Environment test device

Abstract

Abstract PURPOSE:To effectively implement heating and cooling of an element by providing a heating element or a heat absorber to both the lower guide rail and the upper guide rail and moving one of them to press contact it against the semiconductor element. CONSTITUTION:When a stopper bar 6 is made to go up while a stopper bar 5 and a partition bar 7 are made to go down, only the element 1 at the far end is transferred and stopped at the stopper bar 5. Then an arm 10 is worked and the contact piece of a contact 9 is made to contact with the external lead wire of the element 1 and electric characteristics are measured. During this measuring period, the upper guide rail 23 built-in with a heating element 19 and a temerature detector 20 is made to go down along a fulcrum 24 and the element 1 is pressed against the lower guide rail to heat it. When the measurement is terminated, the arm 10 is worked to detach the contact piece 8, the stopper bar is made to go up and the elment 1 is discharged in a sorting box corresponding to the measured result. Thus, waste of the heat source is eliminated and the device can be arranged in a compact size and is simple.
