2. Handling ESD-Sensitive Parts
NOTICE
Do not place the ESD-sensitive part on nonconductive material or on metal
tables/surfaces. If you must put down the ESD-sensitive part for any reason, then
first place it into the ESD bag.
NOTICE
Machine covers and metal tables/surfaces are electrical grounds. They increase
the risk of damage because they make a discharge path from your body through
the ESD-sensitive part. (Large metal objects can be discharge paths without being
grounded.)
NOTICE
If passing an ESD-sensitive part to another person, ensure both are wearing ESD
wristband and the ESD wristband is attached to the system grounding point.
NOTICE
Be extra careful in working with ESD-sensitive parts when cold-weather and heating
is used, because low humidity increases static electricity.
