Used IPEC / WESTECH / SPEEDFAM 472 #9242698 for sale

IPEC / WESTECH / SPEEDFAM 472 is a wafer grinding, lapping, and polishing equipment designed for high-precision surface finishing of semiconductor wafers. Powered by a 300-horsepower motor, IPEC 472 features a universal drive plate, which can be used with a variety of platens, including rotary grinding and lapping plates, or linear lapping and polishing plates. The system has four independent working pieces, allowing for simultaneous grinding, lapping, and polishing of multiple wafers. The unit features multiple grinding modes, including reciprocating grinding, plunge grinding, and creep feed grinding. Reciprocating grinding is used to gently grind away surface material with a fixed feed speed for superior surface finish accuracy. A plunge grinding mode allows for grinding to a specified depth. The creep feed grinding method is used for high-volume processing of large parts, providing fast stock removal while ensuring excellent surface finish. High stock removal rates can also be achieved through the use of a high-pressure coolant machine. The lapping capabilities of WESTECH 472 are enhanced by its electronic displacement tool, which continuously monitors and adjusts the pressure of the lap platen to ensure maximum surface finish accuracy. This asset can be used with electrostatic chucks for non-magnetic components or with vacuum chucks for magnetic components. The final stage of SPEEDFAM 472 is the polishing process, which uses recirculating vibratory media to achieve ultra-smooth finishes. The vibratory media is controlled by a patented servo-motion controller, which ensures maximum accuracy and reproducibility across multiple parts. The controller also features an optical emissions model, which permits detailed inspections of the wafer. 472 is the perfect solution for grinding, lapping, and polishing high-precision surfaces on semiconductor wafers. Its powerful motors, versatile grinding and lapping modes, and precise polishing capabilities make it an ideal choice for demanding applications.
