Double Layer PCB (Printed Circuit Board) is a circuit board that has conductive copper layers on both the top and bottom sides of a single insulating substrate (usually fiberglass FR-4). Components and electrical connections can be placed and routed on both sides, allowing for higher circuit density than a single-layer PCB.
Consumer TVs, printers, power supplies, Industrial control boards, Automotive electronics.
Audio amplifiers and communication devices.
A double layer PCB offers a balance between complexity, performance, and cost, making it one of the most commonly used PCB types for medium-complexity electronic circuits.
Better signal routing flexibility.
Supports more complex circuits.
Improved electrical performance compared to single-layer boards.
Widely supported by PCB manufacturers.
