  • Page 10 ESD protection is an increasing concern. Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in earlier Dell products. For this reason, some previously approved methods of handling parts are no longer applicable.
  • Page 11 Figure 7. Intermittent Do the following to prevent ESD damage: ● Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide adequate protection. Touching the chassis before handling the parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage.
  • Page 12 Figure 9. ESD field service kit Table 1. Wrist straps  Wrist strap and bonding wire Wireless ESD Strap (unacceptable) Figure 11. Wrist strap and bonding wire Figure 12. Wireless ESD strap (unacceptable) ESD Wrist Strap Tester The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is best practice to regularly test the strap prior to each service call, and at a minimum, test once per week.

  • Page 14 Figure 16. ESD packaging Transporting sensitive components When transporting ESD-sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport. ESD protection summary It is strongly suggested that all field service engineers use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products.
