Abstract
A flexible printed circuit which includes a flexible substrate, a plurality of conductive pads, and a plurality of conductive traces that conductively connect to at least two conductive pads. The plurality of conductive pads and traces are defined on the flexible substrate. The flexible substrate has a first portion and a second portion. The first portion has at least two sets of conductive pads. The second portion has at least one set of conductive pads and is configured to conductively connect to a testing device. After the flexible printed circuit is tested, the second portion of the flexible substrate is detached from the first portion of the flexible substrate.
Claims20
A flexible printed circuit for an elongate medical device, the flexible printed circuit comprising:
- a flexible substrate with a first surface and a second surface including a plurality of conductive pads defined on the first surface of the flexible substrate and a plurality of conductive traces defined on the first surface of the flexible substrate, wherein the flexible substrate is folded around a portion of the elongate medical device;
- wherein the flexible substrate comprises
- a first portion,
- a second portion configured to detach from the first portion of the flexible substrate at a weakened area formed on the second surface of the flexible substrate and located between the first and the second portions, wherein the weakened area comprises a scored portion of the flexible substrate configured to promote separation of the second portion from the first portion, wherein the scored portion includes a portion of each conductive pad of the plurality of conductive pads, and
- at least two conductive pads located on the second portion of the flexible substrate are configured to conductively connect to a testing device, wherein the at least two conductive pads include a removable portion that is removed during the separation of the second portion from the first portion
- wherein the flexible substrate is defined by a first, distal edge, a second, proximal edge, a third edge, and a fourth edge, where the third and the fourth edges are adjacent to the first and the second edges and the third and the fourth edges are coupled with the first and the second edges.
