Compare between CA copper foil and ED copper foil
1. Width: rolling copper foil width ≤ 620mm, electrolytic copper foil width ≤ 1380mm
2. 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.
3. Surface treatment width:rolled copper foil be limited by Surface treatment widest effective width of 520mm.
