  • Page 7 Bonding Bonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done through the use of a Field Service ESD kit. When connecting a bonding wire, always ensure that it is connected to bare metal and never to a painted or non- metal surface.
  • Page 8 Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage. Figure 3.

  • Page 9 Figure 5. Anti-Static Mat The wrist strap and bonding wire can be either directly connected between your wrist and bare metal on the hardware if the ESD mat is not required, or connected to the anti-static mat to protect hardware that is temporarily placed on the mat. The physical connection of the wrist strap and bonding wire between your skin, the ESD mat, and the hardware is known as bonding.
