What should you do if after soldering the components you have noticed that the circuit is not working?

If the solder refuses to flow the way you want it to:

1. Stop and let the joint cool.
2. Clean and tin your iron.
3. Clean off any burnt flux from the joint.
4. Let the iron come back up to temperature.
5. Then reheat the joint and try again.

How do you fix a soldering mistake?

Soldering is pretty forgiving which makes it pretty easy to fix most any mistake you might make. If you apply a little too much solder or position a component incorrectly, you can reheat the joint, melt the solder and then reposition it correctly.

What is the importance of desoldering pump in repair?

A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. (An electrically-operated pump for this purpose would usually be called a vacuum pump.)

Do you have to remove old solder?

Unless the solder creates short circuits or structural problems, you can heat the solder until it melts, and then push your components through. The solder will still work. You will even get a connection to it. However, if the old solder will cause problems, then you have no choice but to remove it.

Should solder be reheated on a circuit board?

Should solder be reheated on a circuit board (keeping the same solder, not resoldering with new metal)? Yes, as many times as you want. Solder will always liquefy.

Can soldering damage components?

There are many types of soldering irons. It will take longer to heat the joint, allowing heat to spread to the component being soldered – potentially overheating and damaging the component. Longer heating times will also give more time for oxides to form on the surfaces being soldered.
