Electrostatic Discharge Precautions
Caution –
Circuit board components are vulnerable to damage by electrostatic
discharge (ESD). An electrostatic charge can build up on the human body and then
discharge when you touch a board. Such discharge can be produced by walking
across a carpet and touching a board, or by other similar cause. Before handling any
board, ensure that you dissipate your body’s charge. Touch a conductive surface of
the chassis or other element connected to common earth ground to discharge the
static electricity present in your body.
To minimize risk of ESD damage:
■
Handle the board by the edges only.
■
Store the board in an antistatic bag.
■
Use a grounding strap and an ESD mat whenever you work on a board.
