There are many precision electronic components on the PCBA board, and many components are sensitive to voltage. Shocks higher than the rated voltage will damage these components. PCBA boards damaged by static electricity are difficult to check step by step during functional testing. What's more deadly is that some PCBA boards function normally during testing, but when the finished product is used in the hands of customers, there are occasional defects, which brings great hidden dangers to after-sales and affects the company's brand and goodwill. Therefore, in the PCBA processing process, we must attach great importance to ESD protection.
PCBA processing methods to strictly control ESD electrostatic protection are roughly as follows:
Ensure that the temperature and humidity of the workshop are within the standard range, 22-28 degrees Celsius, and humidity 40%-70%
All employees must discharge static electricity when entering and leaving the workshop
Dress as required, wear static caps, static clothes, and static shoes
All workstations that need to touch the PCBA board must wear a rope static ring, and connect the rope static ring to the static alarm
The static wire is separated from the equipment ground to prevent leakage of the equipment and damage to the PCBA board
All turnover carts, racks, racks, etc. must be connected to the electrostatic ground wire
Conduct ESD static inspection in strict accordance with ISO quality management requirements
