Reducing ESD Damage

The following are suggestions that may help reduce the amount of ESD damage that can

occur during testing and servicing instruments.

PC Board Assemblies and Electronic Components

• Handle these items at a static-safe workstation.

• Store or transport these items in static-shielding containers.

CAUTION Do not use erasers to clean the edge-connector contacts. Erasers generate

static electricity and degrade the electrical quality of the contacts by

removing the thin gold plating.

Do not use paper of any kind to clean the edge-connector contacts. Paper or

lint particles left on the contact surface can cause intermittent electrical

connections.

Do not touch the edge-connector contacts or trace surfaces with bare hands.

Always handle board assemblies by the edges.

PC board assembly edge-connector contacts may be cleaned by using a lint-free cloth with

a solution of 80 percent electronics-grade isopropyl alcohol and 20 percent deionized water.

This procedure should be performed at a static-safe workstation.

WARNING Isopropyl alcohol is extremely flammable, causes irritation, may

cause eye damage, and is harmful if swallowed or inhaled. It may be

harmful if absorbed through the skin. Keep away from heat, sparks,

and flame. Avoid contact with eyes, skin, clothing. Avoid breathing

vapor. Keep in tightly closed container. Use with adequate

ventilation. Wash thoroughly after handling. In case of fire, use

alcohol foam, dry chemical, or carbon dioxide: water may be

ineffective. In case of spill, soak up with sand or earth. Flush spill

area with water.

Disposal Instructions: Dispose in accordance with all applicable

federal, state, and local environmental regulations.

Test Equipment

• Before connecting any coaxial cable to an instrument connector for the first time each

day, momentarily short together the center and outer conductors of the cable.

• Before touching the center pin of any connector and before removing any assembly from

the instrument, ensure proper use of a grounded, resistor-isolated, wrist strap.

• To prevent buildup of static charge, ensure that all instruments are properly

earth-grounded.
