Difference between CA Copper Foil and ED Copper Foilca

Process: rolled copper foil (Rolling process),ED copper foil (Electrodeposition process)
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.
