Abstract
Abstract An arrangement for mounting a dual-in-line packaged integrated circuit (DIP) to a thick/thin film circuit wherein a portion of each DIP lead is formed into a U-shape including a horizontal foot portion. The arrangement further includes a complementary socket which accepts the U-shaped DIP leads in opposite sides thereof. The socket is then soldered to either a thick/thin film circuit of a circuit board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
An arrangement for mounting and electrically connecting an integrated circuit package having at least two side surfaces and a lower surface, to a planar surface including conductive portions, comprising: at least two electrical leads, each lead including a fixed end, an intermediate section and a free end, each of said fixed ends integrally mounted to a different one of said integrated circuit package side surfaces directly opposite each other and each of said intermediate sections extending vertically and in a spaced relationship to a respective side surface beyond said lower surface to a free end; and each of said free ends U-shaped in cross section including a first leg extending perpendicularly from said intermediate section parallel to said integrated circuit lower surface and a second leg parallel to said first leg; socket means including an insulative body and at least two electrical terminals extending from the interior of said body and electrically connected to said conductive portions, and at least two openings, each of said openings extending through said body to a different one of said terminals and each of said openings formed to accept a different one of said integrated circuit free ends, with each of said free ends engaging a respective terminal, mounting and electrically connecting said integrated circuit thereat.
Claim 2
Dependent Claim
212 words
An arrangement for mounting and electrically connecting an integrated circuit package having at least two side surfaces and a lower surface, to a planar surface including conductive portions, comprising: at least two electrical leads, each lead including a fixed end, an intermediate section and a free end, each of said fixed ends integrally mounted to a different one of said integrated circuit package side surfaces directly opposite each other and each of said intermediate sections extending vertically and in a spaced relationship to a respective side surface beyond said lower surface to a free end; and each of said free ends U-shaped in cross section including a first leg extending perpendicularly from said intermediate section parallel to said integrated circuit lower surface and a second leg parallel to said first leg; socket means including an insulative body and at least two electrical terminals extending from the interior of said body and electrically connected to said conductive portions, and at least two openings, each of said openings extending through said body to a different one of said terminals and each of said openings formed to accept a different one of said integrated circuit free ends, with each of said free ends engaging a respective terminal, mounting and electrically connecting said integrated circuit thereat.
Claim 3
Dependent Claim
89 words
An arrangement for mounting and electrically connecting an integrated circuit package as claimed in claim 1, wherein: said socket means body is rectangular in cross-section including first and second vertical sides and each of said electrical terminals including a fixed end and a free end, each of said free ends extending outwardly from the interior of said body from a surface adjacent said first and second vertical sides and each of said electrical terminal fixed ends mounted adjacent and parallel to a different one of said socket vertical sides.
Claim 4
Dependent Claim
74 words
An arrangement for mounting and electrically connecting an integrated circuit package as claimed in claim 2, wherein: each of said openings is U-shaped in cross-section vertically arranged on a respective one of said vertical sides adjacent a different one of said fixed terminal ends and each of said openings tapers inwardly into said insulative body from a broad open mouth to a closed end formed by a respective one of said fixed terminal ends.
Claim 5
Dependent Claim
36 words
An arrangement for mounting and electrically connecting an integrated circuit package as claimed in claim 3, wherein: said integrated circuit includes a plurality of electrical leads and each of said free ends are U-shaped in cross-section.
Claim 6
Dependent Claim
84 words
An arrangement for mounting and electrically connecting an integrated circuit package as claimed in claim 4, wherein: said socket means body includes a plurality of electrical terminals extending from said body at said surface adjacent said first and second sides and a plurality of openings corresponding to and in juxtaposition with said integrated circuit free ends and each of said body openings adjacent a respective one of said electrical terminals fixed ends accepting a respective one of said integrated circuit leads free ends therein.
Claim 7
Dependent Claim
51 words
An arrangement for mounting and electrically connecting an integrated circuit package as claimed in claim 5, wherein: said planar surface conductive portions comprise a plurality of plated through bores and each electrical terminal free end is disposed to be inserted into a different one of said bores and fixedly mounted thereat.
Claim 8
Dependent Claim
68 words
An arrangement for mounting and electrically connecting an integrated circuit package as claimed in claim 5, wherein: said planar surface conductive portions comprise a plurality of conductive pads and each of said terminal free ends extend outwardly from said socket means and are formed into a horizontal foot portion and each of said foot portions disposed to be fixedly mounted to a different one of said conductive pads.
