ELECTROSTATIC DISCHARGE
Static electricity is an electrical charge which
can damage circuitry and components.
Listed below are important
E lectro s tatic
D ischarge guidelines for handling electronic
components. Following these guidelines will
avoid needless damage to circuit cards and
components on them.
•
Keep paper, non-conductive plastic, plastic foams or cardboard away from circuit
boards and components and static-free work areas.
•
Keep hand creams and food away from the conductive work surfaces. If spilled on the
bench top, these materials contaminate and increase the resistivity of the work area.
•
Be especially careful when using soldering guns around conductive work surfaces.
Solder spills and heat from the gun may melt and damage the conductive mat.
•
Check the grounding connections on wrist strap and static mats. (Mat must have proper
ground.) Make certain they fit snugly before starting work with the components and
printed circuit cards.
•
Touch the conductive work surfaces before starting work.
•
Know the ESD caution symbols.
•
Do not allow anyone not grounded to touch ESD sensitive components in the work area.
To be grounded, they must be standing on the conductive floor mat and must touch the
conductive bench top mat before touching the components or printed circuit cards.
•
Do not place ESD-sensitive components on work areas that are not grounded properly.
•
Do not touch the component by the pins or leads since the most damage is done at these
points by ESD. Handle the components by the cap edges or body and the printed circuit
cards by the edges.
•
Do not handle components or printed circuit cards during transport between work
stations. Components or cards must not be directly handled by anyone not grounded.
•
Do not use Refrigerant or other chlorinated cleaners at the work area. Use conductive or
anti-static bags and containers for storage and transportation of components or circuit
boards.
