Integrated circuit package connectors
Abstract
Abstract ELECTRICAL CONDUCTORS IN WHICH A FLAT INTEGRATED CIRCUIT PACKAGE IS HELD ON INSULATING BASE MEANS TO ENGAGE CONDUCTIVE PADS OF THE PACKAGE WITH FORWARDLY PROJECTING ACTIVE END PORTIONS OF CONTACT MEANS DISPOSED IN THE BASE MEANS. INITIALLY, THE ACTIVE PORTIONS ARE MOVED REARWARDLY, THROUGH BENDING OF A LATERALLY EXTENDING PORTION OF THE CONTACT MEANS, AND A HIGH UNIT CONTACT PRESSURE IS DEVELOPED AFTER WHICH THE ACTIVE PORTIONS ARE MOVED LATERALLY, THROUGH BENDING OF AN ANGULARLY EXTENDING PORTION OF THE CONTACT MEANS, WITH A WIPING ACTION UNDER THE HIGH UNIT CONTACT PRESSURE. THE CONTACT MEANS ARE DISPOSED IN TWO PARALLEL GROUPS FOR COACTION WITH PADS DISPOSED ALONG OPPOSITE SIDES OF A RECTANGULAR PACKAGE AND ARE ARRANGED IN A MANNER SUCH AS TO BALANCE LATERAL FORCES DEVELOPED FROM THE WIPING ACTIONS. THE PACKAGE IS HELD ON THE BASE BY HOLDING PLATE OR SCREWS, ENGAGING THE PACKAGE AT POINTS SUCH AS TO EQUALIZE CONTACT PRESSURES AND MINIMIZE STRESSES ON THE PACKAGE.
