This method of connecting the coaxial cables 104, 106, 108 and the drain wire 114 may also provide an improved ability for flexing between the micro-camera 402 and the cable assembly 100. For example, camera systems that are used to view inside the human body often require that the camera system be able to bend and adjust according to a component inner diameter used to penetrate or diagnose a human body, such as a scope, catheter, guidewire, or flexible introducer sheath. Because of this, the cable assembly 100 may have to be flexible, both overall and in the area adjacent to the camera system where the two devices are coupled together. Vertical attachment of the coaxial cables 104, 106, 108 and the drain wire 114 may reduce back-end termination dimensions lessening the distance from the micro-camera 402 that the cable assembly 100 can be terminated or flexed independently from the micro-camera 402.

In an alternative embodiment, and referring now to FIGS. 1, 5A, and 5B, the source device may comprise a flexible, semi-rigid or rigid substrate such as a circuit board 502 having a first set of pads 504 positioned along an upper surface 510 of an edge portion 508 of the circuit board 502 and a second set of pads 506 positioned along a lower surface 512 of the edge portion 508. Again, due to the presence of the common drain wire 114, the cable assembly 100 may be connected to the edge portion 508 such that the ends of the coaxial cables 104, 106, 108 and an end of the drain wire 114 may be soldered or otherwise connected directly to the two sets of pads 504, 506 and eliminate the need for jumper wires.
