Hi Edgar, I am not aware of any standards either, but from own experience can tell that if there are boards going through oven with PPM between 1500-2000 the solder will be dark (unaesthetic) although some of our customers accepted them if they were

Good morning. What should be the Oxygen content Standard in an Oven? Here in my company, we have an ERSA reflow Oven, and we work with Lead Free solder paste. According to Work Standard documents send by my company corporate, the PPM Oxygen conte

Hi, I can verify that, and we have done 2 or more reflows with prototypes, using vapor phase reflow, and because there is no oxygen, the result is good, and you cannot tell the difference between the first reflow, and the 3rd. We are getting a vap

Hi, This would be a very exciting idea. Nitrogen is an inert gas, so this is why it's used, however Hydrogen mixed with oxygen in normal air is highly explosive, so it would be one of the worst gasses to use in a reflow oven I would think. Remember
