Handling Circuit Cards
WARNING
1-14
Although the risk of damage to an ESD is reduced considerably after
4.5
it is assembled into a circuit designed to protect sensitive components, take the
following precautions to reduce static charges to harmless levels:
•
Handle all circuit cards as ESDs unless they are known not to contain
electrostatic-sensitive parts.
Possibility of equipment damage. Heel straps are effective only while
standing on conductive or electrostatic-dissipative surfaces.
•
Wear wrist ground straps (PN 1AD012470001) before and while
touching or handling circuit cards containing ESDs.
•
Cover surfaces with resistance to ground in excess of 100 megohms,
such as ordinary tile, with properly grounded static dissipative
runners.
•
Store (even temporarily), pack, and ship circuit cards in antistatic
bags or containers.
•
Do not handle printed circuit board or components unnecessarily. Use
plastic handle.
•
Do not use synthetic bristled brushes or acid brushes to clean circuit
cards.
•
Handle failed circuit cards with same precautions as good circuit
cards.
