Rear power distribution copper plane short

During testing of the power distribution board, it is noticed that the power supply input plane is shorted with the ground plane. The reason are likely because when unplugging the connector it deformed the copper plane, therefore shorting them. The root of the cause is that the Molex micro-fit lack a separate mechanical relief pin, so when unplugging the connector all the stress are concentrated on the trace/plane and damaging them.

Solution:

Find Microfit with separate mechanical support pins or another connector.
