Difference between rolled copper foil and electrolytic copper foil.
Performance is different ,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.Width different:: rolling copper foil width ≤ 620mm, electrolytic copper foil width ≤ 1380mm.
