Used DISCO DFG 840 #9243888 for sale

DISCO DFG 840 is a wafer grinding, lapping and polishing equipment designed specifically for semiconductor manufacturing. The main system consists of a precision polishing table, a grinding wheel and an adjustable lapping plate. This unit is capable of grinding, lapping and polishing wafers within defined tolerances. The polishing table of the machine is the central part and is used for controlling and limiting the movement of the wafer while being processed. It is made of stainless steel with a special coating to ensure a smooth and flat surface while grinding and lapping. The grinding wheel, made of hardened steel, is powered by a high torque motor to ensure smooth grinding and lapping operations. The adjustable lapping plate helps to adjust the polishing pressure in order to achieve the desired results. DISCO DFG840 also offers automated wafer handling capabilities for efficient and accurate production. The tool is equipped with a wafer-handling unit for loading and unloading wafers into the machine, and a robotic arm, which can perform precise grinding and lapping operations. The robotic arm can handle large nos. of wafers without the need for manual handling. The machine also features an auto-positioning unit, which provides precise and accurate alignment for each wafer surface. The asset is also equipped with a wide range of process control systems, which allow the user to monitor and optimize each process. These systems include a process monitoring camera, a grinding speed control model, and a grinding force control equipment. All of these components combine to provide an accurate and repeatable process for grinding, lapping and polishing wafers to the highest quality standards. DFG-840 is highly reliable and robust, and is designed for intense industrial usage over extended periods of time. Furthermore, it offers precise control over wafer processing, allowing for greater accuracy and increased yields. DFG 840 is an ideal choice for the production of high-quality wafers.
