Abstract
A preload cable comprises a cable, a first substrate, a bridge, a flyer, and a second substrate. The cable includes a pair of contacts. The first substrate includes a pair of conductors connected to the contacts. The bridge is positioned on the first substrate and is connected to the conductors. The flyer is positioned on the bridge. The second substrate is positioned adjacent to the first substrate and comprises a polyimide layer, and a hole extending through the polyimide layer and in alignment with the flyer.
Claims17
A preload cable comprising:
- a cable having a pair of contacts;
- a first substrate including a pair of conductors connected to the contacts;
- a bridge positioned on the first substrate and connected to the conductors;
- a flyer positioned on the bridge;
- and
- a second substrate positioned adjacent to the first substrate and comprising—
- a polyimide layer, and
- a hole extending through the polyimide layer and in alignment with the flyer,
- wherein the second substrate comprises a first surface that faces the first substrate and that includes a first fiducial formed thereon.
A detonator cable assembly comprising:
- a cable having a pair of contacts;
- a first substrate including a pair of conductors connected to the contacts;
- a bridge positioned on the first substrate and connected to the conductors;
- a flyer positioned on the bridge;
- a second substrate positioned adjacent the first substrate and comprising—
- a plurality of polyimide layers having a first surface adjacent the first substrate and a second surface opposite the first surface, and
- a hole extending from the first surface to the second surface and in alignment with the flyer;
- and
- a charge comprising explosive material positioned on the second surface of the second substrate,
- wherein the first surface of the second substrate includes a first fiducial formed thereon.
A method of forming a preload cable, the method comprising:
- forming a first substrate with one or more layers of polyimide;
- cutting a hole in the first substrate;
- ablating a portion of the first substrate to form a fiducial;
- aligning a second substrate using the fiducial of the first substrate, the second substrate including a bridge with a flyer positioned thereon;
- and
- attaching the second substrate to the first substrate so that the flyer is aligned with the hole of the first substrate.
