Proper Esd Mat Grounding

Attaching all electrically conductive and dissipative items in the workplace to ground allows built up electrostatic charges to equalize with ground potential.

Proper esd mat grounding. Point to point resistance is 10 8 10 9 ohms and point to ground resistance is 10 5 10 6 ohms. The side that is blue gray or green the bottom surface is impregnated with carbon which is why it is black. Grounding mats add another layer of esd protection for your projects and offer conductive and dissipative options. Electrostatic discharge is no laughing matter.

Choosing to use an esd safe floor mat chair workstation and accessories ensure your workstation is a safe and functional space for handling sensitive products. Grounding an esd mat and wrist band at home. The simplest form of an esd mat is simply that a tabletop mat about the size of a placemat that you use on a desk table or any flat surface. Anti static mats are grounded by being placed on top of a conductive work surface or by using grounding cables to connect them to an electrical outlet.

A proper esd mat and strap have a resistive load to protect you from 110 voltage so it s not a direct ground path and yet can dissipate any static charge. A common point ground cord for grounding static control bench mats and wrist straps features a low profile head a 10 mm snap connection for mats two banana plug jacks and a 1 mw resistor. The cord is 15 long and equipped with an alligator clip or a ring terminal for customizing the cord length. They typically connect with a personal grounding wrist strap adding additional protection by drawing any esd charge away from the person working on the device.

In any case you should buy a simple outlet tester to make sure the outlet is correctly wired before connecting a mat to it and make sure to use this outlet for powering up any equipment your. The top surface is static dissipative. The discharge voltage can reach tens of thoushands of volts although it is low amperage. A grounded conductor cannot hold a static charge ansi esd 6 1 esd association standard for the protection of electrostatic discharge susceptible items grounding.
