PVDF High-Purity Applications Prohibit Oil-Based Cutting Fluid
문제 현상
【Problem phenomenon】Oil contamination on the surface of semiconductor PVDF parts after machining is difficult to remove, contaminating subsequent assembly
원인 분석
Oil-based cutting fluid residue is a serious contamination source for semiconductor and high-purity applications; even though PVDF is compatible with mineral oil, it is difficult to clean thoroughly; CS-Seal explicitly prohibits oil-based cutting fluid for such applications
해결 방법
Switch to compressed air or water-soluble cutting fluid for high-purity applications; verify surface cleanliness according to cleaning procedures after machining; isolate the production line from oil-contaminated equipment; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Oil-based fluid is prohibited for high-purity PVDF parts; clean machining starts from cutting fluid selection; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
