Abstract
In this paper we describe and demonstrate a unique termination scheme whereby an array of coaxial wires is efficiently fabricated into a monolithic substrate resulting in a two-dimensional array structure forming a pad grid array connector. This structure has significant implications for high density cable interconnect applications in ultrasound transducer systems, circuit board and hybrid interconnect structures. A connector concept is proposed in which the interconnect is used as an in-line connector for a user-friendly transducer probe interconnect system. Future applications of the connector are described including use as an integrated substrate onto which both one and two-dimensional arrays can be fabricated or connected. Results including electrical testing are shown for a 12.7 mm (0.5') diameter, 100 position, 0.6 mm (.25') center-to-center rectilinear pad array connector utilizing 40 gauge 50 (Omega) coaxial wires.
