Electronics Manufacturing

Sparked by innovation in the assembly of electronic components, electronics have become smaller, lighter and less expensive. Currently, oxidation reaction, poor wettability and high peak temperature during soldering of printed circuit boards create harm to electronic solder joints. To offset these effects, using nitrogen to inert the atmosphere during soldering has become a globally accepted practice within electronics manufacturing.

Adapting to a fast-evolving market

To stay competitive in today’s market of electronics manufacturing, manufacturers must keep pace with evolving technologies, while reducing costs and navigating the latest regulations. Air Liquide has supported electronics manufacturing actors since the 1990s, with solutions for every step of their processes from assembly through testing, storage and cleaning.

Comprehensive solutions, equipment and audits

Our Nexelia for electronic manufacturing offer is a range of all-in-one solutions for the electronics manufacturing industry. While its main feature is nitrogen supply, it extends to application equipment and audit services. These are an important step as they assure our solutions best reflect our customers’ unique processes. Using the audit system, we are able to:

  • Measure the optimal inerting atmosphere inside the reflow oven
  • Ensure quality and safety with verification of the atmosphere in the oven, and conduct leakage checks
  • Optimize performance, including the quality of soldering and nitrogen consumption 

Core expertise in assembly

Assembly is the focused core process. In this regard we offer solutions to achieve controlled nitrogen atmospheres, thereby reducing the negative effects of oxidation for wave or reflow soldering. The Nexelia offer for electronics manufacturing includes the following solutions

  • Nexelia for wave soldering

Nexelia for Wave Soldering is a total retrofit solution to generate and carefully maintain an inert atmosphere during the wave-soldering process.

  • Nexelia for reflow soldering

Nexelia for Reflow Soldering was expertly designed by Air Liquide to generate and carefully monitor inert atmosphere into your reflow oven. The solution combines nitrogen supply with an automated controlling system to automatically adjust the inert atmosphere composition in the reflow oven.

  • Nexelia for cooling systems

Nexelia for Cooling Systems works by recycling the cold generated by liquid nitrogen vaporization back into your cooling system.

Application Equipment


INERTING HOOD-E is highly specific, patented equipment that diffuses nitrogen through plenums for optimal inerting of the solder pot and ensures a consistently low level of residual oxygen within the wave process.

In addition, hot nitrogen within the INERTING HOOD-E option increases the heat transfer to the PCB and avoids clogging of the nitrogen diffuser.

Atmosphere controller – E

A dynamic, patented automatic-control system, ATMOSPHERE CONTROLLER-E was expertly designed by Air Liquide for the careful monitoring of inert atmosphere into your reflow oven.

Water chiller – E

Highly reliable automated heat exchanger equipment, the WATER CHILLER-E was designed by Air Liquide for the efficient cooling of your reflow soldering process. Its system works by recycling the cold generated by the liquid nitrogen vaporization back into your cooling system and conveniently plugs into your water-cooling network.
