Used DNS / DAINIPPON / SCREEN AS 2000 #293630512 for sale

DNS / DAINIPPON / SCREEN AS 2000 is a wafer grinding, lapping and polishing system specifically designed for the semiconductor industry. It utilizes abrasive grinding techniques to create the finest finish on the surface of wafers, with a very low defect rate. The system consists of five components - a grinding wheel, a multi-axis holder, a polishing unit, a control unit and a software package. The grinding wheel is designed to remove material from the surface of the wafer and achieve the desired geometry. It consists of a rotating disc with a series of abrasive particles that are maintained at a precise spacing to optimise the cutting action. The wheel is attached to the holder which moves in a multiaxis motion to provide a more accurate and controlled grinding action. Through the use of high-resolution encoders and sensors, the wheel position and speed are accurately monitored and adjusted accordingly. The polishing unit helps to further refine the surface of the wafer and reduce surface damage. The unit consists of a platform that holds the wafer and a rotating wheel that applies a predetermined pressure and polishing solution to the wafer surface. The pressure and solution are carefully selected and adjusted in order to obtain an optimal finish on the wafer. The control unit provides the user with access to various functions for setting up and controlling the grinding and polishing process. Information such as wheel position and speed, polishing pressure and solution, and grind angle can all be monitored and adjusted using the control unit. The software package is also used to provide additional data and feedback about the process. In conclusion, DNS AS 2000 wafer grinding, lapping and polishing system is a powerful tool for the semiconductor industry. It offers precise control and monitoring of the grinding and polishing process in order to obtain a high quality, defect free finish. The control unit and software package provide the user with access to a range of functions and data to ensure optimal results.
