Barry, Although I have not done a lot of wave and reflow oven profiling there are two other systems to consider. One is Datapaq and the is Kic. I use a datapaq for BGA profiling and I find it and it software to meet my needs. As far profiling wave and reflow a few things to consider are: Leading and trailing edges. Uniformity of heat across the circuit(s). Max temps for the assorted device (typically 210C +/-). Thermal Couple placement - critical devices (high pin count - BGA's); heavily populated area (leading and trailing edges). As far as tooling: Based on the complexity of the technology of the circuits your building you may want to consider using pallets, finger guards etc. I am not sure of the name of pallet mfg. some one else reading this may. Time vs Temp: Profiling in a nut shell is the achieving a temperature of +183C for about 30 to 60 across the circuit. The dwell time will vary depending on the circuit. The 30 to 60 second margin is what I use for BGA repairs. Fluxes and chemistries: Things to consider are spray versus bubble fluxers. No Clean versus RMA solder and fluxes.
