Lapping is a final abrasive finishing operation that produces extreme dimensional accuracy, corrects minor imperfections of shape, refines surface finish and produces close fit between mating surfaces ...
Description: Flat Lapping, (free abrasive machining). The objectives in lapping are to obtain part flatness, parallelism, dimensional accuracy and quality surface finish. Of the four surface finishes ...
During lapping, a spinning abrasive surface is used to thin wafers from the backside. As the process progresses, precise feedback is required to monitor the amount of material removed and determine ...
