In sensitive manufacturing, many costly defects do not begin with machine failure or operator error. They begin with static charge, airborne particles, micro-scratches, adhesive residue, and unnoticed surface contamination. These issues are often underestimated because they appear as scattered defects rather than one major failure. Yet in electronics, optics, display processing, and coated surface production, even small flaws can reduce yield, increase rework, slow inspection, and weaken final product quality.
