Abstract
A test socket for an integrated circuit package having an upper housing and a lower housing secured to the top and bottom surfaces, respectively, of a load board. The upper housing having a cavity for receipt of the integrated circuit package and including a hole in the base of the upper housing to allow a plurality of solid socket plungers to contact test sites on the integrated circuit package. The socket plungers are positioned within a plurality of channels formed in the lower housing and extend through a plurality of holes in the load board to contact the test sites. A plurality of springs are positioned in the channels of the lower housing below the socket plungers to provide a spring force to bias the socket plungers upwardly toward the integrated circuit package. A nonconductive pushrod is positioned between the spring and a beveled edge of the plunger and a nonconductive cap is positioned above the load board for high frequency test signals. For closely spaced test sites a thinner daughter board is electrically connected to the load board through a hole in the load board. The test socket is then positioned on the daughter board.
