Use caution when soldering electronic components. The temperatures are 500 degrees and higher. Eye protection is required.

If you have a soldering iron with variable temperatures, it is a good idea to adjust the temperature for what is being soldered. Any soldering that is done in close proximity to solid state components should be done at a temperature below 600 degrees. Other wiring (motors, other hardware) can use a higher temperature.

There are various thicknesses of solder that can be used for the appropriate solder joint. A thinner solder wire is used for soldering smaller components.

Solder iron tips come in various sizes and texture. For the OpenROV a small tip with a straight edge at the end is recommended. This will allow you to solder smaller joints, while giving the tip some stability when heating the solder pads on the circuits.

You should heat the solder joint with the iron for approximately 5-10 seconds before putting any solder on the joint. The solder should run freely between the iron, the wire, and the solder pad. Once the right amount of solder is applied you should be able to remove the iron and see a nice shiny connection between the wire, and the solder pad.

If there are holes, major discoloration, or giant globs of solder everywhere, your connection between the wire and the solder pad may not take place and your electronics may not work properly.
