Electrostatic discharge (ESD) presents a significant danger to solid state
electronic components (semiconductor devices and PC board assemblies).
Static electricity can build on a variety of common objects (including
people) simply by handling or moving. ESD rarely results in immediate
failure of a component, but shows up later as an intermittent problem or
severely reduces the life of the component. All VARI*LITE equipment
uses solid state electronics and appropriate precautions to protect them
should be observed when servicing.
All parts in the following VARI*LITE part number groups should be con-
sidered ESD sensitive:
23- Electrical assemblies
24- Printed circuit board assemblies
80- Transistors
81- Thyristors
82- Diodes
83- IC’s:linear
84- IC’s:digital
85- IC’s:interface
86- Optoelectronic devices
87- Firmware
88- LED’s, displays
All PC boards should be shipped in electrostatic shielding bags. When
handling PC boards or components, devices such as conductive mats and
conductive wrist straps should be used whenever possible. If these precau-
tionary devices are not available, handling of PC boards and components
should be avoided.
CAUTION: Black foam (used to package solid state electronics) should
never be used for packing batteries or put in contact with PC boards which
contain batteries.
