资料介绍

1) Some semi-conductive (“solid state”) devices are vulnerable to static electricity. These devices are known as ESD. ESD includes the integrated circuit and the field effect transistor. To avoid any materials damage from electrostatic shock, follow the instructions described below. 2) Remove any static electricity from your body by connecting the earth ground before handling any semi-conductive parts or assemblies. Alternatively, wear a dischargeable wrist-belt. (Make sure to remove any static electricity before connecting the power source - this is a safety instruction for avoiding electric shock) 3) Remove the ESD assembly and place it on a conductive surface such as aluminum foil to prevent accumulating static electricity. 4) Do not use any Freon-based chemicals. Such chemicals will generate static electricity that causes damage to the ESD. 5) Use only grounded-tip irons for soldering purposes. 6) Use only anti-static solder removal devices. Most solder removal devices do not support an anti-static feature. A solder removal device without an anti-static feature can store enough static electricity to cause damage to the ESD. 7) Do not remove the ESD from the protective box until the replacement is ready. Most ESD replacements are covered with lead, which will cause a short to the entire unit due to the conductive foam, aluminum foil or other conductive materials. 8) Remove the protective material from the ESD replacement lead immediately after connecting it to the chassis or circuit assembly. 9) Take extreme caution in handling any uncovered ESD replacements. Actions such as brushing clothes or lifting your leg from the carpet floor can generate enough static electricity to damage the ESD
