Fluke 772 [15/26] Fluke corporation

Some semiconductors and custom IC's can be

damaged by electrostatic discharge during

handling. This notice explains how you can

minimize the chances of destroying such devices

by:

1. Knowing that there is a problem.

2. Learning the guidelines for handling them.

3. Using the procedures, packaging, and

bench techniques that are recommended.

The following practices should be followed to minimize damage to S.S. (static sensitive) devices.

1. MINIMIZE HANDLING

2. KEEP PARTS IN ORIGINAL CONTAINERS

UNTIL READY FOR USE.

3. DISCHARGE PERSONAL STATIC BEFORE

HANDLING DEVICES. USE A HIGH RESIS-

TANCE GROUNDING WRIST STRAP.

4. HANDLE S.S. DEVICES BY THE BODY.
