What is the function of the polishing pad in the work of the flat grinding machine?
The polishing fluid is effectively and uniformly transported to different areas of the polishing pad;After polishing, the chemical reaction is fully carried out; the reactants and chips are discharged smoothly to achieve the removal effect;
The polishing liquid film on the surface of the polishing pad is maintained so that the chemical reaction is fully carried out;
The polishing process is stable and the surface is not deformed so as to obtain better surface topography of the wafer.
