PPO Product Stress Detection
문제 현상
[Problem Phenomenon] Lack of on-site determination means for PPO internal stress; problems are only found after flowing out
원인 분석
Internal stress cannot be judged visually and requires detection means such as solvent immersion or polarized light; immersion in ESC-sensitive media can quickly expose the stress level; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Establish a solvent immersion stress detection procedure; sample-check key parts for polarized stress; associate and trace detection results with process parameters; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PPO internal stress relies on solvent immersion detection; visual inspection will miss it; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
