Proper Grounding Technique
RLTs and FSTs must follow proper ESD precautions. This includes the items
mentioned throughout this section: wrist straps, anti-static mats, anti-static
vacuum cleaners, and antistatic bags.
• FSTs in the field must be grounded by a wrist strap connected to the
terminal which in turn is connected to earth ground when servicing that
terminal and all boards being transported must be stored enclosed within
static-dissipative packaging.
• RLTs must work in a static-safe enviro
nment. The workbenches must have
anti-static mats which are connected to earth ground and the RLT must
observe proper ESD precautions, utilizing static wrists straps and proper
anti-static packaging.
Note!
Vacuum cleaners are generators of static electricity. When purchasing
a vacuum clea
ner, choose one with an antistatic nozzle (such as the
one recommended in the Spare Parts and Tools Chapter). If unable to
purchase antistatic vacuum cleaners, the nozzle of the hose must be
wrapped with antistatic (conductive) tape from the nozzle to the handle.
The picture below shows a properly grounded technician. Notice that the
technician is grounded to the anti-static mat and the mat is grounded to earth
ground at the AC outlet.
