Features of high ductility ED copper foil:
1. Good etch ability
2. Excellent adhesion to etching resist
Classify :
The ED copper foils for PCB can be divided into below parts:
(STD-E)- standard electrodeposited copper foil
(HD-E)-high ductility electrodeposited copper foil
(HTE-E)-high temperature elongation electrodeposited copper foil
(LP-E)-low profile electrodeposited copper foil
(VLP-E)-very low profile electrodeposited copper foil
difference between CA copper foil and ED copper foil
1. Process: rolled copper foil (Rolling process),ED copper foil (Electrodeposition process)
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. Surface treatment width:rolled copper foil be limited by Surface treatment widest effective width of 520mm.
Package:wooden box
