Many companies can easily get ISO9001 certification. However, the certificate doesn't mean that the company's internal management system conforms to specifications.

The scope of ISO9001's quality management system is relatively broad, hundreds or even thousands of fourth-order documents need to be established. This requires us to focus on the big and the small both, starting from examining the key quality points in the PCBA processing step.

In the SMT process, steel mesh, solder paste, solder paste printing, refueling, reflow oven temperature, baking, AOI inspection and static electricity are the core quality points. In the DIP process, the pre-furnace QC, wave soldering temperature, and FCT function test are the key points. Our quality management needs to be carried out around these core points.

The established quality management system documents include equipment operation guidelines, repair and maintenance manuals, checklists, and equipment calibration. SOP operating specifications, record sheets, etc. at key process points. After the establishment of a complete PCBA processing process form system, it is actively implemented within the company. This requires managers to constantly check the line online during daily operations to check the form: whether it is effectively implemented, because employees will only complete what you have done. Check the work.

The manufacturing process of PCBA electronic manufacturing enterprises is more complicated and the process is longer. Whether to implement the quality management system is the strategic determination of the top management, and whether they are willing to exchange the current cost for the future quality and efficiency.
