Metal-clad laminate, printed circuit board, and method for manufacturing the same
Abstract:
A metal-clad laminate, a printed circuit board using the same and a method for manufacturing the metal-clad laminate. The metal-clad laminate comprises:



a first dielectric layer, comprising a first dielectric material and not comprising a reinforcing fabric, the first dielectric material comprising 20 wt % to 60 wt % of a first fluoropolymer and 40 wt % to 80 wt % of a first filler;
a second dielectric layer disposed on one side of the first dielectric layer and comprising a reinforcing fabric and a second dielectric material formed on the surface of the reinforcing fabric, wherein the thickness of the reinforcing fabric is not higher than 65 μm and the second dielectric material comprises 55 wt % to 100 wt % of a second fluoropolymer and 0 to 45 wt % of a second filler; and
a metal foil disposed on the other side of the second dielectric layer that is opposite to the first dielectric layer.
