| Can anyone please help me locate details on maximum allowable temperatures of components when passing through a reflow oven. | | I think I want the thermal profile for the part, or a source or standard which will allow me to check if I can safely

Hello all, Been doing some comparisons on joints made using the soldering iron versus reflowed solder paste (on a QFP package). The difference is quite significant: the joints made by the soldering iron are inconsistent and in many cases not filled
