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.
