Electrostatic Discharge
Protection
The procedures in this section require the handling of electrostatic
sensitive components. Microprocessors and other electronic
components can be permanently damaged by attempting repairs at
an unprotected workstation.
Use all electrostatic discharge (ESD) protection as described below!
1. Perform the disassembly procedure on an antistatic mat that is
grounded. Check the ground cable to insure that it is connected
to a good earth ground.
2. Always use a grounded soldering iron.
3. Wear a wrist-grounding strap.
4. The wrist strap and mat should both be connected through a
resistor (1 mega-ohm typical) to the same ground source.
5. Wrist-ground straps should be tested on a daily basis.
6. Components should be temporarily stored in metal or antistatic
containers. Never store components in plastic dishes.
7. Circuit boards should be stored in sealed antistatic bags or
covered antistatic boxes. Never store electronic boards directly
in cardboard boxes.
