Circuit Soldering

“How can we attach two conductive wires together?”

 

Engineers commonly run into a problem. When working with circuits, we may need to extend our wire. However, it is physically impossible to do such a thing

 

Or is it?

 

Luckily for us, engineers can do the impossible. Let’s start with a few basic principles. We know that wires can conduct electricity. We also know that metal can also conduct electricity. And we also know that if we were to solidify a liquid that was between two objects it would connect the objects. So what if we were to take two circuits, expose their conductive centers, and then quickly melt some conductive metal between them to cause an attachment? Well, this is the process of soldering, which just so happens to be one of the most vital skills that any engineer needs to know.
