Abstract

Abstract An electronic assembly combines a number of commensurate printed circuit boards bonded to a common, flexible, interconnecting substrate in an alternately folded and layered arrangement against an end board that has a comb of terminals for mounting into a motherboard connector. The flexible substrate is sandwiched between half-sections of each board, allowing mounting of components from both faces of the board. The assembly is particularly indicated for high density applications such as memory modules.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 207 words
An electronic assembly which comprises: a flexible, insulating substrate having a network of conductive leads and connecting stations applied thereto; at least two substantially quadrangular circuit boards; each of said boards laminarly split into substantially symmetric half-sections; each of said half-sections having pads on a first face for mounting electronic components; each of said half-sections having an opposite second face bonded to said substrate; said half-sections laminated together on either side of a portion of the substrate sandwiched therebetween; said boards bonded in a side-by-side, parallely spaced-apart configuration; a first of said boards having a comb of connecting terminals integral with said first board along a first edge; said comb sized and dimensioned to engage a connecting port on a supporting structure; a plurality of feed-through connections on each of said boards interconnecting a plurality of said pads and terminals with said connecting stations; wherein any gap between two parallely spaced-apart edges of any two adjacent boards is wide enough to allow mounting of said boards in a parallel, face-to-face, layered arrangement by folding said substrate at said gap; said gap being wide enough to allow for an air space between any opposite facing components attached to separate boards; and, said gap having no components attached thereto.
Claim 2
Dependent Claim 207 words
An electronic assembly which comprises: a flexible, insulating substrate having a network of conductive leads and connecting stations applied thereto; at least two substantially quadrangular circuit boards; each of said boards laminarly split into substantially symmetric half-sections; each of said half-sections having pads on a first face for mounting electronic components; each of said half-sections having an opposite second face bonded to said substrate; said half-sections laminated together on either side of a portion of the substrate sandwiched therebetween; said boards bonded in a side-by-side, parallely spaced-apart configuration; a first of said boards having a comb of connecting terminals integral with said first board along a first edge; said comb sized and dimensioned to engage a connecting port on a supporting structure; a plurality of feed-through connections on each of said boards interconnecting a plurality of said pads and terminals with said connecting stations; wherein any gap between two parallely spaced-apart edges of any two adjacent boards is wide enough to allow mounting of said boards in a parallel, face-to-face, layered arrangement by folding said substrate at said gap; said gap being wide enough to allow for an air space between any opposite facing components attached to separate boards; and, said gap having no components attached thereto.
Claim 3
Dependent Claim 49 words
The assembly of claim 1, wherein a second an da third of said boards are successively and alternately folded in a parallel and layered arrangement with respect to the first board, thereby allowing said network of conductive leads to lie in same electronic plane facilitating memory module access design.
Claim 4
Dependent Claim 18 words
The assembly of claim 1, which comprises means for holding said boards in said parallel and layered arrangement.
Claim 5
Dependent Claim 39 words
The assembly of claim 3, wherein said means for holding comprise: each of said boards having at least one feed-through; said feed-throughs sized, dimensioned and positioned in alignment to accommodate passage of at least one post through said feed-throughs.
Claim 6
Dependent Claim 31 words
A plurality of the assembly of claim 1 in combination with a row of parallel, spaced-part connectors mounted on a supporting structure shaped and dimensioned to engage said comb of terminals.
Claim 7
Dependent Claim 21 words
The assembly of claim 1 wherein said comb is the only electronic connection point between said assembly and said supporting structure.
Claim 8
Dependent Claim 21 words
The assembly of claim 6 wherein said comb is the only mechanical connection point between said assembly and said supporting structure.
Claim 9
Dependent Claim 19 words
The assembly of claim 1 wherein said connecting port comprises a Single IN line Memory Module (SIMM) style port.
Claim 10
Dependent Claim 20 words
The assembly of claim 1 wherein said pads are sized, dimensioned and positioned to electronically engage memory integrated circuit modules.
Claim 11
Dependent Claim 14 words
The assembly of claim 2 wherein said arrangement is less than 1.25 centimeters thick.
Claim 12
Dependent Claim 25 words
The assembly of claim 1 which further comprises: means for cooling said assembly which comprise a plurality of holes through said substrate at said gap.
