ED Copper Foil with Width 35um, 70um for PCB laminate
Quickly details
1>Thickness: 12um ~140um
2>standard Width: 1290mm
3>ID: 76 mm,152 mm
4>Sample:free provide A4 smaple as per thickness
Application:
1. PCB laminate
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.
