Pure nitrogen generation is one of the most critical aspects for the success in the selective soldering process, especially as a secondary solder process to electronic (s) PCBs that may have initially undergone reflow soldering. In some cases, reflow soldering is not the most effective option. Many electronic components are better suited for the selective soldering process, which offers a way to solder necessary parts for electronic devices or components that simply cannot sustain extreme heat associated with reflow soldering.
Nitrogen is an essential part of the selective soldering process. Soldering without a nitrogen atmosphere leaves solder joints open to the possibility of oxidizing. Individual components will not maintain the long term reliability expected in the harsh environments that today's circuit boards function This including everything from refrigerators to microwaves, mobile devices to satellites, military hardware to gaming consoles just to name a few.
Circuit board reliability during the reflow process is also tremendously enhanced in a controlled nitrogen environment. Reflow soldering in an "open air atmosphere" may result in the soldering of components that will not have long term reliability and often results in defects. These quality defects can be avoided by using a nitrogen generator to create a controlled nitrogen environment that results in an oven atmosphere with purity levels that meet or exceed industry standards.
At Gas Generation Solutions, we know if you are engaging in selective soldering, reflow soldering, or both, purity matters—that’s why our nitrogen generators for soldering offer purities of up to 99.9995%.
