Abstract

A pluggable surface mount socket has been developed for use in mounting point-of-load dc-dc converters. The socket has high current (40 A) capability and low electrical resistance (ave = 0.67 mOmega). The resistance is stable with multiple mating cycles, humidity storage and thermal shock cycling. The socket does introduce additional length to the thermal path for heat removal to the motherboard. In the current application, heat is removed from the top of the dc-dc converter as well as through the socket and motherboard.
