Resistors in Mat Ground Cords
Using a current limiting resistor in the ground cord is the user’s choice; however, the resistor is not for ESD control purposes. The ESD Association standard for grounding is ANSI/ESD S6.1. ANSI/ESD S6.1 recommends a hard ground (no resistor), but allows the use of a current limiting resistor in the mat’s ground cord. “The grounding…
