Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A printed circuit board comprising one or more insulating layers having a top outer surface and a parallel bottom outer surface, a pin-receiving conductive element that extends along a first axis generally perpendicular to said top and bottom outer surfaces and extends from one said outer surface toward the other, said element having a pin receiving portion at said one surface of a first size, said pin receiving portion extending partially along said first axis, said element having a second portion extending further along said first axis, said second portion being a size smaller than said first size, and one or more second conductive elements that are parallel to said outer surfaces and are generally perpendicular to said first axis and located in a plane intersecting said first axis at said second portion.
Claim 2
Dependent Claim
133 words
A printed circuit board comprising one or more insulating layers having a top outer surface and a parallel bottom outer surface, a pin-receiving conductive element that extends along a first axis generally perpendicular to said top and bottom outer surfaces and extends from one said outer surface toward the other, said element having a pin receiving portion at said one surface of a first size, said pin receiving portion extending partially along said first axis, said element having a second portion extending further along said first axis, said second portion being a size smaller than said first size, and one or more second conductive elements that are parallel to said outer surfaces and are generally perpendicular to said first axis and located in a plane intersecting said first axis at said second portion.
Claim 3
Dependent Claim
37 words
The board of claim 1 wherein one said insulating layer is a cap and another said insulating layer is a sub-board, said pin receiving portion being in said cap, and said second portion being in said sub-board.
Claim 4
Dependent Claim
23 words
The board of claim 2 further comprising a plurality of said pin receiving conductive elements and a plurality of said second conductive elements.
Claim 5
Dependent Claim
29 words
The board of claim 3 wherein each said pin receiving conductive element is a conductive layer over a counterbore in said cap and a connected through-hole in said sub-board.
Claim 6
Dependent Claim
16 words
The board of claim 4 wherein said layer comprises sublayers of electrolytic copper and electroless copper.
