How to Use Double Sided PCB Board
A dual-sided PCB, also called a double sided PCB, is a PCB on which the front and back surfaces have been plated with conductive copper. There are two routing layers in a double-sided PCB as opposed to one routing layer in a single-sided board.
The layers are linked together by vias, small plated holes in which electrical connections between the top and bottom copper layers could be made. Understanding how to use double sided PCB board helps designers take full advantage of this structure. Having the knowledge of how to integrate a PCB board using a double layer and employing this method doubles the design space and improves the routing efficiency.
