Abstract
Abstract An electrical subassembly structure of two substrates has metalized portions located adjacent to the upper and lower edges on the back of each substrate. Clip on leads are attached to one substrate with a portion of each lead soldered to the lower edge metalized portion. The two substrates are electrically and mechanically joined by soldering upper edge metalized portions together and soldering the lower edge metalized portions of the other substrate to the lead portions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
191 words
An electrical subassembly structure comprising: a first subassembly having a backside and a front side, a second subassembly having a backside and a front side, each of said subassemblies having an upper edge with a plurality of metallized portions located adjacent to said upper edge on its back side and a lower edge with a plurality of metallized portions located adjacent to said lower edge on its back side, a plurality of clip-on leads connected to the lower edge of said first subassembly, each lead having a portion positioned against lower-edge back side metallized portions for providing both electrical and mechanical connections to said first subassembly, the second subassembly being mounted to the first subassembly with at least some of its upper edge back side metalized portions soldered directly to said first subassemble upper-edge back side metallized portions for providing electrical and mechanical inter-connection and at least some of its lower-edge back side metallized portions soldered to said clip-on lead portions for providing electrically and mechanically connection to first subassembly lower-edge back side metallized portions through said clip-on lead portions, whereby the first and second subassemblies form an inverted "v" configuration.
Claim 2
Dependent Claim

An electrical subassembly structure comprising: a first subassembly having a backside and a front side, a second subassembly having a backside and a front side, each of said subassemblies having an upper edge with a plurality of metallized portions located adjacent to said upper edge on its back side and a lower edge with a plurality of metallized portions located adjacent to said lower edge on its back side, a plurality of clip-on leads connected to the lower edge of said first subassembly, each lead having a portion positioned against lower-edge back side metallized portions for providing both electrical and mechanical connections to said first subassembly, the second subassembly being mounted to the first subassembly with at least some of its upper edge back side metalized portions soldered directly to said first subassemble upper-edge back side metallized portions for providing electrical and mechanical inter-connection and at least some of its lower-edge back side metallized portions soldered to said clip-on lead portions for providing electrically and mechanically connection to first subassembly lower-edge back side metallized portions through said clip-on lead portions, whereby the first and second subassemblies form an inverted "v" configuration.
Claim 3
Dependent Claim
22 words
An electrical subassembly as defined in claim 1, in which: the upper edges of the first and second subassemblies are substantially aligned.
Claim 4
Dependent Claim
31 words
An electrical subassembly as defined in claim 3, in which: the lower-edge of the second subassembly extends below the lower edge of the first subassembly for providing additional subassembly surface area.
