Self-Reflowing Circuit Boards Don’t Require Soldering Equipment

Carl Bugeja

Electronics engineer Carl Bugeja uploaded another great video the other day showing off his self-reflowing PCB.

He created a layer in the board with a long winding trace, so when power is added, it acts like a heating element. 9V of input voltage is enough to reach 165C (329F) and melt the solder.

Youtube / Phil’s Shop

From Phil’s Shop on Youtube:

“This video is showcasing a snow plow attachment I have been working on for my electric front loading cargo bicycle. It’s had a few hours use now and around 25 kilometers of total riding distance. The plow is easy to install and you can ride to your destination then drop the blade down and start plowing!”
