Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor chip components. The following techniques should b

Some solder removal devices not classified as anti-static can generate electrical charges sufficient to damage ES device

9、s. 5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrical

Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed.
