Different between CA copper foil and ED 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.
