ABSTRACT:
To reduce warping of a copper clad laminate coated with copper foils of different thicknesses on both sides, and thereby to improve production efficiency of the printed-wiring boards, there is provided a copper clad laminate coated with copper foils of different thicknesses on both sides, wherein a first copper foil on one side of the laminate is not recrystallizable by hot pressing for production of said laminate and a second foil on the other side is recrystallizable by the hot pressing and thicker than the first foil.
