LIF PGA socket and contact therein and method making the same

A LIF PGA socket for use with a PGA component comprising:

• an insulative housing having a plurality of cavities extending vertically therethrough;
• a top wall positioned at the top of each cavity having a small through-hole in the center;
• an engagement bar integrally attached on an underside of each top wall to form two opposite recesses beside said engagement bar in the corresponding cavity;
• and
• a plurality of contacts received in the corresponding cavities, respectively, each contact having a pair of spring arms for sandwiching a pin extending downward from the PGA component, a top tip of each arm of the contact being adapted to be received in the corresponding recess in the cavity, wherein
• said contact includes a base having two side walls perpendicularly extending from two side edges thereof, said pair of arms extending upward from a top portion of the side walls, respectively, each arm including a converging section to contact the pin of said PGA component and a diverging section to engage the engagement bar, and said contact further includes a reinforcement plate extending upward from an upper edge of said base, a slanted tip positioned at a top portion of said reinforcement plate, whereby the reinforcement plate incorporates the base to stabilize the contact in the cavity and the slanted tip of said reinforcement plate allows easy, guidable and reliable loading of the contact into the cavity from the bottom.
