A profiler can't distinguish where your heat is coming from, so if you're significantly imbalanced between top and bottom heat (could be an oven problem or your settings) it might still be a cause. You don't say whether or not your top and bottom s

You've replaced the sensors and cleaned any grease residue inside the Midas head, and you're still getting this error. You can check the connector on the little board, on top of the Midas, where the flex cable plugs in. I don't remember, off the t

Wolfgang: I agree that the IPC pads are reflow / top side wave solder. We run bottom-side PCLL at 45� to the wave with fairly involved solder thieves. Ta. Dave F
