How Circuit Boards Get Soldered In Seconds 😮

The components are pushed into the circuit board, and to connect them by hand, you would have to solder each one, which would take forever. Instead, you could dip the bottom into a special chemical, which cleans the wires. Next, hold it over a bath of melted solder, and as you lower it slowly, the solder touches Next, hold it over a bath of melted solder, and as you lower it slowly, the solder touches the wires underneath and sticks to them, fixing all the components in place at once.
