A simple answer is never. Tin lead will oxidize when exposed to oxygen, but it will not rust away like normal steel. I have old equipment from the 1920�s and 1930� that have solder joints as robust as the day they were made. Maybe not as shinny, b

They have the extra benefit of providing oxygen enriched air at the filter site. We have had no problems and have had the filter for a couple years but we did get a second air compressor because of it. Hmm maybe I should go "inspect" it now. I"m f

Thanks, I am extremely new to this, in fact it's my first board that I am attempting to put together. I just needed an out put that pulsed between 0v-.09v. I am using it for an oxygen sensor simulator and found this diagram. I will try that site that

Hi! Just to update... we checked along with solder paste suplier and found that the curtain on the oven was probably causing the issue so we removed in order to troubleshoot, as far as I know this curtain helps to not allow to flow oxygen into the ov

Hello, I am currently in the process of purchasing a plasma chamber for the purpose of activating the surface of flex circuits so that they bond more readily. In addition I need to purchase a gas cylinder for the chamber, specifically one that is a

We all know that purity of nitrogen is critical for selective soldering. When it comes to wave solder- how much or what percentage reduction in oxygen is enough to make a difference in 1) at least reducing dross buildup and 2) being anble to cut ba

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

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
