How to find the right PCB assembly company

Nowadays, you could easily find countless PCB assembly (PCBA) factories on the Internet and there will be thousands of websites showcasing turnkey PCB Assembly factories occupying your screen. Although many of the manufacturers do show their production capabilities and production lines, among so many options, it still is not very easy to choose a reliable overseas PCBA manufacturer, especially without visitation and regular production supervision.

Even before entering the PCB production stage, it is important to make sure that PCB production is in the safe hands of reliable PCBA suppliers. In addition, it is necessary to have clear goals and many questions may come up, such as: do we need to do quick prototyping or do we need to proceed with regular mass production? Are we pursuing a shorter delivery time or better quality? Do we care most about the cost or the services offered?

It is not an easy task to choose the right PCBA manufacturer and for this purpose, there is a need of doing in-depth research regarding PCBA manufacturers, which will hopefully then assist you to get the best PCBA and eventually, a much better overall result. 

To make this research process easier, FS Tech’s page on ordering assistance comes up with certain effective points that will help in choosing the best PCBA supplier to hire for PCBA. 

Find a PCBA company

Choose a large-scale PCBA factory

To achieve high-quality PCBA manufacturing, advanced equipment and a large enough factory to handle large-scale product manufacturing is necessary. A professional turnkey PCB company must have a complete production line. In terms of assembly capabilities, manufacturers need to have specialized assembly equipment such as solder paste printing machines, high-speed Pick & Place machines, reflow soldering, and wave soldering machines. In terms of quality control, they need to be able to provide complete PCB testing services and have AOI inspection equipment, ICT online testing equipment, X-RAY testing equipment, etc. Choosing a company with professional production records will help ensure that your project is produced at the highest quality. Large-scale PCBA factories commonly have many related production record documentation on their website, which typically details a variety of PCB quality management methods. This means that as a customer, you could use these documents to examine their professionalism according to their production records before proceeding with using their services.

PCBA Qualification Certification

Reviewing the qualifications of a PCB assembly company is an essential step. You need to confirm that the factory is ISO9001 certified and that its acceptance criteria follow IPC-A-610F. Are there complete quality manuals and SOPs to guide employees in their production work? Here at FS Technology, we are verified by ISO9001, ISO14001, ISO13485, and IATF 16949 quality standards and we strictly follow IPC-A-610F acceptance for our finished PCBA. Plus, FS Tech establishes and strictly implements SOP production specifications as the level of our PCB quality control management is higher than the industry standard. Below is our certificate presentation:

PCB board Manufacturing Capability Matching

High-quality PCBA boards require high-quality PCBs and PCB assemblies. Even if it requires a higher price, it is recommended that you consider it and never conciliate with the quality of PCBs. Price should only be an option and not a deciding factor as a more expensive PCB can be beneficial in the long run. Therefore, the first thing to pay attention to is the quality of the product provided by the PCB manufacturer and quality assurance can help to track down whether the PCBA quality is on track. As a summary, you should consider the following properties before proceeding with a service or manufacturer:

Thus, it is critical to ensure that manufacturers use the best available raw material and processes to produce a grade-A quality PCBA board. While every service provider claims to provide a high-quality product, there is a need to identify the truth behind that statement. It can be done by carefully examining the various characteristics of a PCB, such as hole position, hole size, trace width, component spacing, vias, and copper thickness. 

PCBA Manufacturing Capability Matching

FS Technology has always advised our clients to clarify their project needs before starting to look for an assembly service provider. Matching the corresponding service providers through demand can not only reduce your project costs, but also make cooperation with each other smoother. So the first question in selecting the best match for a PCBA service provider is, whether this specific manufacturer is capable of doing what is required for PCBA or if the manufacturer shows some  incapabilities. For this you need to consider the following questions:

  • What is included in the services provided
  • Best conductor used in conductive layers of PCB 
  • Whether it meets the requirements of multi-layer boards
  • Minimum assembly package
  • Circuit Board Sourcing Capability
  • Whether it has the capability of SMT assembly from prototype to mass production
  • Can it satisfy manual and automatic DIP assembly at the same time?

It is worth spending time checking the checklist to make sure that the selected manufacturer meets all of them.

Options for Customization

Sometimes, extra customization is required in manufacturing PCBA as all the available options may not be enough to satisfy the needs of the customer. That additional customization may include the number of layers, colour of the solder mask, design type, and material(s) used. Hence, it is important to choose an appropriate PCBA manufacturer that allows for the right extent of customization to your project, rather than a pre-defined design.  

Co-operative PCBA Manufacturer

Choose a PCBA company with core competitive advantages

A company’s ability to collaborate and build relationships with others is another deciding factor in selecting the best PCBA manufacturer. Although technical experience matters, no one wants to work with PCB assembly manufacturers that do not prioritize customer cooperation. A cooperative relationship between customers and the manufacturer helps in finding solutions to problems more quickly and easily. Resultantly, this can help both parties to interact with each other, which in this way becomes beneficial in improving productivity and company operations/logistics. 

