The precision lapping technology to machine the copper substrate using semi-fixed abrasive plate was studied. The surface roughness and material removal rate as the evaluation of indicators, the influences of the different lapping parameters on the surface roughness and material removal rate were discussed and analyzed. Experimental results indicated that the copper substrate could be efficiently machined by semi-fixed abrasive plate of 800(superscript #) SiC abrasive, and the initial roughness Ra of a machined surface could be improved from 0.553μm to 0.28μm in 10min, produced an ideal rarely scratch surface. Then processed copper polished by diamonded grinding paste, it could be satisfied for the Ni-Pd-P alloy thin film growth.
