Used UNIVERSAL VISE & TOOL Swisher Mark VI #92001 for sale

UNIVERSAL VISE & TOOL Swisher Mark VI is a comprehensive wafer grinding, lapping and polishing equipment designed to satisfy the requirements for very accurate, high-precision polishing of semiconductor wafers. This system has been designed for fast, automatic, and accurate lapping and polishing of semiconductor wafers in a production environment. The Mark VI is equipped with a built in Mark VI turntable which is a closed loop programmable controller unit featuring an advanced control algorithm. This algorithm can be used to adjust the speed, acceleration, and decrease of the turntable motion to ensure precision in lapping and polishing operations. The Mark VI is unique because it has incorporated a state of the art wafer chucking machine. This tool is designed to eliminate any potential slippage or tilt during the lapping and polishing processes. The Mark VI also features a highly efficient cooling asset that is designed to maintain a constant temperature of the entire lapping surface. This ensures consistent results with repeatability and no variation in the lapping or polishing forces applied to the wafer. A specialized wafer holder is included as well, which was designed to hold the wafer securely during the entire polishing cycle, eliminating any potential for the wafer to slip or tilt during the processing cycle. Additionally, the entire model is designed for precision assembly and positioning so that it can achieve the highest level of accuracy and repeatability within the entire semiconductor wafer grinding, lapping, and polishing processing. The Mark VI is equipped with a pneumatic polishing arm that applies pressure to the wafer as required by the lapping and polishing process. The arm is adjustable to ensure the most exact pressure is applied to the wafer during the process. The lapping plate of the Mark IV has been designed to match most substrate sizes and is coated with diamond-based abrasives to ensure the highest degree of accuracy and repeatability. Finally, the Mark VI is equipped with a direct drive servo motor equipment with adjustable speeds, which allows for rapid and exact positioning of the lapping plate. This system allows for quick polishing cycles and repeatable results.
