CIRCUIT BOARD PIN REPLACEMENT
A circuit-board pin replacement kit, including necessary tools, instructions, and replacement pins with attached spare
ferrules, is available from Tektronix.
CAUTION
Replace circuit board pins on multi-layer boards with extreme care. These boards
have conductive paths laminated between the top and bottom board layers. All
soldering, removal, and reinsertion of pins must be done with extreme care to
prevent breaking any electrical paths on the board.
Refer to Figure 6-2 while reading these instructions. To replace pins:
1.
Use a 15 W soldering iron to unsolder the pin while pulling it out of the board with a pair of pliers.
2.
If the ferrule remained in the board, carefully ream the solder out with a 0.031 inch drill. If the ferrule came out with
the pin, clean the excess solder out of the hole with a solder-removing wick and a scribe.
3.
If the ferrule remained in the board, remove the ferrule from the new pin and insert the pin into the old ferrule in the
same orientation as the old pin. If the ferrule came out with the old pin, insert the new pin with ferrule in the same
orientation as the old pin.
4.
When the new pin is properly positioned in the circuit board, carefully solder it on both sides of the board.
5.
Clean any remaining residue from the circuit board according to the instructions listed under Interior Cleaning.
