Static-Sensitive Devices (SSD)
About SSD Handling Many electronic semiconductor devices (such as MOS ICs, FETs, optical
isolators, or film resistors) can be damaged by the discharge of static electricity.
Static-charge buildup is very common. Static discharges commonly occur when
the operator wears synthetic clothes and transfers the charge to any object
touched. These discharges can damage or destroy static-sensitive devices
(SSDs). In most cases, the discharge is not even perceptible to the person who
causes it.
To prevent static-discharge damage to SSDs, observe the following precautions
during any open-case test, maintenance, or repair procedures:
The SSD Symbol SSDs are identified with the following warning symbol:
Always perform repair or maintenance on a static-dissipative mat that is
connected to earth ground.
