ISO 25um Electrolytic Copper Foil More Than 1 N / Mm Peel Strength

Standard thickness 25mic electrolytic ED copper foil for PCB

Introduction

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.

Features:

1. the treated foil in gray or red

1. High peel strength

3. Good etch ability

4. Excellent adhesion to etching resist

Application:

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.

Package:wooden carton
