Semiconductors
When replacing transistors requiring silicone grease
for heat transfer, replace the silicone grease as necessary.
To replace a damaged pin, first disconnect any pin
connectors. Then unsolder the damaged pin and pull it
from the board with a pair of pliers, leaving the ferrule in
the circuit board, if possible. If the ferrule remains in the
TM 9-6625-474-14&P-3
circuit board, remove the spare ferrule from the replace-
ment pin and press the new pin into the hole in the circuit
board. If the ferrule is removed with the damaged pin,
clean out the hole using a solder removing wick and a
scribe. Then press the replacement
spare ferrule, into the circuit board.
pin, with attached
Handle silicone grease with care. Avoid getting the
silicone grease in your eyes. Wash hands thoroughly
after use.
To remove socket mounted in-line integrated circuits
use an extracting tool. This tool is available from
Tektronix, Inc.; order Tektronix Part Number 003-0619-00.
If an extracting tool is not available, use care to avoid
damaging the pins. Pull slowly and evenly on both ends of
the integrated circuit. Try to avoid disengaging one end
before the other end.
Interconnecting Pins
Several methods of interconnection, including square
pin and circuit board pin and ferrule are used to electrical-
Iy connect the circuit boards with other boards and
components.
Several types of mating connectors are used for these
interconnecting pins. If the mating connector is mounted
on a PIug-on circuit board, special sockets are soldered
into the board. If the mating connector is on the end of a
lead, an end-lead pin connector is used. This connector
mates with the interconnecting pin. The following infor-
mation provides the removal and replacement procedure
for the various interconnecting methods.
Square Pin Assemblies
See Fig. 5-1. These pins are of various lengths. They are
attached to each other with a plastic strip. To remove them
simply unsolder from the circuit board.
Circuit Board Pins and Ferrules
See Fig. 5-2. A circuit board pin replacement kit
(including necessary tools, instructions, and replacement
pins with attached ferrules) is available from Tektronix,
Inc.; order Tektronix Part Number 040-0542-00. Replacing
circuit board pins on multilayer boards is not recommend-
ed. (The multilayer boards in this instrument are listed
under Soldering Techniques in this section. )
