black 18 um very low profile electrodeposited copper foil for CCL
Back and red color.
Thickness: 1/2 OZ,Width: 5-1380 mm.
Cu Content: 99.8%.
- Excellent etching performance.
- Very Low profile enables to make fine circuit pattern.
- High elongation.
VLP ED copper foils use:
- Super fine pattern PWB.
- Chip on flex (COF) for LED.
Difference between rolled copper foil and electrolytic copper foil.
# Process is difference: rolled copper foil (Rolling process),ED copper foil (Electrodeposition process).
# Performance is different ,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.
