Important The components of the circuit boards in the radios are
susceptible to damage from electrostatic discharges.
Observe anti-static precautions when handling the
boards or their components. Follow the procedures
given in the manufacturers’ data books.
Storage and Transport
of Items
Always observe anti-static precautions when storing, shipping or
carrying the circuit boards and their components. Use anti-static bags
for circuit boards and anti-static bags or tubes for components that are to
be stored or shipped. Use anti-static bags or trays for carrying circuit
boards, and foil or anti-static bags, trays, or tubes for carrying
components.
Anti-static
Workbenches
Use an anti-static workbench installed and tested according to the
manufacturer’s instructions. A typical installation is shown in Figure 4.1.
These benches have a dissipative rubber bench top, a conductive wrist
strap, and a connection to the building earth. The material of the bench
top must satisfy not only anti-static requirements but also the non-scratch
requirements mentioned above.
