  • Repairable electronic circuit package
    Patent number: 5424919
    Abstract: A dismountable, materially separable circuit package is made up by stacking pairs of heat sink, carrier, and bridge components in a back to back fashion. The package is mechanically clamped to form pressure clamped contact of the circuit components. Such piggy-back packaging reduces space requirements by approximately fifty percent. Pressure clamping provides a demountable, repairable structure.