Excellent service awareness

If you are not sure how to choose the right PCB assembly manufacturer, you can try FS Technology. A manufacturer with just advanced and decent production equipment should not be the only standard when selecting a reliable PCBA manufacturer partner. A required professional project manager to follow up on your orders should be another factor that you consider. We should be able to listen and fully understand all of your requirements and be able to offer quick solutions for various emergencies. As a customer, you should get to know their service awareness by knowing their enterprise culture and their corporate attitude. 

Meeting Timelines

Time is precious and can’t be brought back. Sometimes, wasting time is also considered wasting money. Therefore, it is important to look for PCBA manufacturers whose track records are at the highest level in terms of in-time deliveries or even on-time deliveries. As a professional manufacturer, it simply is not good practice to not meet project timelines and delay all pre-planned processes. Furthermore, the pressure of meeting timelines should not mean compromising on quality. Consequently, it is of utmost importance to select a PCBA manufacturer that maintains an optimal track record of meeting timelines by abiding by time constraints, while also delivering the best quality product.

Final Testing

A key factor that differentiates between the best PCB and PCBA manufacturers and others is whether or not they offer high-level testing after PCB fabrication. This vital testing stage ensures that the final product is as per design requirements and is produced to top quality before it is sent out to customers. In selecting a PCBA manufacturer, keeping this as a priority may help you to design an error-free and perfect PCBA.

After Sale Service

FS Technology after-sales service

Top PCB/PCBA manufacturers will offer after-sale services to customers as not only is purchasing PCBA enough, but all of the support & services that a customer may require are very important. This is simply because no one wants to hire another expert to make some amendments to designs or to repair and replace PCBs after production. It is always best practice to hire a manufacturer who sustains an excellent track record of providing after-sale services to clients and in addition, has extensive customer support. If you are looking for a manufacturer which can provide these services, choosing FS Technology will be the correct choice for you. We provide a full range of services from procurement to delivery. Even if there is a problem with the quality of the product, we will never shirk our responsibility to customers.

Choose an experienced PCBA company

As it is understood that different PCBA manufacturer companies have different levels of expertise, it is common that everyone will always opt for an experienced PCBA manufacturer in contrary to a fresher, especially when there is a need for complex PCBs and PCBA.

Choose a PCBA company with core competitive advantages

There is fierce competition in the PCBA industry and as a manufacturer, it is difficult to survive if a factory lacks strength and core competitiveness. For example, some PCBA manufacturers have more experience in fabricating double-layer PCBs or mounting SMD components but at the same time, those manufacturers may not fit well for multilayer PCBs. When applying this concept to the level of customers, if your PCBA requires multilayer PCBs, it will be a brighter idea to opt for a manufacturer that already has experience in fabricating multilayer PCBs, even if that manufacturer may cost you a little more than the fresher. 

Overall, it is principal to ensure that, from an initial stage, your chosen manufacturer has the expertise which will match your final PCBA requirements. You could judge if the factory will meet your demands by checking its establishment year and the coverage of product industries, as well as the complexity of their assembly products. Choosing the one with more experience and a history of similarly-produced products in your field may result in higher reliability for cooperation.

Judging the company's experience with an intelligent management system

Measure PCBA price and quality

Consider the quality or price of the PCB

No matter the size of your company, when you are finding a reliable PCBA supplier, price and product quality will definitely be considered. Cost becomes a deciding factor in selecting a particular PCBA manufacturer because whether the PCBA is small or large, it still is important to obtain economies of scale, to remain profitable and efficient. Low costs in manufacturing result in more profit, however, reducing costs does not mean reducing the quality of PCBA. PCB assembly cost is relatively transparent and different factories will have different prices so you should be alert if a manufacturer quotes you an unusually low price. Contrary to the old days when customers will have to wait for weeks to get quotations for PCBA from manufacturers, nowadays, getting quotations is a matter of some minutes. This is only possible because of modern cloud computing and online pricing techniques but nonetheless, maintaining a balance between cost and the quality of PCBA to remain profitable is still critical. Even though most customers may already be aware, there are still customers who will regard price as the first reference factor when choosing a manufacturer. This can ultimately lead to some low-level, unwanted errors on their boards. In any case, choosing a well-known turnkey PCB assembly company should be the first and right choice. Most of the time, they will perform strict quality control and assurance steps, which is well worth the higher cost.


Complex PCBA manufacturing is certainly not easy for any company available in the market. Due to this, it is necessary to find the best-suited PCB assembly manufacturer that meets your needs & requirements in order to design a perfect, efficient, and profitable PCBA. Various PCBA manufacturers will offer different levels of capabilities, different levels of services, and different levels of expertise. When choosing a PCBA manufacturer, keeping all the above-mentioned points in mind truly helps in finding the best match for your PCBA manufacturing.
