Used STRASBAUGH 7AA #293634880 for sale

STRASBAUGH 7AA is a wet processing equipment designed to grind, lap and polish semiconductor wafers. The system uses a modified friction grinding process to accurately generate the desired shape, size and surface finish of the wafer material. In operation, the wafers are immersed in a bath of synthetic oil and abrasive slurry slurry and held between two rotating grinding heads. The grinding heads slowly rotate as the wafer spins, slowly grinding and abrading away material to the desired specifications. The unit is capable of processing up to four wafers simultaneously, in a single process cycle. An automated programmable controller allows the operator to precisely scale the speed, abrasive grade and depth of the process. A closed loop control machine monitors and maintains the repeatability and accuracy of the grinding operation. The tool includes two grinding chambers, two grinding pads and two plunge pads. The grinding pads are used for coarse grinding operations, while the plunge pads are used for fine grinding and polishing. The wafers can be loaded in either chamber and both can operate independently of each other. STRASBAUGH 7 AA asset is designed to be used in a hazardous environment, where it can be operated safely by trained personnel. It features a sealed design, along with an integrated water cooling model to keep the process environment under control. The unit also features an open access design, allowing the operator to easily monitor the grinding process. The equipment also features a digital readout, that displays information such as the current speed and pressure settings, the type of grinding being performed and the stage of the process. It also allows the operator to fine tune the process, in order to achieve the desired results. In summary, 7AA is a versatile and highly precise wafer grinding, lapping and polishing system. It can process up to four wafers simultaneously and provides the operator with precise control and monitoring of the process. It is designed for use in hazardous environments and can be operated safely by trained personnel.
