For years, component level manufacturers and semiconductor producers have been using nitrogen inertion. Whether in the fabrication of stacked dies, rework, or component solder bumping, nitrogen gas allows for a larger process window in the safety of minimal oxygen. With the advent of mandated lead-free soldering, the critical issues of flux chemistry aggressiveness have again been raised. When this aspect of process control is coupled with the smaller Delta T temperature window, N2 inerting boosts production success.
Controlled nitrogen atmospheres in reflow, wave, selective, and rework applications give engineers a larger process arena to work in. Nitrogen also helps during the liquidous state while the solder is completing surface wetting for a good bond. We began testing PSA N2 generation with reflow and found that nitrogen purity levels required for reflow, wave and selective soldering range from 99.5% to 99.99%.
The production of semiconductors is one of the most delicate manufacturing processes. It involves a steady supply of nitrogen that is essential for reliable solder lines. Lead-free soldering is an industry requirement, and the nitrogen generation systems from On Site Gas can help you maintain consistent production at your semiconductor manufacturing site. High-purity nitrogen is used for all semiconductor and assembly processes, including reflow, wave, selection, and rework. A controlled atmosphere with the use of a nitrogen generator system can provide the production parameters that a semiconductor manufacturing operation demands.
A nitrogen generator on your assembly floor can help manage your nitrogen costs while eliminating the possibility of running out of pure nitrogen sooner than anticipated. A PSA nitrogen generator separates compressed air into a high-pressure stream of nitrogen and a low-pressure oxygen waste stream however this technology can also be used in lower purity applications. A nitrogen generator allows complete control over your nitrogen supply. A pressure swing absorption (PSA) nitrogen generation system can eliminate surface tension and dross issues in semiconductor manufacturing.. Our team can help you determine the most cost-effective nitrogen generation solution for your business.
Let us help you spec the perfect solution: on-time and on-demand. No matter what you’re looking for, we can design and build a nitrogen or oxygen generator to meet your needs.
