ABSTRACT OF THE DISCLOSURE This invention relates generally to improved elec- trical connectors for mounting integrated circuit devices to circuit boards and the like and, more particularly to elec- trical connectors having improved covers for pressing the substrates on which the integrated circuit devices are mounted against electrical contacts of the connectors to insure good electrical connection. In prior connectors, the integrated circuit device is initially positioned in an in- sulator base and then secured therein by a rigid insulator cover. The base includes a plurality of individual metal contacts, one for each conductor pad on the integrated cir- cuit device substrate. The force with which each of the electrical contacts presses against the corresponding con- ductive pad on the integrated circuit device substrate may vary widely in some connectors due to manufacturing toler- ances of the contacts as well as variations in the thickness of the substrate within specified tolerance. This, in turn, may result in less than satisfactory electrical connection between one or more contacts and the corresponding pads. According to the present invention a resilient cover applies pressure at several points on a s?strate on which the in- tegrated circuit device is mounted ?o press the substrate against support surfaces in the connector base.
