Quickly Introduction

Mill Test Certificate of rolled copper foil

Remark: we can accept customization as per your request, Standard Width,620(±1)mm

Compare between rolled 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.
