Abstract
Abstract An electronic module having two insulating substrates which are provided with printed wiring and which are connected to circuit elements, and mounted against opposite sides of a heat-dissipating body. The sides of the substrates are remote from the sides supporting the printed wiring and/or thin-layer circuit elements are glued to the heat-dissipating body which is between the substrates, and the required connection leads are enveloped by an insulating envelope.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
An electronic module comprising: first and second insulating substrates each having a first side and surface wiring on a second side, a first heat-dissipating body attached to said first side of the first substrate, a second heat-dissipating body attached to said first side of the second substrate, means for making external electrical connections to the surface wiring of at least one of said substrates, at least two connection leads electrically connecting wiring on the first substrate to a wiring on the second substrate, means for permanently mechanically connecting said first and second heat-dissipating bodies together in abutting relationship, a first portion of each of said bodies being disposed between the two substrates and a second portion of each of said bodies extending beyond said substrates, and insulating material enveloping said substrates, said means for making external electrical connections, and said first portions.
Claim 2
Dependent Claim
142 words
An electronic module comprising: first and second insulating substrates each having a first side and surface wiring on a second side, a first heat-dissipating body attached to said first side of the first substrate, a second heat-dissipating body attached to said first side of the second substrate, means for making external electrical connections to the surface wiring of at least one of said substrates, at least two connection leads electrically connecting wiring on the first substrate to a wiring on the second substrate, means for permanently mechanically connecting said first and second heat-dissipating bodies together in abutting relationship, a first portion of each of said bodies being disposed between the two substrates and a second portion of each of said bodies extending beyond said substrates, and insulating material enveloping said substrates, said means for making external electrical connections, and said first portions.
Claim 3
Dependent Claim
55 words
A module as claimed in claim 1 wherein said heat-dissipating bodies each have at least one recess, said recesses being aligned to form a common recess, and said module includes at least one circuit element connected to one of the substrates on the second side of the substrate, said common recess accomodating said circuit element.
Claim 4
Dependent Claim
25 words
A module as claimed in claim 1, wherein said connection leads are exposed for making permanent electrical connection through an opening in said insulating material.
Claim 5
Dependent Claim
27 words
A module as claimed in claim 1 wherein said means for making external electrical connections comprise a plurality of connection leads connected to said first substrate only.
Claim 6
Dependent Claim
214 words
An electric module comprising: first and second insulating substrates each having a first side and surface wiring on a second side, a first heat-dissipating body having at least one recess, attached to said first side of the first substrate, a second heat-dissipating body having at least one recess, attached to said first side of the second substrate, means for making external electrical connections to the wire surface wiring of at least one of said substrates, at least two connection leads electrically connecting wiring on the first substrate to a location on the second substrate, means permanently mechanically connecting said first and second heat-dissipating bodies together in abutting relationship, a first portion of each of said bodies being disposed between the two substrates and a second portion of each of said bodies extending beyond said substrates, said recesses being within respective first portions and aligned to form a common recess, at least one circuit element connected to one of the substrates on the second side of the substrate, and accommodated in said common recess, and insulating material enveloping said substrates, said means for making external electrical connections, and said first portions, an opening extending through said enveloping material and at least one of said bodies to said common recess to permit adjustment of said element.
