WebAn optimal reflow profile is one of the most criti-cal factors in achieving quality solder joints on a printed circuit board (PCB) assembly with surface mount components. A profile is a function of temperatures applied to the assembly over time. When graphed on a Cartesian plane, a curve is formed that represents the temperature at a specific Web1. Flex PCB Soldering Correct Temperature. The general rule is that you should never use rigid PCB temperature profiles to reflow flex PCBs. That is because these temperatures are likely to be much higher than flexible PCBs can tolerate. Excessive heat during flex PCB soldering can lead to blistering and delamination.
