RoHS ED Electrolytic Thin Copper Foil 1 / 2 Oz Thickness High Coarse

ED Electrolytic Thin Copper Foil Description:

ED (Electro-Deposited) electrolytic thin copper foil refers to a type of copper foil that is produced through an electroplating 

process. It is commonly used in various industries, including electronics, printed circuit board (PCB) manufacturing, and 

lithium-ion battery production.

Compare between CA copper foil and ED copper foil

1. Width: rolling copper foil width ≤ 620mm, electrolytic copper foil width ≤ 1380mm

2. 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.

3. 3. Surface treatment width:rolled copper foil be limited by Surface treatment widest effective width of 520mm.

ED Electrolytic Thin Copper Foil Specifications:

• Thickness: 12micron-70micron

• Width: 5-520 mm

• Length: 500-5000 M

• Coil ID: 76 mm,152 mm

• Purity:99.8%

ED Electrolytic Thin Copper Foil Features:

1. The treated foil in red

2. High peel strength

3. Anti foil cracking by high elongation at elevated temperature.

4. Eco-friendly products and processes

5. Good etch ability

6. Excellent adhesion to etching resist
