Abstract
Abstract An insulated baseboard has a power bus line and a ground bus line molded therein. Extending downwardly through the baseboard from the bus lines are wiring terminals. A plurality of openings are molded into the baseboard. Fitted into the openings are a plurality of contactors, the top ends of which have means to engage terminals of the integrated circuits, and the lower ends of which extend downwardly through the baseboards. On opposite ends of the bus lines are formed terminals for attachment to power supply and ground conductors.
