AF3 Recommendations & Precautions

Recommended precautions include:

Handle the AF3 PROM by the case without touching its pins.

Use a static-free work station.

Wear a conductive wrist strap that has a minimum 200k ohms resistance and

is connected to earth ground.

Ground tools prior to contacting the AF3 PROM.

Connect static-free work station to ground through a minimum 200k ohm

resistance.

Control the relative humidity of the installation area - ideal conditions are

40% to 60% relative humidity.

The following is a list of things that should not be done:

Do not handle styrofoam, plastic, or cellophane-covered articles such as

combs, cigarette packages, and candy immediately prior to handling the AF3

PROM.

Do not hand the AF3 PROM to someone who is not antistatic protected.

Do not install the AF3 PROM in areas that might contaminate or foul the

pins of the AF3 PROM.

Do not handle the AF3 PROM by its pins.

Do not slide the AF3 PROM across any surface.

Do not place the AF3 PROM in a non-conductive plastic bag.

When these precautions are followed, the potential difference between the AF3

PROM pins is reduced thereby reducing the problems associated with static

discharges.
