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 ...

There are some very, very talented people out there, and they all work in the medium of wire, heat, and flux. At this year’s DEF CON, we opened the floodgates to competitive soldering.

The flux serves as a temporary adhesive to hold components onto the board until the paste is heated; after heating, a stronger physical bond is formed. Pastes are typically made of tin/lead alloys.

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 ...

The video below shows the application of flux on electronic components; here the flux is used to clean and prepare the PCB surface for reball soldering. Video credit: Xboxhaxorz Typically, organic ...

By applying heat and solder, you can fuse together conductive metal elements (such as wires) to create durable, permanent connections. Hobbyist soldering iron users might be interested in building ...
