Many cleanrooms keep two wipe grades: one for critical surfaces, one for everything else. The cost difference can be large. But overspecifying for noncritical areas wastes money. Under‑specifying for critical areas causes defects. We built a decision matrix based on real fab data. Product pair comparison – four models Property Microfiber A Microfiber B Polyester […]

Photomasks and wafers are the most contamination‑sensitive surfaces in semiconductor fabrication. A single particle of 0.5 µm on a photomask can print a repeating defect across thousands of die. Standard wipes (even 180 g/m² ultrasonic) are not certified for sub‑micron cleanliness. Two sub‑micron series from BN Series Part numbers Grammage Edge Pack sizes Particles (≥0.5
