11.3 ESD Handling Precautions
Any electronics device contains components sensitive to ESD (electrostatic discharge).
For example people experience up to 35kV ESD, typically while walking on a carpet in
low humidity environments. In the same manner many electronic components can be
damaged by less than 1000 volts of ESD. For this reason you must observe the
following handling precautions when servicing this equipment:
• Always wear a conductive wrist strap.
• Eliminate static generators (plastics, styrofoam, and so on) in the work area.
• Remove nylon or polyester jackets, roll up long sleeves, and remove or tie back
loose hanging neckties, jewelry, and long hair.
• Store and transport all static sensitive components in ESD protective containers.
• Disconnect all power from the unit before ESD sensitive components are
removed or inserted, unless noted.
• Use a static safeguarded workstation, which can be set up by using an anti-static
kit (Motorola part number 0180386A82). This kit includes a writes strap, two
ground cords, a static control tablemat, and a static control floor mat. The
Motorola part number for a replacement wrist strap that connects to the tablemat
is 4280385A59.
• When anti-static facilities are unavailable, use the following technique to
minimize the chance of damaging the equipment:
o Let the static sensitive component rest on a conductive surface when you
are not holding it.
o When setting down or picking up the static sensitive component, make
skin contact with a conductive work surface first and maintain this contact
while handling the component.
If possible, maintain relative humidity of 70-75% in development labs and service
shops.
