Following an introduction of the production of rolled copper foil worldwide, the production process and key technology of the rolled copper have been analyzed, in which the thickness control, surface quality and surface treatment are the essential processes. The all-round quality management guarantees the production of rolled copper foil. In addition, based on the applications and industrial standards of electronic foil, a comprehensive comparison has been made on various properties between the electrolytic copper foil and rolled copper foil. Comparatively, roiled copper foil has better extensibility and folding resistance, higher softening temperature and strength, lower surface roughness, which is one of the key materials in manufacturing flexible printed circuit board substrate.
