The pressing force, operation speed, and displacement of a test hand are properly controlled according to the type of IC and the type of socket. The method comprises sensing the load, acceleration or speed, and push displacement of the IC so as to compare the pressing force exerted on the IC (5) placed on a socket (2) by means of a pusher (8) of a test hand (1) with an allowable pressing force determined from the synthetic spring constant of the socket (2) and the IC (5), and controlling the movement of the test hand (1) according to the result of the comparison so as to keep the pressing force below the allowable pressing force.
