Graham, When performing such a temperature variation test, do you attach the thermocouples so that they are in contact with the PCB's pads or are they reading the air temperature? If they are attached to the PCB, I take it you reposition the board

I personally would be wary of heller1707EXL and as I have many customers that find them not too repeatable due to cross profile variance... MarkIII not sure about. Always check perspective oven for this if you can...simple trick is to run blank PC
