TRANSISTORS AND INTEGRATED
CIRCUITS
Transistors and integrated circuits should not be re­
placed unless they are actually defective. If unsoldered from
the circuit board during routine maintenance, return them to
their original board locations. Unnecessary replacement or
transposing of semiconductor devices may affect the adjust­
ment of the instrument. When a semiconductor is replaced,
check the performance of any instrument circuit that may be
affected.

Any replacement components should be of the original
type or a direct replacement. Bend transistor leads to fit
their circuit board holes and cut the leads to the same length
as the original component. See Figure 9-2 for typical lead-
configuration illustrations.
To remove a soldered dual-in-line packaged (DIP) 1C, do
not heat adjacent conductors consecutively. Apply heat to
pins at alternate sides and ends of the 1C as solder is re­
moved. Allow a moment for the circuit board to cool before
proceeding to the next pin.
