I am interested in the optimum temperature for the soldering iron used in rework operations. At this moment we use 750F (Aprox. 400C) in the soldering irons for the touch up operation (Rework operation in line for wave soldering). Is it correct this temperature or do we use a lower temperature? *One consideration is the kind of flux you are using. If you are used to dealing with the old RMAs and their associated temperatures, then you are too hot for the low solids fluxes. I suggest that you contact Dave Robertson at Hexacon Electric. They did an extensive study a few years back on the effects of tip temperature with respect to various flux types.
