Static control materials and devices
Use conductive bags and containers to store and transport circuit boards or
components. There are three common types of conductive bags: Velostat,
Tyvek and Pink Polyethylene.
Note: Pink Polyethylene is not recommended for ESD control.
Static-free work stations
Static-sensitive devices must be removed from packages only at a static-free
work area. The minimum equipment for a static-free work station is:
•
conductive bench mat
•
operator's conductive wrist strap
Ideally however, locations should be equipped as follows when necessary:
•
wrist strap
•
shoe grounding straps
•
ionized air blower (where required)
•
ground cord
•
floor mats
•
table mats
Where protective measures have not been installed, a suitable alternative
would be the use of a Portable Field Service Grounding Kit (3M part number
8012). This consists of a portable mat and wrist strap. The mat has pockets to
hold circuit boards.
Handling procedures
Degradation may occur at any time during the handling of electrostatic-
discharge-sensitive devices and components. Boards or components should
never come in contact with clothing, because normal grounding cannot
dissipate the static charges on fabrics.
Before handling static-sensitive equipment, personnel must discharge
themselves of any static charge. The most effective method is the use of a
grounded wrist strap combined with correctly installed ground static control
CAUTION
Electric shock hazard
Metalized or carbon bags are conductive and therefore must
not contact live electrical circuits, or they may cause shorting,
sparking, and shock hazards to personnel.
