Product Details
Matte Side Treatment Very Low-Profile Copper in Black/Red
(VLP-S-B/R)
The raw foil, which has a glossy surface with ultra low roughness
on both sides, is treated with JIMA's proprietary micro-roughening
process to achieve high anchoring performance and also ultra low
roughness. It offers high performance in a wide range of fields,
from rigid printed circuit boards that prioritize transmission
properties and fabrication of fine pattern to flexible printed
circuits that prioritize transparency.
