ABSTRACT:
An apparatus and method (200) for providing a hybrid circuit assembly carrier bracket are included wherein the bracket is constructed and arranged to provide controlled placement of at least a first power transistor (124, 126) and to provide a highly efficient thermal transfer and dissipating arrangement. The bracket is constructed and arranged to provide for placement of at least a first substrate for a hybrid circuit assembly thereon, and includes at least a first power transistor aperture (120, 122) with at least two bracket projections (146, 148) for permitting placement of said transistor on plural electrical contacts (104, 106). The heat generated by components on the circuit board(s) is transferred and dissipated substantially by biasing at least one bracket projection member resiliently against a heat sink (108, 110, 112, 114, 116, 118).
