Abstract
Abstract In a wired base plate for an electronic part, an infinite number of metallic posts made of copper are provided to a lid joining section of a plural wire layer portion, which section includes a lid joining surface area to which a lid is joined. The metallic posts supports a pressure applied thereto from a lid at the time of mounting of the wired base plate on a circuit board and prevent the plural wire layer portion having a plurality of conductor wire layers and a plurality of resinous insulation layers, from being deformed by compression. A package for an electronic part having such a wired base plate is also provided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
A wired base plate for an electronic part comprising: a substrate; a plural wire layer portion disposed on said substrate and having a plurality of resinous insulation layers and a plurality of conductor wire layers which are disposed by interposing therebetween said resinous insulation layers, respectively; said plural wire layer portion having a lid joining peripheral section including a lid joining surface area to which a lid is joined; and pressure supporting means disposed in said lid joining section for supporting a pressure applied to said lid joining peripheral section by way of the lid; wherein said pressure supporting means includes a plurality of metallic bodies which are formed in said insulation layers, respectively, and which are axially aligned with each other to constitute an axially straight, integral post which penetrates said plural wire layer portion throughout the thickness thereof.
Claim 2
Dependent Claim
140 words
