Abstract
An electrical socket comprises a dielectric base defining a plurality of receiving chambers therein, a number of terminals having a mating section and a soldering section, and a bottom board attached to the base. A dielectric cover is mounted to the base or is an integral part of the base for positioning pins of a mating integrated circuit (IC) chip. The bottom board is made of the same material as a mating circuit board. Thus, when the socket is soldered to the mating circuit board, misalignment between the terminals and the corresponding soldering pads of the mating circuit board is prevented due to identical coefficients of thermal expansion of the circuit board and the bottom board. The base forms a stand-off on a joining surface proximate the mating circuit board for distancing the bottom board from the base. Each terminal further comprises a curved section between the mating section and the soldering section for being disposed in a recess defined in a side wall of the corresponding receiving chamber of the base thereby cooperating with the stand-off to prevent molten solder from wicking into the receiving chambers. Thus, reliable communication quality between the mating IC chip, the socket and the mating circuit board can be achieved.
