Use only a grounded-tip soldering iron to solder or unsolder ESD devices.4. Use only an anti-static solder removal devices. 5. Do not use freon-propelled chemicals

38、.6. Do not remove a replacement ESD device from its protective package until immediately before your are ready to install it.7. Immediately before removing the protective materials from the leads of a replacement ESD device, touch the protective material tothe chassis or circuit assembly into which
