an indicator CCA A3 component (see figure 5-14) requires use of a
low-wattage (30 W or less) soldering iron and appropriate heat sinks.
Observe standard shop practices as well as general practices and pre-
cautions for CCA and microelectronic components while performing the
following steps:
Use a soldering pencil to solder all necessary points on
the CCA.  A soldering gun may cause overheating of CCA
traces, lead pads, or laminations.  overheating may cause
either pads or traces to lift from the CCA.  Subsequent
breakage is probable.
