Maintenance - FG 5010
Semiconductors
To remove in - line integrated circuits use an extracting
tool . This tool is available from Tektronix , Inc .; refer to the
Replaceable Mechanical Parts list for ordering information .
If an extracting tool is not available , use care to avoid dam
aging the pins . Pull slowly and evenly on both ends of the
integrated circuit . Try to avoid disengaging one end before
the other end .
Silicone grease must be used on the transistors attached
to the heat sink on the Output Amplifier board and the three
teminal regulator and the heat sink on the Sine Shaper
board . When replacing any of the eight transistors in individ
ual heat sinks on the output board make certain sufficient
silicone grease is inside the cup to contact the top and sides
of the transistor . If the individual transistor heat sinks are
removed
from
the large heat
sink , put a
layer of silicone
grease
between the two
heat sinks
.
The three
transistors
mounted
directly
to the
large heat
sink all have
insulating
washers
and
nonconducting
screws
attaching them to the large heat sink . If these transistors are
removed , coat both sides of the insulating washer with sili
cone grease . There is no insulating washer on the three
teminal regulator on the Sine Shaper board .
WARNING
Handle silicone grease with care . Avoid getting the
silicone grease in your eyes . Wash hands thoroughly
after
use
.
Interconnecting Pins
Several
methods
of
interconnection ,
including
square
pin
and coaxial cable , are used to electrically connect the circuit
boards
with
other boards and
components
.
Square
Pin
Assemblies
See Fig . 7-3 . The pins are of various lengths . They are
attached to each other with a plastic strip . To remove them ,
simply
unsolder from the
circuit board
.
Multipin
Connectors
The pin connectors used to connect the wires to the
interconnecting
pins are
clamped to the ends
of the wires .
To replace damaged multipin connectors , remove the old
pin connector from the holder . Do this by inserting a scribe
between the connector and the holder and prying the con
nector from the holder . Clamp the replacement connector to
the wire . Reinstall the conector in the holder .

If the individual end lead pin connectors are removed
from the plastic holder , note the order of the individual wires
for correct replacement in the holder . For proper replace
ment see Fig . 7-4 .

Magnetic Latch
Relays
To prevent damage to these relays , do not remove them
from the Output Amplifier , Sine Shaper , or Loop 1 circuit
boards unless
absolutely
necessary
. If the
relay
contacts
become noisy or the relay fails to operate , remove the two
