| titleOfInvention | Metal foil, metal foil with carrier, copper clad laminate and printed wiring board |
| abstract | The invention discloses a metal foil, a metal foil with a carrier, a copper-clad laminate and a printed circuit board. A plurality of protrusions are distributed on one side of the metal foil, and the protrusions have the following microscopic appearance: the protrusions The lower half of the raised part connected to the one side of the metal foil has a restriction part, and the diameter of the circumscribed circle of the cross section of the restriction part is smaller than the skin depth of the metal foil; The surface area of the portion above the restriction portion is larger than the surface area of the rest of the protrusion. The embodiment of the present invention can not only reduce the high frequency signal transmission loss of the metal foil, but also enable the signal transmission line formed by the metal foil and the dielectric layer to have good peel strength. |
