Strasbaugh 7AA Backgrinder

Information: Strasbaugh 7AA The 7AA combines proven vertical down-feed grinding technology with force adaptive grinding. The 7AA lowers the diamond wheels onto the wafer limiting the total downforce that can be applied to the wafer to a predetermined maximum. This protects the machine, the diamond wheels, and your valuable product from being overstressed, yet allows the machine to grind at its maximum possible rate. The 7AA also uses closed loop thickness control to reduce thickness errors and eliminate regrinds. Through continuous monitoring the computer determines if the final thickness varies from the target thickness and adjusts the grind spindle position. The manual version uses the same grinding method and built-in measurement technologies as the automated tool. The manual tool allows for processing of non-standard shapes and substrates up to 300mm in diameter. Using templates and appropriate size wafer chucks, the 7AA manual tool supports processes for a wide range of materials as well as various shapes and sizes.
