Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal stress failure
Cause: Overheating due to poor heat dissipation, high ambient temperatures, or excessive current draw causing solder joint fatigue, component degradation, or thermal runaway in semiconductors.
Electrical overstress (EOS) or electrostatic discharge (ESD) damage
Cause: Voltage spikes, power surges, improper grounding, or handling without ESD protection leading to immediate or latent failures in sensitive ICs, transistors, or capacitors.
Maintenance Indicators
  • Intermittent operation, erratic behavior, or unexpected resets indicating unstable power or failing components
  • Burning smell, visible discoloration (browning/charring), or bulging/leaking capacitors on the board
Engineering Tips
  • Ensure proper thermal management: Use heatsinks or forced air cooling as specified, maintain clean air filters, and avoid obstructing ventilation to prevent overheating.
  • Implement power quality protection: Use surge protectors, uninterruptible power supplies (UPS), and ensure stable input voltage within manufacturer's tolerances to prevent electrical damage.
