4.1.1.2 Operating Environment
(1)
Operators must wear anti-static
clothing and conductive shoes (or a
leg or heel strap).
(2)
Operators must wear a wrist strap
grounded to earth via a resistor of about 1 M
.
Soldering irons must be grounded from iron tip to earth, and must
be used only at low voltages (6 V to 24 V).
(3)
(4)
If the tweezers you use are likely to touch the device terminals, use
anti-static tweezers and in particular avoid metallic tweezers. If a
charged device touches a low-resistance tool, rapid discharge can
occur. When using vacuum tweezers, attach a conductive chucking
pat to the tip, and connect it to a dedicated ground used especially
for anti-static purposes (suggested resistance value: 10
4
to 10
8
).
Do not place devices or their containers near sources of strong
electrical fields (such as above a CRT).
(5)
(6)
When storing printed circuit boards which have devices mounted on
them, use a board container or bag that is protected against static
charge. To avoid the occurrence of static charge or discharge due to
friction, keep the boards separate from one other and do not stack
them directly on top of one another.
(7)
Ensure, if possible, that any articles (such as clipboards) which are
brought to any location where the level of static electricity must be
closely controlled are constructed of anti-static materials.
(8)
In cases where the human body comes into direct contact with a
device, be sure to wear anti-static finger covers or gloves (suggested
resistance value: 10
8
or less).
Equipment safety covers installed near devices should have
resistance ratings of 10
9
or less.
(10) If a wrist strap cannot be used for some reason, and there is a
possibility of imparting friction to devices, use an ionizer.
(9)
(11) The transport film used in TCP products is manufactured from
materials in which static charges tend to build up. When using
these products, install an ionizer to prevent the film from being
charged with static electricity. Also, ensure that no static electricity
will be applied to the product’s copper foils by taking measures to
prevent static occurring in the peripheral equipment.
