Difference between rolled copper foil and electrolytic copper foil.

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.

Surface treatment width:rolled copper foil be limited by Surface treatment widest effective width of 520mm.

ED copper foil standard width is 1295mm,max width is 1380mm
