5.1.1 Handling ESD boards
•
Electronic boards should only be touched/handled if absolutely
necessary.
•
Components/devices may only be touched/handled if
−
you are continuously grounded through an ESD arm band
−
or you are wearing ESD shoes or ESD shoe grounding strips.
•
The human body must be electrically discharged before
touching/handling an electronics board. This can be simply done by
touching a conductive, grounded object immediately beforehand (e.g.
bare metal cabinet parts, water pipes etc.).
•
Boards may not come into contact with highly-insulating materials
which can be statically charged-up - e.g. plastic foils, insulating
desktops, articles of clothing manufactured from man-made fibers.
•
Boards may only be placed down on conductive surfaces (desktop
with ESD surface, conductive ESD foam rubber, ESD packing bags,
ESD transport containers, board- or paper surfaces).
•
It is not permissible to bring boards close to monitors or TV sets.
5.1.2 Measuring and modifying ESD boards
•
Measurements may only be carried-out on boards if
−
the measuring equipment is grounded (via the protective
conductor) or
−
before making a measurement with an ungrounded instrument, the
probe must be briefly discharged (e.g. by briefly touching a bare-
metal control housing).
When soldering, only a grounded soldering iron may by used.
