If you create your circuit design on a breadboard, you may decide that you want to
make it permanent by soldering components in place on a printed circuit board (PCB). To

do this, you may have to get a universal printed circuit board, which in some ways is
similar to a breadboard layout. A prototyping printed circuit board has rows of individual
holes across them, much like all the pins on a breadboard. Generally, all the components
will go on the top of the board, and you solder underneath, and when you solder all the

wires, they usually go underneath also. This makes a much neater and cleaner board to
work with and can help avoid a lot of congestion if you are soldering a lot of components.
