Compare between CA/rolled copper foil and ED/electrolytic copper foil
1. Process: rolled copper foil (Rolling process),ED copper foil
(Electrodeposition process)
2. Strength toughness: rolled copper foil is a flaky crystalline
structure, so the strength and toughness is better than
electrolytic copper foil, so most of the rolling copper foil used
in flexible printed circuit boards.
