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.
