшей теплопроводностью, чем алюминиевая (237W / mK).

A Comprehensive Guide to Circuit Card Assembly

Introduction

Circuit Card Assembly (CCA) is a critical process in the electronics manufacturing industry, involving the assembly of electronic components onto a printed circuit board (PCB). This process transforms a bare PCB into a fully functional electronic assembly, enabling the operation of various devices across numerous applications.

Key Components of CCA

Printed Circuit Board (PCB):

The foundation of the assembly, a PCB consists of a non-conductive substrate with conductive pathways etched onto it, connecting different components.

Soldering Techniques:

Different methods are employed to attach components to the PCB:

Hand Soldering: Used for small-scale or repair work.

Wave Soldering: Suitable for through-hole components; the board passes over a wave of molten solder.

Surface Mount Technology (SMT): Allows for the mounting of components directly onto the surface of the PCB, facilitating high-density assemblies.

The CCA Process

1. Design and Layout:

The assembly begins with the design of the PCB using Computer-Aided Design (CAD) software. This step involves laying out the components and their interconnections.

2. Component Placement:

Once the PCB is fabricated, components are placed on the board. Automated pick-and-place machines are commonly used to ensure precision and efficiency.

3. Soldering:

After placement, components are soldered to the PCB using one of the aforementioned techniques. Proper soldering is essential to create reliable electrical connections.

4. Inspection:

The assembled boards undergo inspection to check for defects, misalignments, or soldering issues. Techniques such as automated optical inspection (AOI) are often used.

5. Testing:

Functional testing is performed to verify that the assembly meets design specifications. This may include in-circuit testing, where each component's functionality is checked, and final functional tests to assess overall performance.

Quality Assurance

Quality assurance is paramount in CCA, involving rigorous testing and inspection processes to ensure that assembled boards meet industry standards. Common practices include:

ISO Certification: Many manufacturers adhere to ISO standards to ensure quality management.

Environmental Testing: Assemblies may undergo thermal cycling, humidity, and vibration tests to simulate real-world conditions.

Reliability Testing: Long-term tests assess the durability and performance of the assembly over time.

Applications of Circuit Card Assembly

CCAs are used in a wide range of industries, including:

Consumer Electronics: Smartphones, tablets, and home appliances.

Industrial Equipment: Robotics, automation systems, and control panels.

Medical Devices: Diagnostic equipment, monitoring devices, and surgical tools.

Telecommunications: Network devices, routers, and communication systems.

Automotive: Control units, infotainment systems, and safety features.

Conclusion

Circuit Card Assembly is a fundamental process in electronics manufacturing, bridging the gap between design and functionality. By transforming raw PCBs into operational assemblies, CCA plays a crucial role in the performance and reliability of electronic devices. As technology advances, innovations in assembly techniques and quality assurance continue to enhance the efficiency and capabilities of CCAs across diverse applications.
