The characteristics will be explained below. Sumime's chip varistors perform temporary gluing of the elements, and then pass them through a )-interceptor tank for die-cutting. At this time, the conductor 6 adheres to the outer edges of the electrode 2 of the chip-type varistor and the electrode 3 on the printed circuit board 4ν4, but since the electrodes 2 and 3 are in close contact, there is a gap V (A) between them. 3.As a result, the adhesive strength of chip-type varistors is always low, and the reliability of soldering is low.
