Abstract

Abstract A printed circuit board assembly usable in a transceiver microphone is disclosed. The assembly comprises a first printed circuit board having components mounted thereon which is fixed to one side of a circuit board carrier by retaining tangs. Second and third printed circuit boards also having components thereon are mounted on an opposite side of the circuit board carrier also by retaining tangs. The first circuit board is connected to the second and third circuit boards via pluralities of bare jumper wires extending between end portions of the first circuit board and adjacent end portions of the second and third circuit boards. The carrier is substantially planar and has integral end projections which form associated notches for receiving each of the jumper wires.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 217 words
A circuit board assembly comprising: at least first and second substantially planar circuit boards having conductive metallizations thereon, each of each circuit boards having a top surface and a bottom surface, some non-planar electrical components mounted on the top surface of each circuit board; an electrically insulated circuit board carrier having raised peripheral shoulders substantially surrounding an effective planar central portion of said carrier, said first and second circuit boards mounted substantially back to back on said raised peripheral shoulders such that said bottom surfaces of said circuit boards are spaced apart from and face each other; said first and second circuit boards electrically interconnected by a plurality of jumper wire elements extending therebetween and soldered to adjacent end portions of each of said first and second circuit boards, and wherein said circuit board carrier has a guide portion formed therein at an end of said carrier adjacent to said adjacent end portions of said first and second circuit boards, said guide portion comprising a plurality of individual spaced projections extending from said adjacent end of said circuit board carrier, said projections forming notches therebetween with each of said jumper wire elements positioned in an associated one of said notches and therefore being spaced apart by said projections, whereby a compact, inexpensive circuit board assembly is provided.
Claim 2
Dependent Claim 217 words
A circuit board assembly comprising: at least first and second substantially planar circuit boards having conductive metallizations thereon, each of each circuit boards having a top surface and a bottom surface, some non-planar electrical components mounted on the top surface of each circuit board; an electrically insulated circuit board carrier having raised peripheral shoulders substantially surrounding an effective planar central portion of said carrier, said first and second circuit boards mounted substantially back to back on said raised peripheral shoulders such that said bottom surfaces of said circuit boards are spaced apart from and face each other; said first and second circuit boards electrically interconnected by a plurality of jumper wire elements extending therebetween and soldered to adjacent end portions of each of said first and second circuit boards, and wherein said circuit board carrier has a guide portion formed therein at an end of said carrier adjacent to said adjacent end portions of said first and second circuit boards, said guide portion comprising a plurality of individual spaced projections extending from said adjacent end of said circuit board carrier, said projections forming notches therebetween with each of said jumper wire elements positioned in an associated one of said notches and therefore being spaced apart by said projections, whereby a compact, inexpensive circuit board assembly is provided.
Claim 3
Dependent Claim 49 words
A circuit board assembly according to claim 1 wherein said carrier includes a plurality of retaining tangs projecting outward from said raised peripheral shoulders of said carrier, some of said retaining tangs contacting each of said first and second circuit boards and thereby affixing said boards to said carrier.
Claim 4
Dependent Claim 45 words
A circuit board assembly according to claim 2 wherein said retaining tangs are positioned within peripheral notches in said first and second circuit boards to thereby minimize the lateral dimensions of said circuit board assembly and aid in positioning said circuit boards on said carrier.
Claim 5
Dependent Claim 23 words
A circuit board assembly according to claim 2 wherein said retaining tangs and guide portion are integrally formed with said circuit board carrier.
Claim 6
Dependent Claim 19 words
A circuit board assembly according to claim 4 wherein said integral circuit board carrier is formed from molded plastic.
Claim 7
Dependent Claim 92 words
A circuit board assembly according to claim 1 which includes a third circuit board mounted substantially coplanar with said second circuit board on said circuit board carrier, said third circuit board also having top and bottom surfaces with said top surface having some non-planar electrical components mounted thereon, said third circuit board mounted to said carrier such that it is positioned substantially back to back with said first circuit board with the bottom surfaces of said first and third circuit boards facing each other and spaced apart by said circuit board carrier.
Claim 8
Dependent Claim 114 words
A circuit board assembly according to claim 6 wherein said third circuit board is electrically interconnected with said first circuit board by a plurality of jumper wire elements extending therebetween and soldered to adjacent end portions of said first and third circuit boards and wherein said circuit board carrier has a second guide portion comprising a plurality of projections extending from an end of said carrier adjacent to said adjacent end portions of said first and third circuit boards, these projections forming notches therebetween with said jumper wires interconnecting said first and third circuit boards being positioned in associated ones of said notches and therefore being spaced apart from each other by said projections.
Claim 9
Dependent Claim 27 words
A circuit board assembly according to claim 7 wherein said circuit board carrier includes retaining tangs for contacting and mounting said third circuit board to said carrier.
Claim 10
Dependent Claim 63 words
A circuit board assembly according to claim 8 wherein said third circuit board has peripheral notches formed therein and said tangs which mount said third circuit board to said carrier are positioned in said peripheral notches in said third circuit board thereby mounting said third circuit board to said carrier and aiding in the positioning of said third circuit board on said carrier.
Claim 11
Dependent Claim 49 words
A circuit board assembly according to claim 1 wherein said carrier projections forming said carrier notches extend above said carrier raised peripheral shoulders and extend above and substantially perpendicular to the plane of said circuit boards whereby said projections assist in locating said jumper wires in said associated notches.
