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.
La force de pression, la vitesse de fonctionnement et le déplacement d'un bras d'essai sont commandés correctement selon le type de CI et le type de support. Ledit procédé consiste à mesurer la charge, l'accélération ou la vitesse, et le déplacement par poussée du CI, de sorte que la force de pression exercée sur le CI (5) placé sur un support (2) au moyen du poussoir (2) d'un bras d'essai (1), soit comparée avec une force de pression autorisée déterminée à partir de la constante de ressort synthétique du support (2) et du CI (5), et à commander le mouvement du bras d'essai (1) en fonction du résultat de la comparaison, de manière que la force de pression soit maintenue au-dessous de la force de pression autorisée.
