If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Assumption of safe operation no longer possible must be taken,
- if the unit has obvious damage or
- if the unit no longer functions.
Under such cases, the unit must be shut down and secured against any
unintended operation.
1.7.1 Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can damage electrostatic-sensitive
devices or circuits. Adequate packaging and grounding techniques are essential to
avoid damage. Following precautions should be taken:
1.
Deliver printed circuit boards in electrostatic-safe containers such as cartons,
boxes or anti-static bags.
2.
Keep electrostatic-sensitive parts in their containers until they reach an
electrostatic-free station.
3.
Follow adequate grounding when a sensitive PCB, components, or assemblies are
touched.
4.
Store electrostatic-sensitive PCB’s in a protective packaging or on conductive
foam.
1.7.2 Grounding Method
Protect against electrostatic damage of the unit by taking the following preventative
measures:
1.
Cover workstations with approved anti-electrostatic material. Provide a wrist
strap connected to a working bench and properly grounded tools and equipment.
2.
For extra protection use anti-electrostatic mats, heel straps, or air ionizers.
3.
Handle electrostatic-sensitive components, PCBs, and assemblies with care
nearby the case or the edge of the board.
4.
Prevent contact with pins, leads, or circuitry.
5.
Switch off power and input signals before plugging and removing connectors or
test equipment.
6.
Keep the work area free from non-conductive materials such as ordinary plastic
assembly aids and Styrofoam.
7.
Use field service tools with conductivity, such as screwdrivers, pliers, and
vacuum cleaners.
8.
Always put drives and PCBs with the component-side down on the working
bench.
