Abstract: A method of manufacturing a metal-clad laminate and uses of the same are provided. The method comprises the following steps: (a) impregnating a reinforcement material with a first fluoropolymer solution, and drying the impregnated reinforcement material under a first temperature to obtain a first prepreg; (b) impregnating the first prepreg with a second fluoropolymer solution, and drying the impregnated first prepreg under a second temperature to obtain a second prepreg; and (c) laminating the second prepreg and a metal-clad to obtain a metal-clad laminate, wherein the first fluoropolymer solution has a first fluoropolymer, the second fluoropolymer solution has a second fluoropolymer, and the first fluoropolymer and the second fluoropolymer are different.

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.
