You must observe proper grounding techniques
to prevent the discharge of static electricity from
your body into ESD sensitive components.
|
Packaging materials
that contain ESD sensitive components are usually
marked with a yellow and black warning symbol.
To avoid damaging ESD
sensitive components:
- Handle
the components only after attaching a wrist strap
to your bare wrist. Attach the other end of the
wrist strap to a ground that terminates at the
system ground, such as any unpainted metallic
chassis surface.
- Handle
a circuit card by the faceplate or side edges
only. See How to Hold a
Circuit Card.
|
Ensure that your palm is not in contact with
the non component side of the board.
|
- Keep components away from plastics
and other synthetic materials such as polyester clothing.
- Do not hand components to another
person unless that person is grounded at the same potential
level.
- Hold devices such as a hard disk
drives in the same manner as a large circuit card. The
ESD sensitive area of these components is located on
the bottom surface.
