Reflowing QFN-32 FTDI FT232RQ Chip:

First attempt to reflow a QFN-32 device to a board without purchasing expensive equipment. I used a hot air gun that I purchased on Amazon for $14 ( TruePower 01-0712 Mini Heat Gun, Blue). I also used solder paste that melts at 183C degrees.

Applied the solder paste:


Placed QFN-32 Device


Final Product being used to configure a CC430F5137 microcontroller
