Execution Flow

  1. Define environment, current path, signal path, and lifecycle conditions.
  2. Align connector structure and harness routing with assembly reality.
  3. Validate pilot performance before scale-up commitment.
  4. Release by checkpoint evidence, not by generic description.

Critical Control Points

  • Pin insertion force
  • Mating-gap verification
  • Molding completeness
  • Lock depth
  • O-ring compression state
  • Terminal contact resistance
  • Pressure / insulation / withstand checks
  • Cut length
  • Strip length
  • Conductor condition
  • Color / sequence consistency
  • Crimp quality
  • Solder quality
  • Electrical validation
  • Batch archive and release logic
  • Abnormal isolation + CAPA + re-verification

What This Means for Your Project

  • Shorter qualification cycles for OEM teams.
  • Clearer risk visibility before purchase decisions.
