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.
