A single-factor experiment was conducted to explore the influence of rotation speed and lateral swing speed of polishing brush,and polishing current on the performance of copper foil and pinholes.Based on that,the polishing process was also optimized by applying response surface methodology,and thus the performance and apparent quality of copper foil was also improved.The results show that by using on-line polishing,with the rotation speed of the polishing brush at 450 r/min,the lateral swing speed of 350 r/min,and the polishing current of 0.50 A,the smooth surface(S surface)of the generated copper foil is uniform,and the pinhole defects are significantly reduced.
