PCBA patch processing need to pay attention to what?

The process of PCBA production involves several stages, such as PCB board manufacturing, electronic component procurement, and inspection, SMT chip production and processing, plug-in production and processing, program firing, testing, and aging. The supply and manufacturing chains are long, and any defects in any of the stages can lead to mass quality failure of the PCBA board with serious consequences. Therefore, PCBA patch processing quality control is crucial to ensure high-quality electronic processing.

To achieve this, holding a pre-production meeting after receiving the PCBA patch production and processing order is important. The meeting is mainly for process analysis of PCB Gerber files and to submit manufacturability reports (DFM) according to different customer needs. This step is often overlooked by small manufacturers which can lead to poor quality and rework.

In addition, it's essential to strictly control the procurement channels of electronic components by obtaining goods from large traders and original manufacturers to avoid using second-hand materials and counterfeit materials. Also, setting up a special PCBA incoming material inspection post to inspect the components is necessary to ensure that they are fault-free.

Solder paste printing and reflow oven temperature control systems are the key assembly points, and laser stencils with higher quality requirements are needed to meet production and processing requirements. The temperature control of the reflow oven is essential for the wetting of the solder paste and the firmness of the steel mesh.

In the plug-in process, the mold design for wave soldering is crucial, and engineers must practice and summarize to maximize the yield rate.

For orders with PCBA test requirements, it's necessary to perform ICT (circuit test), FCT (functional test), burn test (aging test), temperature and humidity test, drop test, etc. Performing strict implementation of the AOI test can significantly reduce the defects caused by human factors.
