soldering iron is too thick for proper access to these joints, you can use a piece
of solid wire to ‘extend’ the tip. Place the TAPIR on the bench with PCB 4 facing
down and solder the Cinch panel mount connector and PCBs 5, 6 and 7 to PCB 4.
Next fit PCB 2 in the same way as PCB 4. The tabs of PCBs 5 and 6 must fit
precisely in the notches. Press everything firmly together and solder the Cinch
connector end and the switch end. Check once again that everything is properly
mated and correct this if necessary. If everything is as it should be, solder the
joints between PCBs 2, 3 and 6 and between PCBs 2, 3 and 6.
Place the TAPIR on the bench with PCB 2 facing down and solder the joints between
PCBs 5, 6 and 7 and PCB 2. Check that
all
of the solder joints have been soldered
and no short circuits are formed, especially where PCB 2 and 6 meet.
Finally, solder the two M2x6 standoffs at the indicated locations on PCBs 5 and 6.
Ensure that they are flush against the board and precisely in the middle. Hold
them in place with clamping tweezers if necessary. If you have a steady hand,
you can also use a screw threaded into the standoff.
