Only the manufacturer of this part can tell you if subjecting the entire assembly through reflow temps is okay. It is not a good assumption that "if a part can be hand soldered it can withstand reflow" there are many connectors/headers/buzzers/etc

If you have deep pockets and wish to spend alot of money over the next few years, then yes, call Metcal. Whatever solder iron you plan to use, it is my suggestion that you take a look at the board that you are going to solder. How big are the pads? H

Dave, I think you'll find you'll score higher if you add a cheeky half twist - you'll get a higher difficulty multiplier on your final score. Profiling is highly dependant on the quality of your oven, number of zones, temperature profiling tools et

If you already have trouble with two set commands, you will get many more when you add 3 more. Maintenance MUST learn to align the machines correctly. The BEC scenerio you describe proves that the alignment is wrong. The table can be adjusted for
