Oil-Free Air สำหรับ Wafer Fab + SMT Line

ISO 8573-1 Class 0 + ISO 14644-1 cleanroom — ป้องกัน wafer defect, solder void, HDD head crash

Yield = Air Quality

ใน wafer fab, oil contamination แม้ trace = micro-defect = $30K-100K/wafer loss. ใน SMT solder paste, oil = solder void = field returns. ใน HDD assembly, oil = head crash. EUV lithography — oil vapor damage optics
