How much do you know about the role and influencing factors of polishing pads? Follow the editor of quality wool polish pad price for a simple understanding!
1. Function
1. Transport the polishing liquid to different areas of the polishing pad effectively and evenly;
2. The chemical reaction is fully carried out after polishing; the reactants and debris are discharged smoothly to achieve the removal effect;
3. Maintain the polishing liquid film on the surface of the polishing pad so that the chemical reaction can proceed fully;
4. Keep the polishing process stable and the surface is not deformed, in order to obtain a better surface morphology of the wafer;

2. Influencing factors
1. Hardness: The hardness of the polishing pad determines the ability to maintain the accuracy of the surface shape;
2. Compression ratio: The compression ratio reflects the anti-deformation ability of the polishing pad;
3. Conservation capacity: the conservation capacity of the polishing pad is the quality of the polishing liquid stored in the polishing pad per unit volume;
4. Roughness: Surface roughness is the degree of unevenness on the surface of the polishing pad;
5. Density: Density is the degree of compactness of the polishing pad material;
The above is the editor of quality wool polish pad price: a brief introduction to the role and influencing factors of the polishing pad.
