Personnel Grounding

Grounding operators that handle ESD susceptible devices is one of the requirements for an ESD Control Plan. In fact, it is the basis of the ESD Association’s ANSI/ESD S20.20-2014 Standard. Grounding the body and maintaining maximum resistance to ground (Rtg) of less than 35 megohms prevents the operator from generating more than 100 volts.  The…

One of the tenants of a ESD Control Plan is controlling access to the ESD Protected Area. This is commonly accomplished by defining an area of a facility as the ESD Protected Area by taping off sections of the floor and placing signs to indicate that proper ESD control practices should be followed once an…

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…

Wave Distortion Technology continuous monitors feature low test voltage, a low monitor range for 1 megohm of resistance in the operator’s wrist strap, and instantaneous detection of an intermittent or failure of the path-to-ground of the operator or work surface that other monitors / technologies miss. How Wave Distortion Technology Works Applies a continuous test voltage…
