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.

Abstract: A metal-clad laminate is provided. The metal-clad laminate includes:



a dielectric layer, which has a first reinforcing material and a dielectric material formed on the surface of the first reinforcing material, wherein the dielectric material includes 60 wt % to 80 wt % of a first fluoropolymer and 20 wt % to 40 wt % of a first filler;
an adhesive layer, which is disposed on at least one side of the dielectric layer and includes an adhesive material, wherein the adhesive material has 60 wt % to 70 wt % of a second fluoropolymer and 30 wt % to 40 wt % of a second filler; and
a metal foil, which is disposed on the other side of the adhesive layer that is opposite to the dielectric layer,
wherein the melting point of the second fluoropolymer is lower than the melting point of the first fluoropolymer.

Abstract: A fluororesin composition is provided. The fluororesin composition comprises the following constituents:



(A) a first fluororesin, which is polytetrafluoroethylene (PTFE) resin;
(B) a first filler, which is a flat glass fiber; and
(C) particles of a second fluororesin, which are coated with polysiloxane,

wherein, the particle size of the polysiloxane-coated particles of second fluororesin ranges from 0.2 μm to 80 μm, and the melting point of the second fluororesin is lower than the melting point of the first fluororesin.
