SUBSTRATE FOR ELECTRICAL CIRCUITS AND METHOD FOR PRODUCING A SUBSTRATE OF THIS TYPE

摘要

The invention relates to a substrate (1) for electrical circuits comprising at least one first composite layer (2) which is produced by means of roll cladding and, after said roll cladding, has at least one copper layer (3) and an aluminium layer (4) attached thereon, wherein at least the surface side of the aluminium layer (4) facing away from the copper layer (3) is anodized for the generation of an anodic or insulating layer (5) made of aluminium oxide, and wherein the anodic or insulating layer (5) made of aluminium oxide is connected to a metal layer (7) or at least one second composite layer (2′) or at least one paper-ceramic layer (11) via at least one adhesive layer (6, 6′).
