The thinning grinding wheel is widely used in the fields of LED chips, integrated circuit silicon wafers, etc. of the electronics industry, and is mainly used for thinning and grinding of semiconductor wafers. 

 

The processed objects include: discrete devices, integrated circuit substrate silicon wafers, sapphire epitaxial wafers, silicon wafers, gallium arsenide, GaN wafers, silicon-based chips, etc. The application process mainly includes: rough grinding processing and finishing processing of back thinning and front grinding. 

Our Company’s thinning grinding wheel specifications:

a). Specifications: diameter 200mm/250mm/265mm/280mm/300mm/380mm, etc.; we can also design and manufacture a variety of single-ring, multi-ring, oblique
tooth thinning grinding wheel according to customer needs. 

b). Particle size: 230/270, 270/325, 400/500, 600/700; 

c). Ending runout: ≤0.04mm 

d). Excircle runout: ≤0.05mm 

e). Dynamic balance criteria: G1

 

The grinding wheel produced by our Company has high processing efficiency, shallow scratch marks, thin grinding damage layer, excellent processing quality, and
long service life, which can reduce the costs of the grinding process by about 30%. At present, our products have replaced the imported products of many
customers. 

Customer actual usage data:
