We have an ERSA Versaflow Ecoselect selective wave soldering machine. It works well except it needs nitrogen. You can't even move the table around if your nitrogen tank is empty. The spec sheet says Required degree of purity: Nitrogen liquid 5.0

I might be wrong since I don't know this piece of equipment but I think ROL might be a better measure. For 63/37 it used to be 20 ppm ROL (residual oxygen level) was about what you needed for a reflow oven. This is to take full advantage of all tha

I looked into nitrogen generators, it was 4 years back and I was trying to get 99.995 i think. About �20,000 for the generator then another �20,000 for the compressor you need to force the air in. I spoke with David Groome of BOC UK 01709 842358

100 PPM or 99.99% purity is sufficient for any soldering application. There are a number of manufacturers that make PSA style nitrogen generators that are great systems for electronics applications. They are low maintenance and will pay for themselve

The manufacterer of our machine recommends 99.999%. At their presentation before we purchased the machine they showed an example of using different purity levels. When they whiched the supply to 99.99 and then to 99.95 you can visibly see the diffe

Dave, can I assume that in the case(s) you're referring to, there was no gas introduced into the evacuation chamber to push any expelled moisture out of the system? In the industry I was involved with (implantable medical devices), we used nitrogen

What purity? To get 99.999% pure you will need dewers of liquid nitrogen or a two stage system. (and a dewer will last about a month and a half even if you don't use it as it outgasses.) But you can get reasonable purity with a wall mounted single s

Thanks Steve for mentioning the purity level .., Our purchase and sourcing team was asking us what is our expectation on purity level. Based on which they are checking with supplier. So wanted to know any standard which is followed for the same. R

I would like to know what purity is required for wave soldering process, I am doing an evaluation of buying/refilling tanks or installing a Membrane Nitrogen Generator. the generatos exist from 95% to 99.7% purity, does any one has done any analysis

What should be the ideal Purity level of Nitrogen at incoming stage ?? Please suggest. Regards, Ameen
