How to operate a PCBA factory with a good reputation?

How to operate a PCBA factory with a good reputation? Today I will share with you.
First of all, PCBA factories are countless all over the country, not even those small handicraft workshops. How difficult is it to be top-notch among so many companies and be praised by everyone? Today we have to change our thinking to analyze this problem.

From the perspective of engineering process, how to operate a PCBA factory with a good reputation? PCBA manufacturers can do everything from PCB circuit board light board, SMT chip processing, component selection, DIP plug-in post-welding, and assembly testing.

The first point: PCB circuit board light board.

There are military-grade high-frequency boards, flexible circuit boards, ceramic substrates, characteristic impedance boards, metal substrates, chemical nickel-gold boards, thick copper power boards, rigid-flex boards, and so on. Then these PCBs of different materials have their own different requirements. The most special thing is that none of the customer's requirements are the same. Therefore, to master these PCB requirements and customer needs, the most important thing is that there should be no margins. This is a difficult point. If there is a problem, all subsequent processes will cause poor quality due to a mistake in the starting point. Think about the attitude and response of the customer.

The second point: SMT patch.

The process of patch processing includes: incoming material inspection, solder paste printing, SMT patch processing, DIP plug-in post-welding, assembly testing, and first article inspection. Among them, SPI solder paste detector, online AOI, offline AOI, X-ray, first piece detector, etc. are required. In addition, any difference in the quality of the solder paste and the stability of stirring and soldering will cause the overall quality problem. If there is a quality problem, it will inevitably affect the reputation of the entire company.

The third point: the procurement and storage of components.

Components, especially humidity-sensitive components, BGAs and ICs, have very strict storage requirements for these special components. If the preservation measures are not in place, all soldered components will fail the inspection, which is not only a problem of rework, but also affects customers. The launch time of the product causes unnecessary time cost output. Then customers will inevitably exclude relevant suppliers. It is even more difficult to get a good reputation than to climb Mount Everest.
