Always use an ESD grounding strap when you are handling components that are subject
to ESD damage, and make sure that it is in direct contact with your skin.
If a grounding strap is not available, hold the component in its antistatic bag (see
Figure 55 on page 183 ) in one hand and touch the exposed, bare metal of the device
with the other hand immediately before inserting the component into the device.
WARNING: For safety, periodically check the resistance value of the ESD
grounding strap. The measurement must be in the range 1 through
10 Mohms.
• When handling any component that is subject to ESD damage and that is removed
from the device, make sure the equipment end of your ESD grounding strap is attached
to the ESD point on the chassis.
If no grounding strap is available, touch the exposed, bare metal of the device to ground
yourself before handling the component.
• Avoid contact between the component that is subject to ESD damage and your clothing.
ESD voltages emitted from clothing can damage components.
•
When removing or installing a component that is subject to ESD damage, always place
it component-side up on an antistatic surface, in an antistatic card rack, or in an
antistatic bag (see
Figure 55 on page 183 ). If you are returning a component, place it in
an antistatic bag before packing it.
