How to select a PCBA manufacturer

Some customers and engineers do not know how to select a PCBA manufacturer that is qualified and suitable for them. After all, PCBA is a very complex and professional process, from communication in the early stage, to procurement, to production, to the final assembly of the finished product, if not a professional, rigorous, and experienced team is prone to occur problems in various links, resulting in poor final production results. Therefore, when we select PCBA processing manufacturers, we must pay attention to the following tips:

How to select a PCBA processing manufacturer

1. The degree of factory specialization
First of all, it depends on whether the factory has professional equipment. PCBA processing and production require very professional equipment, such as high-speed placement machines, multi-temperature reflow soldering oven, AOI testers, ICT online testers and other equipment, which are the basis of production. Secondly, we need to check whether there is professional process management, PCBA processing requires professional equipment and professional process management to control quality. Generally, good PCBA processing manufacturers will pass ISO9001, ISO14001, OHSAS18001 quality management system, IPC-A-610E, IPC-A-610C CH, IPC610 electronic assembly acceptance standards and other certifications, whether there are SOP job instructions and other documents to instruct on employee behavior. By looking at the factory's documentation, qualification certification, work instructions, employee training and other materials, you can roughly know the strength of the factory's quality control.

2. Service consciousness
What PCBA factory does is not only products, but more services, processing services, pre-sales and after-sales services. A PCBA prototype manufacturer with a good sense of service can take the initiative to take responsibility and respond quickly to customers when they encounter problems. Therefore, the service awareness of a PCBA prototype manufacturer is very important. The service awareness of PCBA prototype manufacturers can be known by understanding the company's corporate culture and the attitude of the business personnel to customers.

3. Industry experience
Under the general environment of the Sino-US trade war, the PCBA industry is experiencing a great sorting-out process. Some poorly managed PCBA processing manufacturers have begun to close down one after another. Having many years of industry experience reflects the strength of a PCBA manufacturer to a certain extent. Secondly, it depends on whether the manufactured product is high-end, mid- end or low-end, and for which field of product is manufactured. And these are used to judge whether it matches with customers. Only the right one is the best.

4. Price
In the market, the price of PCBA prototype is relatively transparent. There are high prices and low prices, but it is not that the lower the price, the better. Some PCBA processing manufacturers choose to purchase components from formal channels and implement strict quality control, which will increase the cost of processing; while some PCBA processing manufacturers may easily source components from unauthorized channels in order to reduce prices, resulting in unstable quality. As the saying goes, you get what you pay for, so, we should select a suitable PCBA processing manufacturer with high cost performance according to our own situation.
