<p>An electronic module (40,50,60,70) and method that enable circuitry required by one form of the module (e.g., a developmental unit (40,50,60,70)) to be omitted in a second form of the module (e.g., a production unit (80)), without necessitating additional changes in the module (40,50,60,70). The electronic module (40,50,60,70) includes a motherboard (44,54,64,74), a multichip module (MCM) (12) mounted to the motherboard (44,54,64,74), and a circuit unit (10,110) connected to the MCM (12). The circuit unit (10,110) comprises a flexible substrate (18), instrumentation circuitry (14) mounted on the flexible substrate (18), and a connector (16) coupled to the flexible substrate (18). The flexible substrate (18) has signal lines that electrically communicate with the MCM (12), the instrumentation circuitry (14), and the connector (16). A portion of the flexible substrate (18) is located between the MCM (12) and the motherboard (44,54,64,74) and permits electrical communication therebetween. The instrumentation circuitry (14) does not occupy space on the motherboard (44,54,64,74). <IMAGE></p> |
