ESD Protection Zone
When the ESD-sensitive whole machine is subjected to high and low temperature test or aging test, the electrostatic field test of the work site and the high and low temperature box must be carried out first, and the potential cannot exceed the safety value. Otherwise, the static elimination process should be performed.
Anti-static measures should also be taken when the welded printed circuit board is to be treated as three. Do not use general brushing, ultrasonic cleaning or spray cleaning.
Low-impedance instruments and equipment (such as signals, bridges, etc.) used during commissioning, measurement, and inspection should be connected to the input of the ESD-sensitive device after the ESD-sensitive device is connected to the power supply.
In the production line of ESD sensitive test equipment, the electrostatic potential test should be strictly used to monitor the change of electrostatic potential, so as to take static electricity in time.
