Flexible Copper Clad Laminate with Casting and lamination 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.
