Reflow soldering allows for the simultaneous processing of multiple connections. This prevents the disconnection of wires while you are soldering their neighboring wires. Reflow Soldering also improves the quality of resulting PCB and offers many other benefits such as,
- Improved wettability of solder joints and surface mounted components.
- Improved solderability of a large variety of electronic components.
- Enhanced joint integrity for crucial electronic applications.
- Reduced board discoloration.
- Elimination of charred flux residues on heating elements and boards.
- Reduced formation of white haze from the oxidation of rosin or tin flux
- Optimized performance of low-residue and no-clean pastes.
- Enhanced flexibility of the process for accommodating a wide variety of operating conditions.
The type of soldering you choose for your PCB depends on a number of factors such as,
- Operating time
- Pad shapes
- Type of PCB
- Component orientation
You also need to consider the equipment you might need and the soldering environment. With that being said, we mostly use Reflow soldering when we have to manufacture products on a smaller scale. The products should be such that they don’t need a method amenable to cheap and fast mass production.
