COC Electrical Performance Test Fluctuation
문제 현상
The dielectric constant and loss tests of COC capacitor films and insulating parts fluctuate between batches, and the high-frequency performance does not meet the design requirements.
원인 분석
COC electrical properties are sensitive to molecular orientation and crystalline state (amorphous uniformity); processing stress and thickness fluctuations affect dielectric consistency; trace impurities change the dielectric loss.
해결 방법
①Stabilize the extrusion and stretching processes to ensure consistent thickness and orientation; ②use a low-stress process to reduce dielectric fluctuations; ③control raw material purity; ④perform correlation analysis between batch sampling of electrical properties and process parameters.
핵심 요약
COC electrical performance consistency is a mirror of process stability; thickness and orientation control is the core of film parts; dielectric sampling data drives process improvement.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
