Soldering flux is (or at least, should be) one of the ubiquitous features of any electronics bench. It serves the purpose of excluding oxygen from a solder joint as it solidifies, and in most ...

For some of us the smell of rosin soldering flux vaporizing from the tip of an iron as a project takes shape is as evocative as the scent of a rose on a summer’s day. We’ve certainly breathed ...

Oxidation can negatively impact the conductivity and cause the solder joint to fail. To avoid this, use a rosin flux on the wire strands you solder together. Keep the tip of your soldering gun ...

However, for joints in the horizontal position, avoid directly preheating the top of the joint to avoid burning the soldering ...
