Make sure that the transistor leads
are formed as shown in Figure
8
so
that the leads can be soldered to
the printed .circuit pattern, starting
from the inner edge of the mounting
hole.
Solder the leads to the printed cir-
cuit pattern. Start at the inner
edge of mounting bole and solder the
remaining length of transistor lead
to the board. Use care not to use
excessive heat that causes the printed

CAUTION
---------------------~
Failure to solder the transistor
leads as directed may result in
the generation of RF loops that
could damage the transistor or
may cause low power output.
