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.

Why are more and more customers choosing PCBA one-stop service?

More and more customers are asking if their suppliers can provide PCBA one-stop service. Many of them purchased these two types of circuit boards and components separately after discovering them.

Therefore, more and more customers are choosing Printed circuit board & electronic components one-stop procurement services for the following reasons.

Firstly, the sales channels for components are networked, and prices tend to be transparent.

At present, the entire component sales network is actually available. You can find any type of material by entering the online model, price, manufacturer's production status, and whether there is inventory. In fact, the entire process is very simple. If the company purchases on its own, it needs to ask someone who knows the materials if the component supplier is genuine and when it can be shipped. But in this way, the final purchased materials may have the same price as the supplier, which is equivalent to spending more money on the same thing.

Secondly, labor costs increase and own cost decrease to cope with uncertainty

Faced with the current unstable situation, we can indeed feel that orders are not actually increasing, but decreasing. It is absolutely impossible to reduce labor costs without increasing orders. The entire PCBA one-stop service includes the entire budget, with controllable prices and no other costs, reducing uncertainty.

Thirdly, delegate professional affairs to a more professional team for handling

Compared to General Solutions, it may not have much understanding of the current price trends of PCB boards and components, as well as new SMT technologies, as it does not involve specific backend production processes. But PCBA manufacturers have to handle these backend processes every day. The engineers at the PCBA processing plant are very clear about what type of board and solder paste to use in what industry.

The most important point is that PCBA manufacturers have many customers and there is also a high demand for parts procurement. Correspondingly, you can obtain more terminal channels, thereby obtaining more products, so the price will definitely be lower and the quality will definitely be guaranteed. After all, end distributors do not want to lose their main customers. If you purchase from one company, you may not be able to meet the lowest quotation from other companies.

Are you looking for a reliable one-stop PCB assembly services provider for the electronic product of you company?

Hitech Circuits, an advanced PCB one-stop-shop solution provider, will show what is the one-stop electronic assembly services in this article below.

Chapter 1: What does it have in One-Stop PCB Assembly Services?

Chapter 2: One-Stop PCB Assembly Services Provider - HITECH CIRCUITS

Part 1: What does it have in One-Stop PCB Assembly?

One-stop PCB assembly belongs to electronics manufacturing services, and it includes PCB design, PCB manufacturing, electronic components sourcing, and PCB assembly.

The collaboration model between electronics solution companies and the one-stop PCB assembly service provider Hitech Circuits is:

Electronics solution companies work on project designs for product research and development > Hitechpcba reduces the project costs through appropriate PCB design > PCB manufacturing, assembly, test, and other services > shipping.

One-Stop PCB assembly specific process of Hitech Circuits:

Step 1. PCB board designing (optional) and PCB reverse

HITECH CIRCUITS can help the customers to improve the PCB design. If you have completed the PCB design, our professional engineers will check carefully your design to make sure everything is OK. We also can design the board for the customers. we need schematic source files or netlists, structure diagrams (dxf) and design requirements. If no schematic source files or netlists, it needs to provide a package library (if no package, need to provide a component data manual).

Besides, we also can do the PCB reverse engineering. if you can send me 2 good sample boards.

1.Tell me these details (Layers, board size, raw materials.) then we can give you a quote about making Gerber files and BOM.

this is the first step. If you agree with the quote, then you can send me board;

2.after making files, then we quote production cost for you. If you don't agree the production cost, then you just need to pay us the cost of making files.

Step 2. PCB board manufacturing

Before bulky PCB manufacturing, HITECH CIRCUITS can manufacture samples according to customers’ requirement and do the DFM, DFT, and DFX (design for manufacturing, test, excellence).

The PCB manufacturing process is:

PCB material preparation and processing > laminate PCB layers on the core > generate circuits on PCB layers > AOI (automatic optical inspection) > mechanical and laser drill on PCB layers > electroplate PCB holes by VCP (vertical continuous plating) > print solder mask and surface finishes > process the PCB edges > four-terminal sensing test (for boards of defense, aerospace, medical, automotive uses)

Meanwhile, we manufacture the SMT stencils for PCB assembly.

Step 3. Electronic components sourcing

HITECH CIRCUITS has its electronic component warehouse, with commonly-used components and some discontinued ST/TI components in stock. According to your BOM, we provide all components you want.

We source the components from local and reliable electronic components factories and direct suppliers from the globe. Through regional price differences, we can provide the best prices for you. All the electronic parts components are original ones.

Step 4. PCB assembly service

Before bulky PCBA manufacturing, we assemble 5 PCB boards and randomly choose one for the first article inspection (FAI). We generate an FAI report and send it to our client. We will start bulky PCB assembly when the client reviews and approves it.

The PCB assembly process is: solder paste printing > solder paste inspection > SMT assembly (high-speed assembly and function assembly) > X-ray inspection if there is BGA > reflow soldering > AOI > THT assembly > wave soldering > functional test (optional) > IC programming (optional) > thermal aging (optional) > conformal coating (optional) > box-built assembly (optional)

Step 5. Final shipping

We have our warehouse for printed circuit boards and PCBA. We will use FedEx, DHL, or UPS to deliver the boards to you as soon as possible. (Usually, we recommend FedEx. since it is cheaper). We also have our own forwarder which can provide competitive price.

