What is a Double layer PCB

The double layer PCB is a board with double sided wiring on the board.

Double layer PCB is an extension of single sided. When single layer wiring cannot meet the needs of electronic products, double layer PCB is used. Both sides have copper cladding and traces, and the lines between the two layers can be conducted through vias to form the required network connections.

The double layer PCB solves the difficulty of the single sided board because of the staggered wiring.

Double layer PCB have many advantages, such as easy and simple wiring, less labor-intensive wiring, and shorter line lengths.
