Classify:
The ED copper foils for PCB can be divided into below parts:
(STD-E)- (HD-E)- (HTE-E)- (LP-E)- (VLP-E).
Use for :
CCL,Polyimide board,Epoxy board,PCB and antenna PCB.
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
Package:wooden carton
