Relative Susceptibility To Statics-Discharge Damage - Tektronix 2402A User Manual

Maintenance
7. Do not slide the components over any surtace.
8. Avoid handling components in areas that have a floor or work-surface covering
capable of generating a static charge.
9. Use a soldering iron that is connected to earth ground.
10. Use only approved antistatic, vacuum-type desoldering tools for component
removal.
