Semiconductor Industry
Used for thinning silicon wafers, silicon carbide substrates, etc., providing high-quality bases for subsequent chip manufacturing processes.

Optoelectronics Industry
Suitable for grinding and thinning optical materials like sapphire glass and crystal, applied in manufacturing smartphone screens, optical lenses, LED substrates, etc.

Other Fields
Also applicable to surface grinding and thinning of ceramic wafers, metal materials, etc., with wide use in electronics, machinery, aerospace, and other industries.

High Grinding Efficiency
The diamond grains in the thinning pad have strong hardness and cutting ability, rapidly removing materials for efficient thinning. For example, in grinding hard and brittle materials like sapphire substrates or ceramic wafers, it significantly shortens processing time compared to ordinary abrasive pads.

High-Precision Grinding
Enables precise thickness control and surface flatness with minimal thickness variation, meeting high-precision process requirements for materials such as semiconductor silicon wafers and optical crystals.

Excellent Chip Removal Performance
Typically designed with chip removal grooves to facilitate the discharge of grinding debris, preventing accumulation that may cause secondary pollution or surface scratches, thus ensuring grinding quality.

Long Service Life
Diamond grains are evenly distributed and firmly bonded, maintaining consistent grinding performance. The pad wears off layer by layer, providing sustained and stable grinding force, reducing usage costs.

Green and Environmentally Friendly
Some diamond thinning pads can use water or lubricants instead of traditional grinding fluids, effectively reducing environmental pollution and machine corrosion.

Edge Conditioning
Prior to use, the diamond pad usually requires edge conditioning to ensure a flat surface and expose the abrasives, achieving optimal grinding performance.

Selection of Suitable Medium
Water or coolant is generally used as the medium to lubricate, carry away debris, and cool the pad, improving grinding efficiency and quality while extending the pad’s service life.

Optimization of Process Parameters
Adjust process parameters such as pressure and rotation speed based on different materials and process requirements to achieve the optimal balance between cutting force and pad wear.
