A simple idea (and somewhat wasteful of electricity) would be to duct off = a smaller pipe out of the stream and use that for SMD work >>> bfoz@TERRANDEV.COM 05/01/02 02:12PM >>> but lately I've been experimenting with using a heat gun that I originally bought for covering model airplanes. It gets plenty=20 hot, but the flow rate is way too high. Regardless, with enough patience, = I've used it to remove 44pin PLCC's (16F877). Unfortunately it's also hot enough to melt the plastic parts of=20 headers and db9 connectors. Any ideas on how to add a speed controller to my heat gun? It looks like a regular ac motor driving the fan, but I haven't taken it apart yet. I'm = worried that if I reduce the flow rate too much the coils with overheat, so maybe = I need to regulate those too. Maybe if I add a thermocouple and use a PIC to = regulate the fan speed and coil heating... -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu=20 -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
