Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Probe Tip Wear/Damage
Cause: Repeated mechanical contact with wafer pads during testing causes abrasive wear, tip deformation, or contamination buildup, leading to poor electrical contact and inaccurate measurements.
Interface Contamination/Debris Accumulation
Cause: Environmental particles, wafer residues, or oxidation products accumulate on probe tips or contact surfaces, increasing contact resistance and causing signal degradation or intermittent failures.
Maintenance Indicators
  • Increased electrical resistance or unstable contact resistance readings during testing
  • Visible debris, discoloration, or physical damage on probe tips under magnification
Engineering Tips
  • Implement regular automated cleaning cycles with appropriate solvents and dry air/nitrogen purges to prevent contamination buildup without damaging delicate probe structures
  • Establish preventive maintenance schedules for probe tip reconditioning/replacement based on usage cycles rather than failure events, and maintain controlled cleanroom environmental conditions (temperature, humidity, particulate levels)
