Abstract
Abstract An electrical connection pin blank having at least one compliant section is affixed to a first circuit board by compressive deformation in such a way that the compliant section of the pin blank projects outwardly from the surface of the first circuit board. The end of the pin projecting from the first circuit board is then inserted into a corresponding opening in a second circuit board and the two boards brought together until the second circuit board is firmly affixed to the complaint section of the pin by compliant pin connection.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
A module comprising (1) a substrate defining a first surface, a second surface spaced from said first surface and at least one hole communicating between said first and second surfaces for receiving an electrical connection pin, and (2) an electrical connection pin having a substrate-engaging section received in said hole, said substrate-engaging section defining a first bulge engaging said first surface and a second bulge engaging said second surface, said first bulge being formed by compressive deformation while said pin is in said hole so that said first and second bulges securely fasten said pin to said substrate, said pin further defining a first compliant section spaced from said substrate-engaging section and projecting from said first bulge for affixing said pin to a carrier by compliant pin connection, said first compliant section defining at least one protrusion extending outwardly from the central axis of said pin by a distance greater than the radius of the pin in the remainder of the pin body.
Claim 2
Dependent Claim
163 words
A module comprising (1) a substrate defining a first surface, a second surface spaced from said first surface and at least one hole communicating between said first and second surfaces for receiving an electrical connection pin, and (2) an electrical connection pin having a substrate-engaging section received in said hole, said substrate-engaging section defining a first bulge engaging said first surface and a second bulge engaging said second surface, said first bulge being formed by compressive deformation while said pin is in said hole so that said first and second bulges securely fasten said pin to said substrate, said pin further defining a first compliant section spaced from said substrate-engaging section and projecting from said first bulge for affixing said pin to a carrier by compliant pin connection, said first compliant section defining at least one protrusion extending outwardly from the central axis of said pin by a distance greater than the radius of the pin in the remainder of the pin body.
