Handling devices that are sensitive to electrostatic discharge
Any computer part containing 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 handling the part are all at the same charge.
Note
Use product-specific ESD procedures when they exceed the requirements noted here.
Make sure that the ESD protective devices you use have been certified (ISO9000) as fully effective.
· When handling ESD-sensitive parts :
1. Keep the parts in protective packages until they are inserted into the product.
2. Wear a grounded wrist strap against your skin to eliminate static on your body.
3. Prevent the part from touching your clothing. Most clothing retains a charge even when you are wearing
a wrist strap.
4. Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially
useful when handling ESD-sensitive devices.
5. Select a grounding system, such as those listed below, to provide protection that meets the specific
service requirement.
Note
The use of a grounding system is desirable but not required to protect against ESD damage.
a. Attach the ESD ground clip too any frame ground, ground braid, or green-wire ground.
b. Use an ESD ground or reference point when working on a double-insulated or battery-operated
system. You can use coax or connector-outside shells on these systems.
c. Use the round ground-prong of the AC plug on AC-operated computers.
Ch1. Service information
Grounding requirements
Electrical grounding of the computers is required for operator safety and correct system function.
Proper grounding of the electrical outlet can be verified by a certified electrician.
