Semiconductor Wafer Processing Tape SWT 10T+R
Wafer processing tape designed for semiconductor dicing processes.
Nitto Semiconductor Wafer Tape SWT 10T+R is designed for semiconductor dicing processes. This product consists of a clear transparent PVC film coated with a pressure sensitive acrylicbased adhesive manufactured in clean room environment. For easy unwind, the backing of the PVC-film is coated with a silicone release. The product is wound on a plastic core. Rolls are individually packed in a double polyethylene anti-static bag and foreseen with lot number.
