Our solder irons are tuned to 700*F, but the in-use temperature varies according to the solder alloy and the characteristics of the board and components. Check some of the papers on multilayer ceramic capacitors. They get fairly specific, for insta

The soldering handbook that I use gives a 'rule of thumb' for best preheat temps for wave soldering. For multilayer brds that are metal core it suggests 110 to 130 degrees C topside temp to get the best solder fillet. We do a lot of multilayer meta
