ABSTRACT:
The present invention relates to a terminal which may be attached to a ceramic chip or other type substrate and which may be plugged into a PCB and thereby provide electrical connections between the substrate and the conductive traces on the board. More particularly, the terminal includes a receptacle for receiving the edge of a chip for mechanical retention and electrical contact, a spring member which protects the chip from thermal and mechanical stresses, means for insertion into a board's plated-through hole, and means establishing redundant short electrical paths between the pad on the chip and the traces on the PCB. Further, the terminal may be encapsulated in an elastomeric material which provides additional spring resiliency and also provides an environmental seal.
