Method of making electrodeposited copper foil.

摘要

Disclosed is a method of making electrodeposited copper foil which comprises carrying electrolysis by adding a water-soluble cellulose ether to an electrolytic solution. A profile of the matte side nodules of the electrodeposited copper foil obtained by the method of the present invention can be easily controlled, and the electrodeposited copper foil which is high above IPC specification Class 3 in elongation at room temperature and high temperature can be obtained.
