A double-sided PCB, also known as a 2 layer PCB, is a type of printed circuit board that incorporates conductive traces and components on both the top and bottom layers. Unlike single-sided PCBs that have components and traces on only one side, two-layer PCBs offer increased flexibility and design possibilities. By utilizing both sides of the board, designers can achieve higher component density, optimize space utilization, and accommodate more complex circuitry.
