触子の改良に関するものである。[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement of a contactor for a semiconductor testing device (handler).

〔従来技術〕[Prior art]

, 4 is the holding jig for contact 1, and 5 is the fixing screw.
6 is a mold part of the IC to be measured, 6 is a lead part of the IC to be measured, and 7 is a handler rail.

Place the object to be measured so that the position of contact 1 is aligned with each of the
With the IC fixed, it is pressed in the direction of arrow A using the holding jig 4 of the contact 1 so as to contact the lead part 6, so that the lead part 6 and the contact 1 are brought into contact as shown in FIG. In this state, the lead portion 6 of each IC to be measured is connected to the test circuit through the contactor 1, and an electrical signal is applied from a tester (not shown) to perform electrical measurement of the IC to be measured.

しかしながら、このようなハンドラにおいては
下記のような欠点がある。 However, such a handler has the following drawbacks.

(1) 従来の接触子１と被測定ICのリード部６と
の接触は点接触となるため、大電流を流して電
気的信号を測定する場合、電気抵抗が大きくな
り易い。(1) Since the contact between the conventional contactor 1 and the lead part 6 of the IC to be measured is a point contact, when measuring an electrical signal by flowing a large current, the electrical resistance tends to increase.

(2) 接触性を良くするために、リード部６に対し
接触子１を強く押え付けると早く摩耗し、かつ
接触子１自体のバネの耐久性も弱くなり、押え
の強さのバラツキが生じ、正常な電圧を印加で
きない。(2) If the contact 1 is strongly pressed against the lead part 6 in order to improve contact, it will wear out quickly, and the durability of the spring of the contact 1 itself will become weak, resulting in variations in the strength of the press. , normal voltage cannot be applied.

大幅に低減せしめ、かつ耐久性をもたせることは
困難であつた。 Additionally, as shown in Figure 3, it is possible to increase the contact area by bending the end of the contact 1 to the lead part 6 of the IC under test, but this will also greatly reduce the electrical resistance and improve durability. It was difficult to give them sexuality.

て説明する。 This idea was made to eliminate the above-mentioned drawbacks, and aims to reduce the electrical resistance when a large current is passed by making surface contact between the contact and the lead part. . This idea will be explained below.

１の当たりの強さのバラツキがなくなる。 Next, the effect will be explained. When the metal piece 8 attached to the tip of the contactor 1 is brought into contact with the lead part 6 of the IC to be measured, the contact area is large, and depending on the angle at which the lead part 6 and the contactor 1 come into contact, the contact area is
As shown in FIG. 8, since the movable portion 8a moves smoothly and comes into contact with the lead portion 6, there is no variation in the strength of contact between each lead portion 6 and the contact 1.

た、面接触が得られることからサージによる突発
的な大電流に対しても接触子の劣化も少ない。 Furthermore, since the contact between the contactor 1 and the lead portion 6 is strong, the electrical resistance can be kept sufficiently low when a large current is passed, and stable voltage conditions can be obtained. Furthermore, since surface contact is achieved, there is little deterioration of the contactor even in the event of sudden large currents caused by surges.

い利点がある。[Effects of the invention] As explained above, this invention
In a semiconductor testing device that performs electrical measurements by applying electrical signals to each lead by contacting each lead, a metal piece is attached to the tip of the contact so that it can rotate freely and make surface contact. The metal piece rotates according to the shape of the lead part of the IC to be measured, that is, the angle at which the contact contacts the lead part, and stable surface contact is always obtained. Therefore, even when a large current is passed, the electrical resistance can be kept low, and stable electrical measurements can be achieved. In addition, since spring force or the like is not used as in the conventional case, there is an advantage that poor contact due to fatigue does not occur even after long-term use.
