Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal degradation
Cause: Overheating due to poor ventilation, dust accumulation, or excessive ambient temperature causing solder joint fatigue and component failure.
Electrostatic discharge (ESD) damage
Cause: Improper handling during installation or maintenance, leading to latent or catastrophic failure of sensitive semiconductor components.
