resistance to ground

The ESD Association‘s Resistance-to-Ground (Rtg) requirement for an operator wearing a wrist strap is < 3.5 X 107 ohms (ANSI/ESD S20.20). A wireless wrist strap will never meet this requirement. Wireless wrist straps claim to work by “making (a) body’s static electricity to discharge through discharge box.” Assuming that an operator was tribocharged to 10…

At this point in our blog series concerning ESD Awareness, we should ┬áconsider some basic physics: Ohm’s law is an extremely useful equation in the field of electrical/electronic engineering because it describes how voltage, current, and resistance are interrelated. Ohm’s law states that, in an electrical circuit, the current passing through a conductor between two…
