316 Stainless Steel Super Air Knives Dry Silicon Wafers
A silicon wafer manufacturer needed to dry the wafers off before they went to a subsequent process. The wafers are 12" in diameter, and 0.325" thick. The standing water on the surface will dry and cause defects because of water spots. The solution was to install two Model 110212SS-316 12" (305mm) 316 Stainless Steel Super Air Knife Kits to blow off both sides as the wafers are transferred from one belt to another on the conveyance line. The customer was able to get good results at 40 psig inlet pressure to the knives and reduce the defect rate considerably.
