In recent ESD test, the result is failure.
I wonder is the following connection is the root cause:
Link the "earth GND" to the "power supply GND", the power supply GND is the GND of AC 220V, which has three pins: N , S, and power supply GND.
The contact ESD is +-6KV, ESD3.
Then after ESD test, the AC220V-to-DC5V convert is failure. And the other circuit is good.
Does this connection cause the ESD failure?
Best,
