4. Only use an “anti-static” solder removal device. Some solder removal devices
not classified as “anti-static” and can generate an electrical charge sufficient to
damage ESD’s.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate
electrical charges sufficient to damage ESD’s.
6. Do not remove a replacement ESD from its protective packaging until
immediately before installing it. Most replacement ESD’s are packaged with all
leads shorted together by conductive foam, aluminum foil, or a comparable
conductive material.
7. Immediately before removing the protective shorting material from the leads of
a replacement ESD, touch the protective material to the chassis or circuit
assembly into which the device will be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into
which it will be installed, until completely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged replacement ESD’s.
Normal motions, actions such as brushing together of clothing fabric or lifting
one’s foot from a carpeted floor, can generate static electricity sufficient to
damage an ESD.
