摘要
The small surface roughness of the matte side is the first requirement of the electrodeposited copper foil for the fine pattern. In order to meet the requirement, mass production of the raw foil, which has an unprecedented extremely flat matte side in the electrodeposited copper foil, was realized. Also, adhesion to resin is required of the copper foil for the printed circuit board as its other feature, thus matte side treatment and surface treatment were also reviewed.
