Handling ESD-sensitive devices

Any computer part that contains transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur when
there is a difference in charge between objects. Protect against ESD damage by
equalizing the charge so that the machine, the part, the work mat, and the person
that is handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements noted
2. Make sure that the ESD protective devices that you use have been certified
Use the following precautions when handling ESD-sensitive parts:
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people.
v Wear a grounded wrist strap against your skin to eliminate static on your body.
v Prevent the part from touching your clothing. Most clothing is insulative and
v Select a grounding system, such as those listed below, to provide protection that
