Hi, 

The FAR process need to go through technical investigation first. 

Could you please explain what is the details of the pin leakage? 

1. How many seeing same issue out of how many produced

2. Methods of leakage measurement

We have only 1 pc failed and need to be return for FA.

 

The failure was confirm by our tester and becnch testing . 

All FAULT signals connected with pinU4 of IC U5c, Measurement voltage has found 1.8 V leakage voltage always send out from IC U5 (CPU)  We could suspect that the root cause may came from IC U5 on Eigen PCBA was damaged from.

Measured pin G of Q32 compare with the known good PBCA

  • no any fault measured = 0V and
  • fault measured = 3.3V

Measured Failed PBCA always found leakage voltage 1.38V input triggering from the Eigen PCBA even if the PCBA has no any fault.

 

Could you please provide us the ship to address? then, we can return this ssupect part to you for further investigation.
