Used K&S 971 #9146108 for sale

K&S 971 is a wafer and mask scrubber manufactured by K&S Corporation, designed for large-scale semiconductor production. The scrubber is designed to quickly clean and polish silicon wafers, and photomask plates used in photolithography. The scrubber can utilize different methods of cleaning including lapping, chemical etching and mechanical scrubbing. 971 scrubber has a strong and durable aluminum frame with stainless steel grids and seals, designed to withstand frequent cleaning in harsh industrial conditions. The wafer and mask scrubber processes up to 12" (30.5 cm) round silicon wafers and 8- or 12-inch (20- or 30.5-cm) photomask plates. It works by using an abrasive lapping paste applied to both sides of the wafer or maskplate. The lapping process allows for smooth, uniform cleaning. K&S 971 scrubber also has a uniquely designed clipping system that provides ample pressure to ensure complete cleaning. The scrubber uses an eight step process with four different settings for lapping pressure, ensuring maximum efficiency and optimal quality of clean. The scrubber offers adjustable cleaning speed, allowing it to process wafers of any size and thickness. The scrubber features an intuitive control panel, allowing operators to quickly set up and run the device. The dielectric, polymer-based paddle designs reduce noise and static electricity. They also act to cushion the fragile wafers and maskplates during lapping. 971 scrubber can be used with a variety of different types of lapping fluids and abrasives for custom cleaning applications. It can be used with both chemical and mechanical scrubbing, allowing users the ability to use the right scrubbing technique for their particular application. The scrubber also utilizes high temperature drying, which helps to remove moisture from the wafers and mask plates before lapping. K&S 971 scrubber is an efficient tool for performing quick, high-quality cleaning on large-scale semiconductor products.
