call me picky but doesn't hydrogen combust? maybe soemthing you could do is look at your process and your products and decide if you actually need to run in N2. Yes ok I can hear the crys now but seriously, for the vast majority of things if you have

We have a Nitrogen Silo. Your going to want to be careful if you decide to use nitrogen, not only are the levels unstable most of the time but it can also cause your components to tombstone like crazy, especially if you run a lot of LED's. We run 24/

It depends your product application and requirement. If high level, 100ppm required, or even 2000ppm is also ok. There should have sensor detecting O2 ppm inside reflow.

It depends on your product requirement, different application means different requirement.

I think the main driver is MTBF data driven by the Car OEMS, mainly german makers pushing this onto suppliers in supply chain. Vacuum soldering and void reduction is a hot topic for the leading electronics suppliers in Germany at the moment. Is not r

We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inordi
