PREPARATION
STEP 1
Follow all Safety Regulations
1 Eliminate
static
electricity
in the workplace by grounding operators, equipment, and devices
(components and computer boards). Grounding prevents static charge buildup and
electrostatic potential differences. Transporting products in special electrostatic shielding
packages avert electrical field damage.
2 An effective workplace should be outfitted with the following items:
a)
ESD protective clothing/smocks: Street clothing must not come in contact with
components or computer boards since the various materials in clothing can
generate high static charges. ESD protective smocks, manufactured with
conductive fibers, are recommended.
b)
Electrostatic shielding containers or totes: These containers (bags, boxes, etc.)
are made of specially formulated materials, which protect sensitive devices
during transport and storage.
c)
Antistatic or dissipative carriers: These provide ESD protection during
component movement in the manufacturing process. It must be noted that
antistatic materials alone will not provide complete protection. They must be
used in conjunction with other methods such as totes or electrostatic shielding
bags.
d)
Dissipative tablemat: The mat should provide a controlled discharge of static
voltages and must be grounded. The surface resistance is designed such that
sliding a computer board or component across its surface will not generate
more than 100 V.
e)
Personal grounding: A wrist strap or ESD cuff is kept in constant contact with
bare skin and has a cable for attaching it to the ESD ground. The purpose of the
wrist strap is to drain off the operator’s static charge. The wrist strap cord has a
current-limiting resistor for personnel safety. Wrist straps must be tested
frequently to ensure that they are undamaged and operating correctly. When a
wrist strap is impractical, special heel straps or shoes can be used. These items
are effective only when used in conjunction with a dissipative floor.
