Never do this. I mean it. It is dangerous, it is wrong, you may get hurt, your tools, your stuff or your house may be damaged. I did this because I didn’t have proper tools at hand and it was a do or die weekend situation. You must use proper air soldering and desoldering tools. In Youtube you can find excellent videos on how to do this in a better manner.
Bear in mind, I’m not suggesting you do this either, for all the reasons listed above. However, it is an interesting process to observe.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
hardcore… great find John
I know, right? Another item for the MacGuyver toolbox! 🙂
I’ve done this with a blowtorch before. It ruined the board but saved the $25 MCU that I was desoldering. I can’t imagine how you’d get the soot off the bottom of the board though.
