What is Double-Sided PCB

A double-sided PCB, also known as a 2-layer PCB, features conductive copper layers on both the top and bottom sides. Unlike single-sided PCBs, which have components and traces on only one side, double-sided PCBs allow for the mounting of conductive copper and components on both sides of the board. This feature enables the creation of more complex designs and circuits.

Double-sided PCBs have closer routing traces. This is achieved by utilizing vias, which are small holes drilled onto the board and filled or coated with metal. Vias provide connections between the circuits on both sides of the board, allowing for the flow of signals and the establishment of interconnections.

Double-sided PCBs are commonly used in electronic devices that require more advanced and compact designs. By utilizing both sides of the board, manufacturers can optimize the use of space and create more efficient and sophisticated circuits. This makes double-sided PCBs suitable for a wide range of applications, including consumer electronics, automotive systems, industrial control systems, and more.
