Abstract
Abstract A combination of a potentiometer and an integrated circuit module are mounted on a printed circuit board which interconnects these members and provides for external connections. Mechanical mounting of the printed circuit board, the potentiometer, and the integrated circuit module is provided by a single mounting bushing of the potentiometer. The mounting arrangement also permits a heat sink tab on the integrated circuit to be clamped by this mounting bushing directly against the front panel of a user's equipment. Thus, the single mechanical mounting connection for the combination at the potentiometer bushing not only mechanically mounts all of the elements but additionally provides a heat sink connection for the circuit. At the same time, the use of the printed circuit board in this combination permits automated assembly and soldering which substantially reduces the cost of the circuit.