Part 4: One-Stop PCB Assembly Services Provider – Hitech Circuits

Electronics manufacturers need a dependable partner to supply the electronic chip that goes into all our smart electronic gadgets. Whether it’s a luxury car or smartwatch, a remote-controlled child’s toy or a glucose monitoring kit at your local health store, the crucial printed circuit board (PCB) is an essential component.

Manufacturing a PCB involves a series of complex steps: printing and storing circuit boards, procuring electronic components, assembly, and testing to ensure functionality to specifications. Traditionally, OEMs used a multi-vendor, multi-partner approach to PCB sourcing, manufacturing, assembly, and testing. However, this method was too cumbersome, slow, expensive and error-prone. As a result, the demand for ready-to-use PCBs snowballed, and one-stop PCB assembly services became the preferred choice for electronics manufacturers and designers.

The importance of a one-stop PCB assembly services provider

End-to-end service providers give OEMs a competitive edge. They can turn their ideas into efficient electronics products, get them out into the market before their competition, and achieve early monetization.

When working with a one-stop PCBA (printed circuit board assembly) service provider, the same vendor sources components and assembles the PCB. Maintaining a single point of contact for the entire manufacturing process eases communication in case of any problems, changes, or modifications. As a result, you can resolve issues quickly and efficiently, eliminate bottlenecks in the production process, and significantly reduce PCB production lead times.

Hitech Circuits is your ideal partner for one-stop PCB assembly services. We procure high-quality electronic components based on your PCB design. Our advanced electronics assembly solutions and superior customer service support you throughout the assembly process till the PCB board is tested and shipped to your promises.

HITECH CIRCUITS turnkey PCB solutions: Contributing to every stage of PCB production

OEMs prefer to work with one-stop PCB assembly manufacturers to provide services at every production stage:

Components procurement: Careful selection and timely procurement of components are key to an efficient PCB assembly process. The HITECH CIRCUITS procurement team studies details of the PCB design and layout before placing the orders for components to avoid problems in the layout later on.

Component placement: If the electronic components are not placed correctly on a blank circuit board, it can cause problems during assembly. It may result in incorrect soldering and can even cause shorts and failures in some or all of the automated processes.

PCB board layout: The schematic layout of the circuit board is decided during the PCB design process. Design choices affect the cost and delivery schedule of PCBs. Complex PCBs require longer procurement lead times and fabrication time. Therefore, coordination with the design team is critical to meeting cost and delivery targets. A one-stop provider can keep track of all the connections or interfaces that the design may require and accommodate them in the manufacturing schedule and costs.

Testing: HITECH CIRCUITS provides comprehensive testing services for PCB components and functionality. Our powerful tests include Automated Optical Inspection (AOI), X-Ray tests, in-circuit tests, flying probe, Jtag. We will not let any board pass through unless it’s perfect!

Hitech Circuits partners with you from the PCB design phase to maximize the benefits of DFM for product development, including making the right components selection and placement decisions, and finally through to production and testing.

The advantages of using one-stop PCB assembly services

There are many advantages to using a single company like HITECH CIRCUITS for end-to-end PCB manufacturing and assembly:

Reduce PCB fabrication and assembly costs: Since our one-stop PCB services cover all processes, including fabrication and assembly, there is no need for shipping components and boards from one vendor to another. Your Bill of Materials (BOM) cost is also optimized as we efficiently source difficult-to-find and long lead-time components. With all processes under one roof, you save on production costs.

Detect errors and issues early: An end-to-end service can spot potential errors and detect potential issues very early in the PCB assembly project. This saves time and gives you a chance to modify the design and reduce wastage, resulting in substantial cost savings.

Ensure higher quality of parts and production: It is best to get a single outsourced company to manage the entire production process for quality assurance. With multiple vendors, errors at one stage may not get communicated to the next, leading to quality issues in the end product. We provide comprehensive SMT assembly services (surface mount technology) at HITECH CIRCUITS with high-quality, ISO9001-certified equipment. We constantly review our quality management system to enhance service delivery. We select only high-quality components from proven suppliers.

Maintain easy communication with a single point of contact: When you have a single point of contact, there is better collaboration between designers, engineers, and testing teams. You don’t need to circulate design files with multiple vendors—one error in a chain of vendors can cause delays and quality issues in the final assembly phase. A single point of contact makes it easy to initiate change order changes with a simple phone call or email.

Develop, test and take products to market faster: To compete in today’s fast-paced market, you need to turn your ideas into thoroughly tested and functional products in the quickest time possible. Work with a single partner for shorter procurement lead times, smoother production, and a faster time-to-market while delivering quality products to your customers. We handle all aspects of the PCB manufacturing process so you can focus on improving the performance of your final product and designing better products!
