Abstract:
A substrate for mounting electronic components thereto, said substrate comprising:a layered base of a ceramic material, said layered base having a plurality of ceramic layers which are joined together in a stack, and a plurality of conducting vias passing through said stack from a top to a bottom of said stack, at least one of said plurality of conducting vias having a top at said top of said stack and a bottom at said bottom of said stack where said top and said bottom of said conducting vias are offset from one another relative to said top and said bottom of said stack;a first conducting layer on a top surface of said layered base;a first dielectric layer of a material different than the ceramic material, said first dielectric layer covering said tope surface and said first conducting layer;a second conducting layer on said first dielectric layer, lines in said second conducting layer being connected to lines in said first conducting layer; andat least one mounting location on a substrate surface suitable for mounting an electronic component and connecting the mounted electronic to said second conducting layer.
