Fr4 Single Pcb Suppliers and Fr4 Single Pcb Factory,Copper thickness:0.5-6OZ, 24hours for sample,For extra thin PCB, we can make it at 0.15-4.0mm,with or without the soldermask, and copper thickness 1/2OZ, 1OZ. Extra thin FR4 PCB can be bendable similar like a flexible circuit,but more rigid,and cost will be lower,comparing with the same copper traces.

1 Layer Black Soldermask Immersion Gold High TG PCB Board In Panel Format,FR-4 material is a fire code rating, represents a material specification is meant a resin material through the combustion state must be self-extinguishing, it is not a material name, but a material grade. So now FR-4 grade material is typically used in circuit boards, there are many species, but most are based on the so-called four-function (Tera-Function) plus epoxy filler (Filler) and glass fiber made composite materials.
