INTEGRATED CIRCUIT PACKAGE HAVING COAXIAL PINS

摘要

An integrated circuit package comprises a multilayer ceramic substrate (1) for mounting a plurality of integrated circuit chips (2) on a first surface thereof, the multilayer substrate having a power supply layer (4), a ground connection layer (5) and circuit patterns (7) and means for connecting terminals (6) of the chips to the layers. An array of coaxial pins (3) is juxtaposed on a second surface of the multilayer substrate opposite to the first surface. Each of the coaxial pins comprises an inner conductor (8) and an outer conductor (9) surrounding the inner conductor (see Fig. 2). The inner conductor of one or more of the coaxial pins is connected to the power supply layer (4) and the inner conductors of the remaining coaxial pins are connected to the circuit patterns (7), the outer conductors of all of the coxial pins being connected to the ground connection layer (5).
