Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are handled improperly, can result in intermittent or complete failures.

Following are guidelines for preventing ESD damage:

•Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin contact.

•When removing or installing a component, connect the equipment end of a ground strap to one of the two ESD connection sockets on the front edge of the upper card cage or to bare metal on the frame.

•If you are returning a replaced component to the factory, immediately place it in a static shielding bag to avoid ESD damage.

•The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.
