About This Product

By applying "T4X" processing, which has a unique micro-roughening treatment shape, to the raw foil "SV", which features ultra-low roughness and double-sided gloss, a high anchoring effect is achieved despite the ultra-low roughness. It demonstrates high performance in a wide range of fields, from rigid PCBs where transmission characteristics and fine wire processing are important to FPCs where transparency is important.

■Roughening processing imageBy applying the "T4X" process, which has a unique micro-roughening treatment shape, to the raw foil "SV", which features ultra-low roughness and double-sided gloss, it achieves a high anchoring effect despite its low roughness.

■Roughened surface SEMThis is a surface treatment with densely applied roughening particles that are much smaller than conventional spherical roughening.

Features of ultra-fine roughening treatment “T4X”
■Ultra/low roughness rough surfaceSubmicron ultra-fine roughening treatment increases adhesion strength by increasing surface area without affecting roughness.

■High adhesion strengthOur unique micro-roughening treatment exhibits a high anchoring effect, achieving high adhesion strength despite low roughness.

■High base material transparencyDue to the ultra-fine surface topography, flexible substrates can achieve high transparency after etching.

■High circuit visibilityThe black roughening treatment of T4X has a high color contrast with the base material, and the visibility of the back side of the circuit through the film base material is extremely high.

■No powder falling offDespite being ultra-finely processed, it has high adhesion properties, so there is no powder falling and there is no need to worry about line contamination.

■FeaturesWe have a rich lineup of thicknesses ranging from the thinnest 6μm to 35μm. We have achieved the lowest level of roughness among electrolytic copper foils that have undergone roughening treatment.
