Hi Everybody: I have an "Iso-dryer" (a vapor "de-greaser" using isopropyl alcohol) ready to be replaced. It has been suggested that I replace it with a Marangoni drier. As I understand this system, a layer "atomized" mist of very small liquid droplets of isopropyl hovers over the top of DI wafer. As the wafers move from the DI water to the iso, the wafers are supposed to be dried. So far, I have talked to the vendor, Avid Technology, Mountain View, CA, www.Itechcorp.com Sounds like magic! Is anyone out there using such a system and are you happy with it?
