Precision Ceramic Bond Diamond Grinding Wheel / Wafer Thinning Wheel – for Silicon Wafer Polishing & Back Grinding

Product Name:

Ceramic Bond Diamond Wafer Thinning & Polishing Wheel (for Silicon Wafer Processing)

Key Specifications:

Product Description:

This precision ceramic bond diamond grinding wheel is specifically designed for silicon wafer back grinding, thinning, and polishing – critical processes in semiconductor manufacturing.

Unlike resin or metal bond wheels, the ceramic (vitrified) bond provides:

• Excellent self-sharpening performance – fresh diamond continuously exposed

• High strength and wear resistance – long wheel life

• Good porosity – efficient chip removal and heat dissipation

• Superior form-holding – maintains flatness and geometry

The ceramic bond structure creates a porous network that allows for:

• Cool grinding – low grinding temperature, prevents wafer damage

• Sharp cutting action – high grinding efficiency

• Reduced subsurface damage – critical for wafer integrity

Typical applications include:

• ✅ Silicon wafer back thinning (back grinding)

• ✅ Wafer polishing and surface finishing

• ✅ Semiconductor substrate preparation

• ✅ LED substrate processing (sapphire, SiC, GaN)

Why Ceramic Bond for Silicon Wafer Grinding?

The ceramic bond is the preferred choice for rough and semi-finish grinding of silicon wafers, offering an optimal balance of material removal rate and surface quality.
