Why do anti-static mats measure volume resistance?
As the infrastructure of the current electronic processing neighborhood, the anti-static table mat is an indispensable problem in the anti-static transformation. However, it should always be noted before use that the anti-static pad must be tested for its volume resistance. Generally, the testing equipment equipped by the factory itself is often only a hand-held simple testing device, and it basically only uses its surface resistance detection function, which is often ignored. crocodile mouth wire. When testing whether a batch of anti-static mats is a qualified product, not only the surface resistance, but also the resistance from the upper surface to the lower surface, that is, the volume resistance, can only be determined by passing the volume resistance esd table mat.
