type,Super fine pattern FPC,Chip on flex (COF) for LED,multilayer
circuit boards.
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.
