Nitrogen Generation for Semiconductor Manufacturing

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%.
