ABSTRACT:
A chip carrier socket comprises a one piece insulating housing with a rectangular frame-like body portion surrounding a rectangular base-plate. Rows of contacts are force-fitted in cavities in the body portion with contact spring portions extending inwardly for electrical connection to leads on respective sides of a chip carrier inserted in the socket and with rows of soldering tabs extending inwardly at the circuit board engaging face for reflow soldering to pads of the circuit board. The base-plate is supported on the body portion with respective perimetrical edges thereof located spaced apart from the respective adjacent sides of the body portion, defining therewith apertures aligned over the respective rows of solder tabs, by bridge portions which extend between respective corners of the base-plate and adjacent respective corners of the frame-like body portion without obstruction of the field of view along the apertures. Circuit board engaging feet formed as continuations of respective bridges depend from corners of the base-plate for supporting the base-plate at a predetermined spacing above the surface of the circuit board. Chip carrier supporting projections upstand from respective corners of an upper surface thereof in a common, horizontal plane, at locations adjacent and diagonally aligned with the respective bridges.
