Do I really need a soldering iron to solder SMD parts?
After last week’s episode about drag soldering, this new Elektor.TV selection is about soldering VS SMD components with a hot-air gun. Here the energy for heating the solder joint is conveyed by a hot gas, generally air. Although there is no mechanical contact with the component, heating is very efficient, but the temperature of any component will never exceed the air temperature adjusted on the station. With hot air soldering, cooling after reflow is rapid.
