章节摘录

　　（2）Personal items such as plastic cups， thermos bottles， purses， sweaters， and other items of clothing should not be on work benches.　　（3）Care should be taken in handling of boards after mounting the e6mponents，and it may be noted that static damage may still result by improper handling of the stuffed boards.　　（4）At the soldering area， the operator is required to wear wrist strap well ground-ed through a 1MW. It is better to have a common ground for the test equipment and for the static-free work stations. Even if we provide a separate grounding for static-free workstations， it is highly likely that the ground wires short each other at some point or the other along their length. Therefore， it is recommended， if in doubt9 to check the equipment grounding thoroughly instead of going-in for a separate grounding.　　（5）Insulative brushes are used for flux application and cleaning. This may resultin generation of static leading to component damage. Use of cotton is recommendedwhile cleaning or for flux application.　　……
