Lapping & Polishing Carriers

Precision carriers for double-sided lapping and polishing of wafers, glass, sapphire and ceramic substrates.

Product Overview

Our lapping and polishing carriers are engineered for double-sided lapping and polishing processes. The carrier ring design protects wafer edges from chipping while improving TTV and TIR performance. We offer both insert carriers and mounted carriers across a wide range of materials and dimensions to meet diverse processing requirements.
