Compare 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.
3. Width: rolling copper foil width ≤ 620mm, electrolytic copper foil width ≤ 1380mm
4. Density: rolled copper foil higher density, the surface is relatively smooth, conducive to the production of printed circuit board after the rapid transmission of the signal, so high-frequency high-speed transmission, fine lines printed circuit board also used some calendering copper Foil.
5. Surface treatment width:rolled copper foil be limited by Surface treatment widest effective width of 520mm.
