Lapping and Polishing Basics
grinding process must be a balance of material removal and subsurface damage. In many cases it is advisable to initially cut the specimen with a gentle mechanical method such as a wire saw. A properly prepared wire saw cut sample can eliminate the grinding process altogether. : Lapping Lapping is the removal of material to produce a smooth, flat, unpolished surface. Lapping processes are ...

New Product: "BGM300" TSV Back Grinding Process ...
· If grinding is insufficient, on the other hand, the subsequent etching process will become long and costly. To avoid these problems, TSV depths need to be accurately measured prior to grinding. BGM300 can make speedy measurement of TSV depths and silicon thicknesses, which are essential for proper grinding. BGM300 can also measure remaining silicon thickness (RST) over TSVs after grinding.

Grinding and Polishing Guide | Buehler
During the lapping process, the disc is charged with small amounts of a hard abrasive such as diamond or silicon carbide. Lapping discs can be made of many different materials; cast iron and plastic are used most commonly. Lapping produces a flatter specimen surface than grinding, but it does not remove metal in the same manner as grinding. Some platens, referred to as laps, are charged with ...

Silica Sand Processing Sand Washing Plant Equipment
· DRYING AND DRY GRINDING. In plants where silica flour is to be produced, drying is often necessary. Drying is done in rotary, oil or gas fired dryers. Dry grinding to minus 100 or minus 200 mesh is done in Mills with silica or ceramic lining and using flint pebbles or high density ceramic or porcelain balls. This avoids any iron contamination from the grinding media. In some cases it may be ...
