A socket for burn-in testing of an integrated circuit package having electrical leads. The socket includes an outer socket housing and an inner socket housing slidably moveable relative to the outer housing between an upper limit position and a lower limit position, the inner housing for supporting the integrated circuit package thereon and having a plurality of terminal-receiving cavities therein. The socket further includes a plurality of terminals disposed in the terminal-receiving cavities of said inner housing for contacting the leads of the integrated circuit package, a cam mechanism for raising and lowering the inner housing between the upper limit position and lower limit position relative to the outer housing, and a latch mechanism for holding and releasing the integrated circuit package relative to the inner housing.
