Product Details
Thickness 12um 18um 35um 50um 70um Very Low Profile Copper Foil for
Mobile Phone Wireless Charging
Sub-micron micro-roughening treatment significantly increases
surface area without affecting roughness, which is especially
helpful for increasing adhesion strength. With high particle
adhesion, there is no worry of particles falling off and
contaminating lines. The Rzjis value after roughening is maintained
at 1.0 µm and transparency of the film after being etched is also
good.

Features
The treated foil is pink or black electrolytic copper foil of very
low surface roughness. Compared with regular electrolytic copper
foil, this VLP foil has finer crystals, which are equiaxed ones
with flat ridges, have a surface roughness of 0.55μm, and have such
merits as better size stability and higher hardness. This product
is applicable to high-frequency and high-speed materials, mainly
flexible circuit boards, high-frequency circuit boards, and
ultra-fine circuit boards.
- Very Low profile
- High MIT
- Excellent etchability
Typical Application
- 2layer 3layer FPC
- EMI
- Fine circuit pattern
- Mobile phone Wireless charging
- High frequency board
