Abstract:
A ball grid array socket connector adapted for electrically connecting an integrate circuit package assembly to a PC board, comprising:an insulative base having a top surface, a bottom surface and defining a plurality of cavities through the top surface and the bottom surface, the cavities being generally arranged in a matrix; a plurality of notches defined in the bottom surface of the base, the notches located at outer sides of the matrix of cavities; a plurality of stand-offs downwardly protruding from the bottom surface of the base and terminating at a plane generally parallel with the bottom surface of the base; a plurality of conductive contacts received in corresponding cavities of the base, each contact having a tail portion remained in the cavity; a plurality of solder balls attached to the tail portions of corresponding contacts, each solder ball having a bottom tip downwardly extending beyond the plane that the stand-offs terminate at before the solder balls heated and melted, and the stand-offs adapted to support the socket connector onto the PC board after the solder balls heated and melted; and a cover attached to the top surface of the base and defining a matrix of apertures, the cover being movable relative the base along the top surface of the base between multiple locations, the apertures of the cover being aligned with corresponding cavities of the base at one of the multiple locations.
