Abstract
A method of manufacturing a guide plate for use in a chip carrier socket or other electrical connector provides the precision required for close-center line spacing while minimizing the cost associated with production. A block of ceramic or the like is ground to the precise outside dimensions required. Grooves are then cut in the block of ceramic, and the ceramic is then sliced into respective guide plates. The guide plates are inserted into openings provided in the electrical connector an retained therein. The grooves are dimensioned to cooperate with contact pins of the electrical connector to precisely maintain the pins in position, whereby when a chip is positioned in the electrical connector, the pins will be in position to make an electrical connection with the pads of the chip.
Claims8
An electrical connector assembly for electrically connecting a first substrate to a second substrate, the electrical connector comprising:
- a frame positioned on the first substrate having a plurality of contacts extending therethrough;
- a guide plate receiving opening positioned in the frame, the guide plate receiving opening has end portions of the contacts provided therein;
- a chip receiving opening positioned in the frame, adjacent to the guide plate receiving opening;
- a guide plate positioned in the guide plate receiving opening, the guide plate has side edges which have grooves provided therein, the grooves have silicone jelly provided therein;
- contact pins positioned in the grooves of the guide plate, the contact pins have first ends which electrically engage the contacts and second ends which extend into the chip receiving opening;
- whereby the silicone jelly provided in the grooves cooperates with the contact pins to maintain the contact pins in position to engage the second substrate when the second substrate is inserted into the chip receiving opening.
