- Title
Effects of process conditions on properties of electrolytic copper foil.

- Abstract
The effects of several process conditions easily controlled during the production of electrolytic copper foil i.e. temperature, flow rate, roughness and polishing method of titanium plate, as well as temperature and laying way in posttreatment on the surface morphology, roughness, tensile strength, total breaking elongation, and gloss of electrolytic copper foil were studied. Controlling the temperature and flow rate of electrolyte within an appropriate range, providing the cathodic titanium roller a roughness (Rz) 2 μm below, and polishing the cathodic titanium roller as straightly as possible are all beneficial for preparation of favorable copper foils. Post-heating where the rough side is towards the ground helps to accelerate the release of residual stress inside the copper foil, reducing the risk of warpage.
