Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
A method of fabricating a printed wiring board comprising the steps of: supplying a substrate board having a designated linear connector edge; depositing a predetermined wiring pattern of electrically conducting layers on at least one surface of said substrate extending to said connector edge; depositing a second electrically conducting layer of material over the thickness of said connector edge; and trimming portions of said connector edge to remove portions of said second layer therefrom and thereby form edge contacts along the board thickness that are electrically isolated from each other.
Claim 2
Independent Claim
90 words
A method of fabricating a printed wiring board comprising the steps of: supplying a substrate board having a designated linear connector edge; depositing a predetermined wiring pattern of electrically conducting layers on at least one surface of said substrate extending to said connector edge; depositing a second electrically conducting layer of material over the thickness of said connector edge; and trimming portions of said connector edge to remove portions of said second layer therefrom and thereby form edge contacts along the board thickness that are electrically isolated from each other.
Claim 3
Dependent Claim
66 words
A method of fabricating a printed wiring board as in claim 1, wherein said substrate board is supplied with a plurality of elongated slots formed therein to define said linear connector edge for a plurality of smaller printed wiring boards, said steps of claim 1 are applied to each of said smaller printed wiring boards and a step of separating said smaller boards from each other.
Claim 4
Independent Claim
132 words
A method of creating a plurality of separate electrical contacts on an edge of a printed wiring board comprising the steps of: supplying a substrate board material having a designated linear connector edge; depositing a predetermined wiring pattern of electrically conducting layers on at least one surface of said substrate board extending to predetermined areas immediately adjacent said connector edge; coating said connector edge with a layer of electrically conducting material in a manner extend over the thickness of to said board edge and said adjacent portions of said wiring pattern layers; and trimming away a portion of said connector edge to electrically isolate said adjacent portions of said wiring pattern layers connected to said edge layer, leaving a corresponding set of edge contacts along the thickness of said printed wiring board.
Claim 5
Independent Claim
132 words
A method of creating a plurality of separate electrical contacts on an edge of a printed wiring board comprising the steps of: supplying a substrate board material having a designated linear connector edge; depositing a predetermined wiring pattern of electrically conducting layers on at least one surface of said substrate board extending to predetermined areas immediately adjacent said connector edge; coating said connector edge with a layer of electrically conducting material in a manner extend over the thickness of to said board edge and said adjacent portions of said wiring pattern layers; and trimming away a portion of said connector edge to electrically isolate said adjacent portions of said wiring pattern layers connected to said edge layer, leaving a corresponding set of edge contacts along the thickness of said printed wiring board.
Claim 6
Independent Claim
122 words
A method of interconnecting a plurality of printed wiring boards, comprising the steps of: providing a first board with a first predetermined conductor trace pattern exposed on one of its surfaces; providing an elastomeric connector strip across a portion of said exposed pattern; providing a second board with a second predetermined conductor trace pattern on at least one of its surfaces at least one linear edge, said second board contains a set of electrical contacts formed over the thickness of said one edge; orienting said second board to be approximately normal with respect to the first board; and compressing said elastomeric connector strip between said one edge of said second board and said exposed pattern of said surface of said first board.
Claim 7
Independent Claim
122 words
A method of interconnecting a plurality of printed wiring boards, comprising the steps of: providing a first board with a first predetermined conductor trace pattern exposed on one of its surfaces; providing an elastomeric connector strip across a portion of said exposed pattern; providing a second board with a second predetermined conductor trace pattern on at least one of its surfaces at least one linear edge, said second board contains a set of electrical contacts formed over the thickness of said one edge; orienting said second board to be approximately normal with respect to the first board; and compressing said elastomeric connector strip between said one edge of said second board and said exposed pattern of said surface of said first board.
Claim 8
Dependent Claim
44 words
A method as in claim 4, wherein said elastomeric connector contains a plurality of closely spaced and mutually insulated conductors within an elastomeric block, whereby several conductors interconnect each conductor trace patterned on said first board with the corresponding contact on said second board.
