How important is ESD electrostatic protection during PCBA processing?
There are many precision electronic components on the PCBA board, and many components are more sensitive to voltage. Shocks above the rated voltage can damage these components. It is difficult to check the PCBA board damaged by static electricity step by step during functional testing. What is even more deadly is that some PCBA boards function normally during testing, but when the finished product is used in the hands of customers, occasional defects occur, which brings great hidden dangers to after-sales and affects the company's brand and goodwill. Therefore, in the process of PCBA processing, we must attach great importance to ESD electrostatic protection.
The method of PCBA processing to strictly control ESD electrostatic protection is roughly as follows:
●To ensure that the temperature and humidity of the workshop are within the standard range, 22-28 degrees Celsius, humidity 40%-70%
●All employees must discharge static electricity when entering and leaving the workshop
● Dress as required, wear electrostatic caps, electrostatic clothing and electrostatic shoes
●All stations that need to touch the PCBA board must wear a corded electrostatic ring, and connect the corded electrostatic ring to the electrostatic alarm
The electrostatic wire is separated from the equipment ground wire to prevent equipment leakage and damage to the PCBA board
●All turnover car electrostatic frame shelves, etc. must be connected to the electrostatic ground wire
●Strictly follow the ISO quality management requirements to carry out ESD static inspection
