Remark: we can accept customization as per your request, Standard
Width,620(±1)mm
Compare between CA copper foil and ED copper foil
. Width: rolling copper foil width ≤ 620mm, electrolytic copper
foil width ≤ 1380mm
. 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.
Details Package: wooden box
Keep the dry environment,and is better use it in 30days.
