Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic printed circuit cards are improperly

handled and can result in complete or intermittent failures. ESD can impair electronic circuitry and

equipment. Follow ESD prevention procedures when removing and replacing cards.

Following are steps for safely handling printed circuit cards:

Step 1 Slip on an ESD-preventive wrist strap, ensuring that it makes good skin contact.

Step 2 Connect the strap to an unpainted chassis frame surface or another proper grounding point

or chassis surface to safely channel unwanted ESD voltages to ground.

Step 3 Use the edge ejectors to remove the card. Handle the card by its sides. Place the card on an

antistatic surface or in a static shielding bag. To prevent further damage to the card by ESD

voltages, defective cards must remain in the static shielding bag when returned for repair

or replacement.

Step 4 Handling the new card by its edges only, insert it into the chassis. Avoid contact between

the card and clothing. The wrist strap only protects the card from ESD voltages on the body;

ESD voltages on clothing can still damage the card.

Note To ensure that the resistor in the ESD strap is providing proper ESD protection, use an

ohmmeter to check the ESD wrist strap. For adequate safety and ESD protection the measurement

should be in the range 1 to 10 mega ohms.
