Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
LED Encapsulant Dispensing Nozzle Clogging
Cause: Accumulation of cured or semi-cured encapsulant material due to improper cleaning cycles, material contamination, or extended idle periods without purging.
Precision Positioning System Drift/Inaccuracy
Cause: Wear or contamination of linear guides/ball screws, thermal expansion of mechanical components due to inadequate environmental control, or degradation of encoder feedback signals.
Maintenance Indicators
  • Visible inconsistency in LED dome shape or size during encapsulation, indicating potential nozzle issues or pressure fluctuations.
  • Audible grinding, clicking, or irregular servo motor sounds from the positioning axes, suggesting mechanical wear or misalignment.
Engineering Tips
  • Implement a strict preventive maintenance schedule for the dispensing system, including regular nozzle inspection/cleaning and verification of material viscosity and pot life to prevent curing in the lines.
  • Maintain a controlled environment with stable temperature and low particulate levels, and perform regular laser alignment checks and backlash compensation on the positioning system to ensure micron-level accuracy.
