Look just above the toaster oven in the last picture - these guys have a chipshooter, too!

I always try to profile using a fully populated board and soldering the thermocouples. This is the only true way of getting an actual temperature of the joints. But, with that being said, its not always feasible to use this. There have been a coup

You could probably make do with two as long as you attach to the smallest part in a sparsely populated area and a large heavy part in a densely populated area to cover both ends of the spectrum. When I had a MOLE I used all 6. Now I use the 3 the ove

How cute is that? We and Earl Sir Moonbeam were using those electric fry pan 'hot plate' things years ago. Look here: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=10155 Haters, turn down the volume.
