GENERAL INFORMATION
Electrostatic Discharge (ESD) Warning - Basic Information
All Makes amd Models
* PLEASE READ THIS FIRST *
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
Page 595 of 1691
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.
Fig. 2: Sample Schematic Showing Typical ESD Sensitive Device
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.
