Abstract
Abstract A method of fabricating a folded printed wiring board assembly includes the steps of cutting an aperture into a rigid board; bonding a flexible circuit tape to one side of the board so that the tape bridges the aperture; perforating a plurality of holes through the board and flexible tape; inserting leads of electrical components through the holes; conductively bonding the leads to conductors on the flexible circuit tape; cutting two edges of the board through the aperture; and folding the assembly in the area of the aperture.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A method for fabricating a folded printed wiring board assembly comprising the following steps in the order named: cutting at least one aperture into a rigid board, bonding a flexible circuit tape to one side of the board so that the tape bridges the aperture, perforating a plurality of holes through the board and the flexible tape, inserting leads of electrical components through the holes, conductively bonding the compound leads to conductors on the flexible circuit tape, cutting two edges of the board through the aperture, and folding the assembly in the area of the aperture.
Claim 2
Independent Claim
96 words
A method for fabricating a folded printed wiring board assembly comprising the following steps in the order named: cutting at least one aperture into a rigid board, bonding a flexible circuit tape to one side of the board so that the tape bridges the aperture, perforating a plurality of holes through the board and the flexible tape, inserting leads of electrical components through the holes, conductively bonding the compound leads to conductors on the flexible circuit tape, cutting two edges of the board through the aperture, and folding the assembly in the area of the aperture.
Claim 3
Dependent Claim
40 words
The method as recited in claim 1 wherein the step of bonding the tape includes positioning of the tape so that the tape covers only the center portion of the aperture leaving an opening on each side of the tape.
Claim 4
Dependent Claim
35 words
The method as recited in claim 1 wherein the step of conductively bonding the component leads includes passing the side of the board having the flexible tape bonded to it through a molten solder bath.
Claim 5
Dependent Claim
31 words
The method as recited in claim 1 wherein the step of cutting two edges of the board includes shearing the two edges so that the shear lines run through the aperture.
Claim 6
Dependent Claim
25 words
The method as recited in claim 1 wherein the step of cutting two edges of the board includes cutting from each edge into the aperture.
Claim 7
Dependent Claim
42 words
The method as recited in claim 1 wherein the step of folding the board includes folding it so that the metallic conductors located on the flexible tape in the areas where the tape is folded are on the outside of each bend.
