Hey Hany: Here yago: On power outages: Talk about fun!!!! Can we have more of �em?? � You�re correct that a UPS to run your reflow is very expensive, but all you have to run is the belt motor. That�s "cheap!!!!" Get UPS sizing information from

Sure, the rolling action of the paste creates a weak magnetic field surrounding the paste. This is similar the field created by electric current flowing through a wire, as first described by James Maxwell. After creation of the magnetic flux, the m
