A friend of mine is taking EE courses at Ivy tech (accredited). Every week, he calls me up with new Revelations in physics. 60/40 solder (rosin or acid core) is the best for electronics. He has a roll of 63/37 that the instructor tossed because "that's worthless for electronics". Apparently the instructor has a PHD in botany or some equally related field. But in the end, he'll have a degree! Fortunately, he's got me, and my loaner copy of AofE to keep him sane. _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
