Red Low Profile ED Copper Foil 15um 18um 35um Used For Samsung
Phone Heat Sink
Quickly details
Matte side treatment low profile foil in back/red.
Thickness: 15um,18um.35um
Width: 1290mm, 640mm
ID: 76 mm,152 mm
Features:
1. the treated foil in grey 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. Very low profile enables to make fine circuit pattern
Application:
1. Casting and lamination type FCCL
2. Super fine pattern FPC&PWB
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.
