Quality and Reliability Assurance / Handling Precautions

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 MΩ.

(3) Soldering irons must be grounded from iron tip to earth, and must

be used only at low voltages (6 V to 24 V).

(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: 104 to 108 Ω).

(5) Do not place devices or their containers near sources of strong

electrical fields (such as above a CRT).

(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: 108 Ω or less).

(9) Equipment safety covers installed near devices should have

resistance ratings of 109 Ω 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.

(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.
