Once you've got the thermistor in the Onyx, I want you to spread the thermistor leads apart such
that each one crosses the center of a solder pad and then tape the thermistor in place using a short strip
of Kapton tape. This will keep the thermistor in place while you're soldering the leads to the pads.
Next, solder down the leads to the solder pads. Make sure you don't create a solder bridge
between the two pads. Use only enough solder to do the job. When you're done, clip off the excess
leads.
