Abstract:

Embodiments of the disclosure relate to a method of preparing a direct plated substrate. In the method, a dielectric layer is provided that has a first major surface, a second major surface opposite to the first major surface, and a thickness between the first major surface and the second major surface. The thickness of the dielectric layer is no more than 100 .mu.m. A first metal layer is applied to the first major surface of the dielectric layer. A second metal layer is applied to the second major surface of the dielectric layer. A base plate is joined to the second metal layer, and a metal substrate is joined to the first metal layer. A direct plated substrate made according to the method is also described herein.
