Abstract:
A socket for removably receiving electric parts having a plurality of electrically conductive terminal balls disposed along a bottom surface thereof for testing such parts comprising:a base formed of electrically insulative material having a generally flat top surface,electrically conductive pins mounted in the base, the pins each having a leg received through an aperture in the base for connection to a circuit board,an electric part seating member having a bottom wall with a terminal receiving opening therein, the seating member received on the base,a contact film sheet received on the flat top surface, the sheet having a dielectric layer formed with electrically conductive terminal pads along at least one edge electrically interconnected with respective electrical contacts projecting upwardly from the sheet, the terminal pads electrically connected with respective electrically conductive pins and the contacts formed in a generally annular projection having a selected height and a selected outer perimeter relative to the size of the terminal balls such that the electrically conductive terminal balls of an electric part received on the seating member and extending through the opening in the bottom wall thereof will engage respective aligned electrical contacts at a peripheral location removed from the bottom most portion of the terminal balls with the bottom most portion of the terminal balls out of engagement with the electrical contacts.
