2. Components:  C2 MOS capacitor ESD damage

Here are two images showing ESD damage to a C2 MOS capacitor. What appears to be a slight pinhole on the top image shows to be substantial damage to the trace when examined at 4300X. .

This damage could have been prevented had the appropriate ESD safe-guards been in place.
