The sub-assemblies of radio control transmitters (main circuit board, modules) are
fitted with electrostatically sensitive components. These parts can be destroyed,
suffer imperceptible damage or have their useful life shortened if static discharges
take place (potential equalisation through electro-static discharge) when the sub-
assembly is touched.
The following protective measures are essential if you have to handle
electrostatically sensitive sub-assemblies:
Before fitting or removing such sub-assemblies, equalise the electrical
potential difference between yourself and your environment (e.g. by
touching a heating radiator).
Open the basic device and touch it over a large area in order to equalise
the potential relative to the base unit.
Do not remove any sub-assemblies from their conductive anti-static bags
until you have equalised the potential. Avoid touching electronic components
or solder pads directly. Hold the sub-assembly by the edges of the circuit
board only.
Once removed from the basic device, the sub-assembly should only be
stored in the conductive anti-static bag in which it was delivered. Never allow
the sub-assembly to make direct contact with a conventional, non-ESD
compatible container made of foam, Styrofoam or other plastic.
