Removing the Board
You can remove the board from the enclosure to solder components into place. To remove the
board, complete the following steps.
1.
Disconnect the 100-pin cable from the SCB-100, if connected.
2.
Remove the grounding screws on either side of the top cover with a Phillips #1
screwdriver.
3.
Open the top cover.
4.
Loosen the strain-relief screws with a Phillips #2 screwdriver.
5.
Remove the signal wires from the screw terminals.
6.
Remove the board mount screws and 100-pin connector screws.
7.
Tilt the board up and pull it out of the enclosure.
Soldering, Desoldering, and Cutting Via Traces
on the SCB-100 Board
The applications discussed here require you to make modifications to the printed circuit board,
usually in the form of adding components or cutting jumpers. Use a low-wattage soldering
iron (20 to 30 W) when soldering to the board.
To desolder on the SCB-100, vacuum-type tools work best. Use care when desoldering to
avoid damaging component pads.
Use only rosin-core, electronic-grade solder. Acid-core solder damages the printed circuit
board and components.
For each screw terminal, there are one or two vias next to the silkscreen showing the screw
terminal number, as shown in the
SCB-100 Board Parts Locator Diagram
are shorted to the screw terminal so you can solder a component to the via to connect it to the
screw terminal signal.
The trace between each pair of vias can be cut if needed.
