Abstract
Abstract A flexible jumper strip has a V-shape for the ends of its leads in order to increase its mechanical strength. In one embodiment the ends of the leads are folded back to give even more strength. In making the jumper strip conductor leads are formed on a conductor sheet laminated to an insulator sheet. Then the lead ends are given a V-shape with a mechanical punching device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
227 words
A process for making a jumper strip with pin-like lead ends comprising the steps of: laminating a conductor sheet and a smaller adhesive coated first insulation sheet together so that the conductor sheet extends beyond the area of the first insulation sheet in the area where the jumper pins are to be formed; etching the conductor sheet so as to form a conductor pattern from the conductor sheet, which pattern includes conductor leads ending in the area beyond the first insulation sheet, the conductor pattern in the area extending beyond the first insulation sheet also having a dam area connecting the leads, said dam area beginning at a certain distance from the first insulation sheet and ending at a certain distance from the end of the leads; folding the conductor pattern in the area of the dam so that the leads which were beyond the dam area rest on a portion of the leads before the dam area extending onto the first insulation sheet; forming a jumper pin at the end of each lead in the area beyond the first insulation sheet, said pins extending from a position on the first insulation sheet to the lead end, and imparting a V-shaped cross section to the pins in their transverse direction in at least part of those portions of the pins that extend beyond the first insulation sheet.

Claim 3
Dependent Claim
37 words
The process of claim 1, further including the step of laminating a second insulation sheet over the exposed conductor leads so as to encapsulate the portion of the folded-back leads overlying the leads on the first insulation.
Claim 4
Dependent Claim
57 words
The process of claim 1, wherein the step of forming a jumper pin and imparting a V-shape is carried out by punching a portion of the leads out of the folded dam area with a device that imparts a V-shape to at least a portion of that part of the lead extending beyond the first insulation sheet.
Claim 5
Dependent Claim
16 words
The process of claim 3, further including the step of applying solder to the jumper pins.
Claim 6
Dependent Claim
167 words
A process for making a jumper strip with pin-like lead ends comprising the steps of: laminating a conductor sheet and a smaller adhesive coated first insulation sheet together so that the conductor sheet extends beyond the area of the first insulation sheet in the area where the jumper pins are to be formed; forming a conductor pattern from the conductor sheet, which pattern includes conductor leads, by etching the conductor sheet on the first insulation sheet and not etching the conductor sheet in the area extending beyond the first insulation sheet; and forming a jumper pin at the end of each lead extending from a position on the first insulation sheet to the lead end and imparting a V-shaped cross section to the pins in their transverse direction by punching a portion of the leads out of the conductor sheet extending beyond the area of the first insulation sheet with a device that imparts a V-shaped cross section to at least a portion of the punched-out leads.
Claim 7
Dependent Claim
167 words
A process for making a jumper strip with pin-like lead ends comprising the steps of: laminating a conductor sheet and a smaller adhesive coated first insulation sheet together so that the conductor sheet extends beyond the area of the first insulation sheet in the area where the jumper pins are to be formed; forming a conductor pattern from the conductor sheet, which pattern includes conductor leads, by etching the conductor sheet on the first insulation sheet and not etching the conductor sheet in the area extending beyond the first insulation sheet; and forming a jumper pin at the end of each lead extending from a position on the first insulation sheet to the lead end and imparting a V-shaped cross section to the pins in their transverse direction by punching a portion of the leads out of the conductor sheet extending beyond the area of the first insulation sheet with a device that imparts a V-shaped cross section to at least a portion of the punched-out leads.
Claim 8
Dependent Claim
20 words
The process of claim 5, further including the step of laminating a second insulation sheet over the exposed conductor leads.
Claim 9
Dependent Claim
33 words
The process of claim 5, further including the step of laminating a second insulation sheet over the exposed conductor leads prior to punching a portion of the leads out of the conductor sheet.
Claim 10
Dependent Claim
38 words
The process of claim 6, wherein the V-shape extends to a portion of the etched leads on the first insulation sheet and the first and second insulation sheets encapsulate a portion of the V-shaped portion of the leads.
