@Mike D posted:On a PC board the solder sucker is better. You don't have to heat the connection as long as you would with the solder wick which will minimize the possibility of damage to the board. For wires and terminals I just heat them up and pull them apart.
A soldering iron is much better than using a soldering gun for wiring and PC board work. The iron is smaller, easier to control, usually has a finer tip, is hot when you need it and operates at a lower temperature. In tight places you'll find the iron to be the better option.
Thanks Mike, sorry, I'm really referring to a soldering iron, not a gun, and it would've been to desolder/solder connections on the locomotive, but luckily, for the truck replacements, I don't need to, but for the motor, I'd need to, esp. if it's the motor itself or the worm screw. The don't leave much slack for the motor wire connections.
