Microcircuit ESD Damage

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.

Reference :
NASA-STD-8739.7 paragraph 7.2
Protected Work Environment
3. ESD-Protective Work Surfaces - All work surfaces in an ESD-protected area shall be static dissipative and electrically connected to the common point ground.
5. Personnel Grounding Devices - Personnel Grounding Devices shall be supplied to all personnel working with or handling ESDS items to prevent the accumulation of dangerous electrostatic charge levels.
