The PCBA control board process is more complicated, and any problem in any part will cause welding quality problems. Therefore, professional management specifications are required in the processing.
1. "Air Shower Room Regulations", wear electrostatic coats according to the specifications. When starting the air shower, please turn the body according to the prompts and enter the air shower room. The maximum number of people can not exceed 4 at a time.
2, factory 7S management, workshop temperature should be: 18-26 ° C humidity: 35-75%, to be sorted, rectified, cleaned, cleaned, literate, safe and economical.
3, solder paste management specifications: solder paste storage refrigeration temperature 0 ° C
Second, PCBA control board static management standard, PCBA control board static management, equipment grounding, through the connection of metal wire and grounding device; wear electrostatic clothing, static shoes, electrostatic bracelet; detection of electrostatic clothing and static shoes through ESD test Clean all static electricity sources in the work area so that they are at least 750px away from the ESD sensitive components.
Third, the PCBA control board cleaning standard, the bad PCB must be cleaned within one hour; in the cleaning area to clean the PCB, the PCB to be cleaned should be separated from the cleaned PCB; to ensure that the pinholes, screw holes and other locations are clean.
