Innovative Drying Co., considered this possibility early in our experiments. The rate of chamber pump-down is not a consideration. However, the selection of the vacuum pump is critical. Avoid oil-sealed pumps at all costs. A poorly maintained oil-tra

Reflow ovens and wave solder machines come in a huge variety of flavors and price points. These machines tell the story of impressive features and capabilities such as flux management, gas flow management, static pressure control, active cooling zone

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

I am looking for an inertable reflow oven which will produce ROLs of less than 10 ppm. My current reflow oven will reduce oxygen levels to 10 ppm but only when using excessive nitrogen gas (4000 scfh). In reality less gas flow may reduce oxygen lev

All, Thanks for your quick response. However, my primary concern is not the question of solderability advantages of nitrogen versus air. With all things (zone temps, track speeds, flow rates, etc.) being equal, what would be the profile differences o

Nitrogen generators are becoming more popular than ever recently. They are being used for companies involved in food preparation, laser cutting and the electronics market to name a few. Purity, flow rates and pressure determine the system cost and va

Are you sure that you are getting adequate nitrogen flow up through the cap? If your pump isn't seated properly, you may have nitrogen escaping. Also, I have two different height nitrogen bases. The shorter one does not allow as much gas to escape
