about JIMAGROUP.
JIMA GROUP generated from metal products processing , has been growing rapidly in aluminum and copper precision processing,and now its business has expanded to lithium battery etc new energy resources and flexible packaging .For example,hard alloy aluminum sheet.copper foil,pet can,aluminum can, beer can,lithium battery.We hold firm on the creeds that"optimize the industrial chain,expand the deeply processing and explore the products extensively." we consistently pursue to develop adding value products and blue ocean products .Our goal is to be stronger,to be global.
Superior precision processing products:
PCB copper foil
Quickly details
single side side treatment low profile foil in back/red.

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.
Typical properties of High temperature elongation copper foil(for epoxy &polyimide board).
