How it works

Insert carriers utilize a replaceable insert or template around the workpiece, typically made from a compliant material, pressing the workpiece from the edges to prevent edge rounding. PR Hoffman's insert carriers use spring steel, stainless steel, hard rolled spring steel, cold rolled steel, Lamitex (fiberglass-epoxy sheet), PVC plastic, polycarbonate plastic (Lexan), vinyl, or phenolic as carrier materials. Insert carriers can be manufactured for 3 inch, 4 inch, 5 inch, 6 inch, 8 inch, and 12 inch wafer sizes using PR Hoffman's high precision laser and patented designs.[1][2]
