Abstract
Abstract A connector post or pin is disclosed which is particularly suitable for use with printed circuit board assemblies. The post includes a coined portion which is designed to permit the pin to be easily inserted into holes of a predetermined size in printed circuit boards, and to increase the quality of a solder joint between the post and the printed circuit board. A solder stripe is placed on each post in the coined region to facilitate soldering of the posts to conductive portions of the printed circuit board. The posts are attached in groups to break-away carrier strips to aid in the rapid assembly of large numbers of posts to printed circuit boards. The posts may also include provisions for coupling them to multilayered printed circuit assemblies. A method of fabricating the coined post is also disclosed which converts a post with normally an interference fit in a printed circuit board aperture to a post which is freely received in the aperture together with masses of solder adhered to said post.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
110 words
An electrically conductive post intended for mounting in a plated-through aperture of a printed circuit board, comprising: an elongated body of conductive material having a first body portion and a second body portion, a selected length of said second body portion having a plurality of external surfaces defining a first polyhedral cross-section, a selected length of said second body portion having external surfaces defining a second polyhedral cross-section of smaller area than the area of said first polyhedral cross-section, said external surfaces of saId second selected length being offset from the external surfaces of said first selected length, and solder adhered to the external surfaces of said second selected length.
Claim 2
Dependent Claim
110 words
An electrically conductive post intended for mounting in a plated-through aperture of a printed circuit board, comprising: an elongated body of conductive material having a first body portion and a second body portion, a selected length of said second body portion having a plurality of external surfaces defining a first polyhedral cross-section, a selected length of said second body portion having external surfaces defining a second polyhedral cross-section of smaller area than the area of said first polyhedral cross-section, said external surfaces of saId second selected length being offset from the external surfaces of said first selected length, and solder adhered to the external surfaces of said second selected length.
Claim 3
Dependent Claim
87 words
An electrically conducting post intended for mounting in a plated-through hole of a printed circuit board, comprising: an elongated board of electrically conductive material having a first resilient end portion serving as an electrical contact, a second end portion having elongated surfaces intersecting in sharp corner edges, selected portions of said sharp corner edges being recessed with respect to said intersecting elongated surfaces and substantially blunted to define a third portion of said body, and solder adhered to the periphery of said third portion of said body.
Claim 4
Dependent Claim
87 words
An electrically conducting post intended for mounting in a plated-through hole of a printed circuit board, comprising: an elongated board of electrically conductive material having a first resilient end portion serving as an electrical contact, a second end portion having elongated surfaces intersecting in sharp corner edges, selected portions of said sharp corner edges being recessed with respect to said intersecting elongated surfaces and substantially blunted to define a third portion of said body, and solder adhered to the periphery of said third portion of said body.
Claim 5
Dependent Claim
50 words
The structure as recited in claim 2, wherein said third portion of said body is of polyhedral cross-section, the area of said polyhedral cross-section being smaller than the cross-sectional area of said second end portion, said solder being adhered to the external surfaces of said third portion of said body.
Claim 6
Dependent Claim
30 words
The structure as recited in claim 3, wherein the external surfaces of said third portion of said body are offset with respect to the surfaces of said second body portion.
Claim 7
Dependent Claim
23 words
The structure as recited in claim 2, wherein said first end of said elongated body is removably attached to an integral carrier strip.
Claim 8
Dependent Claim
19 words
The structure as recited in claim 1, wherein said elongated body is removably attached to an integral carrier strip.
