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'd speculate that the properties of a well formed solder connection processed in air and N2 are indistinguishable. Then again, the pitch is that N2 gives a wider process window, especially for NC flux-types. In the SMTnet Library look for: �Opti

Dave: In terms of heat transfer, air is 78% nitrogen, and the remainder is mostly (20.9%) oxygen (roughly the same molecular weight as nitrogen), with a bit of argon (0.9%), CO2, hydrogen, monosodium glutamate etc. So you would expect virtually no d

Less Oxygen... Less Oxidation Less Oxidation... Better Solderability

MK: If you are getting good product with air, here�s what you should do: * Turn off the N2. * Sell that N2 cracker machine. * Pat yourself on the back. * Go out for beers. [Not any of that Canadian Fosters crap, tho][Did you know that Ozzies do

We are using a nitrogen generator (with a N2 storage tank) that feeds 1 selective solder machine. I do not know which type of generator it is. The N2 generator has an oxygen analyzer on it. The selective solder manufacturer recommends a N2 purity

On our Pilarhouse Jade we use nitrogen to cool the belt that drives our solder pump as well as keep the amount of oxygen to a minimum in our solder pot to reduce dross.
