39. Such components commonly are called Electrostatically Sensitive ES Devices Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor chip components The following techniques should be used to help reduce the incidence of component damage caused by static by static electricity 1 Immediately before handling any semiconductor component or semiconductor equipped assembly drain off any electrostatic charge on your body by touching a known earth ground Alternatively obtain and wear a commercially available discharging wrist strap device which should be removed to prevent potential shock reasons prior to applying power to the Copyright 2008 LG Electronics Inc All right reserved Only for training and service purposes unit under test 2 After removing an electrical assembly equipped with ES devices place the assembly on a conductive surface such as aluminum foil to prevent electrostatic charge buildup or exposure of the assembly 3 Use only a grounded tip soldering iron to solder or unsolder ES devices 4 Use only an anti static type solder removal device Some solder removal devices not classified as anti static can generate electrical charges sufficient to damage ES devices 5 Do not use freon propelled chemicals These can generate electrical charges sufficient to damage ES devices 6 Do not remove a replacement ES device from its protective package until immediately
40. before you are ready to install it Most replacement ES devices are packaged with leads electrically shorted together by conductive foam aluminum foil or comparable conductive material 7 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 CAUTION Be sure no power is applied to the chassis or circuit and observe all other safety precautions 8 Minimize bodily motions when handling unpackaged replacement ES devices Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device General Soldering Guidelines 1 Use a grounded tip low wattage soldering iron and appropriate tip size and shape that will maintain tip temperature within the range or 500 F to 600 F 2 Use an appropriate gauge of RMA resin core solder composed of 60 parts tin 40 parts lead 3 Keep the soldering iron tip clean and well tinned 4 Thoroughly clean the surfaces to be soldered Use a mall wire bristle 0 5 inch or 1 25cm brush with a metal handle Do not use freon propelled spray on cleaners 5 Use the following unsoldering technique a Allow the soldering iron tip to reach normal temperature 500 F to 600 F b Heat the component lead until the solder melts c Quic
