Abstract
An electrical assembly and actuating mechanism for use therewith in which conductor pairs of two circuit members (e.g., printed circuit board and electronic module or semiconductor chip) are effectively electrically coupled. A rigid plate is fixedly positioned relative to a first of the circuit members (e.g., using upstanding pins), a pressure plate is movably oriented relative to the rigid member, and an actuator (e.g., screw) moves within the rigid member to cause the pressure plate to engage the second circuit. Such engagement in turn causes the conductors of the second circuit member to forcibly engage the first circuit member's conductors. Solder balls and dendritic members can also be used for providing enhanced coupling without harm to either structures. The resulting assembly affords a low profile when in final position, as highly desired in the design of microelectronic packaging structures which the present invention is particularly related to. The invention also assures effective heat sinking of at least one of the circuit members.
