Metallographic grinding and polishing insight Struers

The basic process of mechanical specimen preparation is material removal, using abrasive particles in successively finer steps to remove material from the surface until the required result is achieved. There are three mechanisms for removing material grinding, polishing, and lapping.

Wafer backgrinding

Prior to grinding, wafers are commonly laminated with UV curable back grinding tape, which ensures against wafer surface damage during back grinding and prevents wafer surface contamination caused by infiltration of grinding fluid and/or debris. The wafers are also washed with deionized water throughout the process, which helps prevent contamination.
