Static Discharge Precautions

Electronic circuit board and devices used on the truck can be
damaged by the discharge of static electricity, called
electrostatic discharge.
Static charges can accumulate from normal operation of the
truck as well as movement or contact between non-
conductive materials such as plastic bags, synthetic clothing,
synthetic soles on shoes, styrofoam coffee cups, etc.
Accumulated static can be discharged through human skin to
a circuit board or component by touching the parts. Static
discharge is also possible through the air when a charged
object is placed close to another surface at a different
electrical potential. Static discharge can occur without
seeing or feeling it.
Whenever working on or near static-sensitive electronics,
always use static discharge precautions.
1. Static-sensitive items are to remain in their
protective containers except when actually in use
at the static-free station.
2. Before removing the item(s) from their protective
container, the operator should place the container
on the conductive grounded bench top. Make sure
the wrist strap fits snugly around the wrist and is
properly plugged in/attached to ground receptacle
or the truck. The operator should then touch hands
to the conductive bench top, workstation, or truck.
3. All operations should be performed with the items
in contact with the truck or grounded bench top.
4. Do not allow conductive magazine (static-sensitive
items) to touch hard-grounded test gear or bench
top.
5. Ordinary plastic solder-suckers and other plastic
assembly aids should not be used.
6. In cases where it is impossible or impractical to
ground the operator with a wrist strap, a conductive
shoe strap can be used along with conductive tile/
mats.
