Standard thickness 25mic electrolytic ED copper foil for PCB
The roll shape (from 1/3oz to 2oz thickness)width. In usual, it is from 500mm to 1295mm, the max width could reach to 1370mm.
The normal sheet size is 1295mm*1295mm, 1295mm*1092mm, 1295mm*990mm. it also can be cut to the size as customer’s requirement.
1/3oz, 1/2oz, 1oz, 3oz, 12oz, 14oz are popular thickness, and we can also provide surface treatment service.
1. the treated foil in gray or red
1. High peel strength
3. Good etch ability
4. Excellent adhesion to etching resist
1. Phenolic resin board
2. Epoxy board
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.
