Abstract
Abstract An interconnect system is provided in which one or more laminated modules embodying electrical devices can be stacked in a three dimensional configuration upon a printed circuit board. One or more electrical devices is surface mounted to a recessed area at the upper surface of each laminated module, and each laminated module includes male pins and female sockets. The male pins can be releasibly engaged within sockets upon a printed circuit board. Additionally, the male pins of one laminated module can be engaged within female sockets of another laminated module in building-block fashion. Conductive paths are formed entirely through the laminated module between respective sockets and pins. The conductive paths are arranged in a less dense fashion than bond locations adjacent each electrical device. The bond locations are therefore offset from conductive paths to provide fan-out and redistribution features.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
250 words
A laminated module comprising: an intermediate component having first and second opposite sides, said intermediate component having a plurality of spaced first vias extending through said intermediate component and terminating at the first and second opposite sides at a position offset from a plurality of intermediate component bonding pads electrically connected therewith; a female component having third and fourth opposite sides, said female component having a plurality of spaced second vias extending through said female component and terminating at the third side as sockets and the fourth side as female component bonding pads in registry with the plurality of intermediate component bonding pads upon the intermediate component first side; a male component having fifth and sixth opposite sides, said male component having a plurality of spaced third vias extending through said male component and terminating at the sixth side as pins and the fifth side as male component bonding pads in registry with the plurality of intermediate component bonding pads upon the intermediate component second side; an area upon the first side of said intermediate component adapted for receiving an integrated circuit having electrical wires extending from said integrated circuit to said intermediate component bonding pads; and wherein said intermediate component bonding pads, said female component bonding pads and said male component bonding pads each include a solder coating that, when one solder coated bonding pad is placed in registry and engaged with another solder coated bonding pad and thereafter heated, allows said bonding pads permanent fixture to one another.
Claim 2
Dependent Claim
250 words
A laminated module comprising: an intermediate component having first and second opposite sides, said intermediate component having a plurality of spaced first vias extending through said intermediate component and terminating at the first and second opposite sides at a position offset from a plurality of intermediate component bonding pads electrically connected therewith; a female component having third and fourth opposite sides, said female component having a plurality of spaced second vias extending through said female component and terminating at the third side as sockets and the fourth side as female component bonding pads in registry with the plurality of intermediate component bonding pads upon the intermediate component first side; a male component having fifth and sixth opposite sides, said male component having a plurality of spaced third vias extending through said male component and terminating at the sixth side as pins and the fifth side as male component bonding pads in registry with the plurality of intermediate component bonding pads upon the intermediate component second side; an area upon the first side of said intermediate component adapted for receiving an integrated circuit having electrical wires extending from said integrated circuit to said intermediate component bonding pads; and wherein said intermediate component bonding pads, said female component bonding pads and said male component bonding pads each include a solder coating that, when one solder coated bonding pad is placed in registry and engaged with another solder coated bonding pad and thereafter heated, allows said bonding pads permanent fixture to one another.
Claim 3
Dependent Claim
40 words
The laminated module as recited in claim 1, wherein said intermediate component comprises a plurality of dielectric layers interlaced between a plurality of conductive layers, said dielectric and conductive layers extending generally parallel to said first and second opposite sides.
Claim 4
Dependent Claim
33 words
The laminated module as recited in claim 2, wherein at least one said conductive layer comprises coplanar, spaced conductive traces extending between, and in electrical contact with, at least two said first vias.
Claim 5
Dependent Claim
20 words
The laminated module as recited in claim 1, wherein said first vias are drill holes plated with a conductive metal.
Claim 6
Dependent Claim
36 words
The laminated module as recited in claim 1, wherein said intermediate component bonding pads, said female component bonding pads, said male component bonding pads, and said first, second and third vias are each of circular cross-section.
Claim 7
Dependent Claim
43 words
The laminated module as recited in claim 1, wherein said intermediate component bonding pads, said female component bonding pads and said male component bonding pads are each of equal cross-section diameter dissimilar than the cross-section diameter of said first, second and third vias.
Claim 8
Dependent Claim
38 words
The laminated module as recited in claim 1, wherein the solder coated bonding pads, when heated, provides permanent connection of said intermediate component, said female component and said male component with one another to form a unibody structure.
Claim 9
Dependent Claim
46 words
The laminated module as recited in claim 7, wherein said unibody structure comprises opposite sides with said pins on one side and said sockets on the opposite side, said pins and sockets are dimensioned to frictionally mate with another unibody structure formed according to claim 8.
