Electrostatic Discharge (ESD) Warning - Basic Information

NOTE: This article is intended for general information purposes

only.

INTRODUCTION

All Electrostatic Discharge (ESD) sensitive components

contain solid state circuits (transistors, diodes, semiconductors)

that may become damaged when contacted with an electrostatic charge.

The following information applies to all ESD sensitive devices. The

ESD symbol shown in Fig. 1 may be used on schematics to indicate which

components are ESD sensitive. See Fig. 1. Although different

manufactures may display different symbols to represent ESD sensitive

devices, the handling and measuring precautions and procedures are the

same.

Fig. 1: Sample ESD Symbol

HANDLING STATIC-SENSITIVE CIRCUITS/DEVICES

When handling an electronic part that is ESD sensitive, the

technician should follow these guidelines to reduce any possible

electrostatic charge build-up on the technician’s body and the

electronic part.

1) Always touch a known good ground source before handling

the part. This should be repeated while handling the part and more

frequently after sitting down from a standing position, sliding across

the seat or walking a distance.

2) Avoid touching electrical terminals of the part, unless

instructed by a diagnostic procedure.

3) DO NOT open the package of a new part until it is time to

install the part.

4) Before removing the part from its package, ground the

package to a known good ground source.

CHECKING STATIC-SENSITIVE CIRCUITS/DEVICES

1) Solid State circuits in electronic devices are shown

greatly simplified in schematics. See Fig. 2. Due to the

simplification of the electronic devices on the schematic, resistance

measurements could be misleading or could lead to an electrostatic

discharge. Always follow the recommended diagnostic procedure.

2) Only measure resistance at the terminals of the devices

when instructed by the recommended diagnostic procedure.

3) When using a voltmeter, be sure to connect the ground lead

first.
