FCCL ED Copper Foil
Quickly details
Thickness: 0.012-0.070 mm
Width: 5-520 mm
Length: 500-5000 M
ID: 76 mm,152 mm
Alloy: T2,C11000,C1100,C101,E-Cu58
Temperature: High
Features:
1. the treated foil in gray or red
2. High profile with properties of LP-S-B/R suitable for FCCL
3. Grain structure of copper foil leads to high flexibility
4. Excellent etching performance
5. low profile enables to make fine circuit pattern
Application:
1. Casting and lamination type FCCL
2. Super fine pattern FPC
3. Chip on flex (COF) for LED
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.
