Its a flight controller for multicopters. Should i stick the wires from the top or bottom, and should i solder the top side or bottom side? I searched on youtube, but there is no definitive way to do it, and no great camera angle for me to see how exactly its done, and many use pin headers isntead.
Should i tin or not? That kind of thing. I know it normally has to be a cone shaped, but not sure if this applies here.
And lastly, how to keep it holding all that as i solder? Its much harder i imagine than soldering onto a pad. Use helping hands on the wires?
