ABSTRACT:
A flexible electrical connector (16) provides a circuit interface between the bent leads (12) of an integrated circuit package (10) and the respective circuit pads (14) of a printed circuit board (15). The integrated circuit package (10) is mounted on the surface of the printed circuit board (15), and the circuit interface has a substantially zero insertion force therebetween. The flexible electrical connector (16) has closely-spaced circuit traces (17) carried by an elastomeric core (18). The traces (17) accommodate the fine pitch of the leads (12) on the integrated circuit package (10); and the elastomeric core (18) provides a resilient "cushion" which compensates for irregularities or tolerance accumulations in the bent leads (12) as well as the different lead-bending specifications of the respective integrated circuit manufacturers.
