Vitrified bond suitable for silicon wafer back grinding wheel

Vitrified bond diamond grinding wheel bond agent has higher strength; good wear resistance, sharp cutting Grinding efficiency is high, and easy to trim; generally suitable for silicon wafers, such as rough grinding, semi-finishing grinding, etc.

The diamond grinding wheel has good self-sharpening performance and is not easy to clog; the grinding efficiency is high, the grinding force is small, and the grinding temperature is low The bonding agent itself has good elasticity and polishing performance; the workpiece has high surface finish and good surface quality; it is suitable for fine grinding and polishing of silicon wafers.

The Specification Of Diamond Back Grinding Wheels:

silicon wafer back grinding wheel features:

1, surface quality: require grinding lines evenly, without chipping, debris, scribe, etc.;

2, processing accuracy: TTV <5 μm etc. (Total thinning veracity);

3, processing quality: surface roughness: < 10 nm; damage layer thickness: < 10 μm;

Application of back grinding wheel

The grinding wheels for LED substrate are mainly used for back thinning of sapphire epitaxial wafer, silicon wafer, gallium arsenide and GaN wafer.

Workpiece processed: sapphire epitaxial wafer, silicon wafer, gallium arsenide and GaN wafer.

Material of workpiece: synthetic sapphire, single crystal silicon, gallium arsenide and GaN materials.
