ELECTROSTATIC DISCHARGE (ESD) HANDLING PROCEDURE
Magnetrol’s electronic instruments are manufactured to the
highest quality standards. These instruments utilize electron-
ic components which may be damaged by static electricity
present in most work environments. The following steps are
recommended to reduce the risk of component failure due to
electrostatic discharge:
1. Ship and store circuit boards in anti-static bags. If an anti-
static bag is not available, wrap board in aluminum foil. Do
not place boards on foam packing materials.
2. Use a grounding wrist strap when installing and remov-
ing circuit boards. A grounded workstation is also
recommended.
3. Handle printed circuit boards only by the edges. Do not
touch components or connector pins.
4. Ensure that all electrical connections are completely made
and none are partial or floating. Ground all equipment to a
good, earth ground.
