I am a tinkerer lol and am getting into building racing drones. could you pls tell me where a good learning guide is for micro sodering?? I've been practicing on old boards and whatnot but when I try soldering a wire to the board the solder wants to ball up or not attach the wire. also is cleaning the board important? pls help its so frustrating!! lol and any general tips or tricks for soldering would be GREATLY appreciated friend
