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

Kelvin, You can find the Standard acceptable levels and testing procedures from IPC. Here's a little advice from the fellas' over at PCFAB: As a guideline, we recommend that for assemblies processed with low-solids flux technology and that are not cl

No, none of us can tell you what is the acceptable level of halide content or contamination in flux residue. The level of harmful residues on your product helps determine the reliability of your product. We know nothing of your product, its custome

Biological Oxygen Demand (BOD). A test that measures how much of the oxygen dissolved in water is consumed by biological oxidation of the chemical in the water during the stated period of time. [Water from an exceptionally clear lake might show a BO

Is there a simple test available to test for lead content of solder. I don't need to know the specific amount. I just need to know if there is any lead present at all.

Maybe one of those test kits with lead detecting 'swabs'? Changes color when lead is present.

Dross removal is dependent upon the "activity" in your solder pot and the usage of a inert or an "air" atmosphere. The more moving that agitate the solder, the more dross. Basics first and then the answers will make sense. What is dross? Oxidatio

Hi guys! We just had our SnPb wave solder samples tested. However, the papers just gave us the contents and the percentage of each contents found with the sample. Does anybody know the passing range and/or paramters of the following elements: Pb, Cu,
