The use of nitrogen in soldering is a 20-year-old practice that has gained popularity in all industrial sectors. Nitrogen gas is heated before passing to the soldering chamber to make it lighter so that it rises above oxygen and other gases present in the air. Wave soldering technology is applied for assembling PCB or Printed Circuit Boards of various electrical components. MVS Engineering provides a compact generator that produces nitrogen for wave soldering process.
Notable benefits of using nitrogen for wave soldering
Wave soldering technology is a useful process that starts with applying soldering paste to the surface where electrical components need to be soldered. Then a flux is applied to reduce the melting point of the solid substrate on which welding is supposed to be done. It makes the surface ready for single or double-wave soldering after heating it to a high temperature.
● The warmth of nitrogen gas helps in the transfer of heat between two waves of soldering on the circuit board.
● Nitrogen prevents the undesired oxidation of the metal surface of a printed circuit board. Thus, it contributes to the prevention of short circuits and other mechanical problems in the electrical circuit.
● Nitrogen also stops the corrosion of the circuit board by preventing the moisture from coming into close contact with the metal surface.
● The use of nitrogen is an eco-friendly process, mainly in using lead-free alloys in circuit boards of electrical devices.
● The investment in the installation of a nitrogen generator is worthy, as it makes the wave soldering process more cost-effective and even cheaper.

Wave soldering is applied only where it is essential for ensuring the longevity of electrical devices. The production of nitrogen for wave soldering is effective in keeping electrical components safe from damage. Thus, many electrical device manufacturers prefer to install a nitrogen generator on their production sites.
