1. The whole machine without shell uses anti-static packaging bag. Regularly inspect anti-static tools, settings and materials to confirm that they are in the required conditions.
2. When assembling the finished product, follow the procedure below:
Warehouse → production line → production line upgrade software → assembly into a complete machine → QC test → write IMEI number → QA full inspection → restore factory settings → warehouse (station settings may vary depending on the model, depending on customer projects or Engineering guidance) If you need to upgrade the software before assembling, you cannot assemble it into a finished machine and then upgrade the software. It may be impossible to upgrade due to improper soldering, short-circuit, work process problems, etc., and the assembly factory misjudged that the PCBA is bad.
The PCBA production process requires very important electrostatic protection to effectively improve the yield of the PCBA board.
