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

I am not aware of a "standard" I can tell you from experience that at

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

Hello Does anyone can give feedback about this two analyzers (zirox and delta f 150)? In fact we are trying to understand which is better for wave soldering, benefits and prejudice. Does anyone work with both? Thanks

Does anyone know the proper range of Oxygen PPM for no clean fluxes ?

We've had a customer request that we check the PPM level of oxygen at our wave solder's inerters. I'm looking on the web, and there seems to be a huge variety of these instruments. Can anyone make a recommendation on one that is working for you? T

fluctuating PPM is not the Nitrogen if you are using liquid Nitrogen. It is the Oxygen. Your problem is not with the Nitrogen flow, it is Oxygen getting in your oven.

Hi SMTnet. I have a series of sensitive parts and solder preforms which degrade when exposed to oxygen and moisture. It seems the standard way of protecting these components is to use a nitrogen purged cabinet as storage. This seems to use a lot of

Over time, copper in the via will form an oxide with oxygen in the air.
