Double sided printed circuit boards have become more and more popular in the PCB industry. Compare to single-sided PCB, and double side PCB is so complex that it can widely use higher technology electronics, vending machines, power supplies, led lighting, and many more applications.
Double sided printed circuit boards feature two sided traces with a top and bottom layer, while single side PCB has a conductive layer on one side of PCB. Double-sided PCB has a higher density without the need for point-to-point soldering since the PCBs can be mount conductive copper and components on both sides of the circuit board.
Double-Sided PCBs have two-sided traces, which provide many benefits for various applications. Here are a few advantages of using double-sided PCBs:
Relatively lower costs: Double-sided PCB has a lower cost than multilayer PCBs.
Increased circuit density: Double-sided PCBs can be added more components that effectively increase the circuit's density. It's better to have some components connected to the bottom side rather than all on one side.
More flexibility and reliability: Double-sided PCB comes with both the top layer and bottom layer, so you can use the bottom layer as a ground copper pour, which provides more flexibility. The reliability is very high because the holes are chemically cleaned and activated to ensure good plating and connection between the top and bottom layers.
Reduced board size: Using two sides instead of one also allows for a smaller board size overall, which can be important when building small-scale, integrated devices.
Double-sided PCB has circuit complexity and can be used in a wide range of applications. If you use single-sided PCB or multiplayer PCB, it will fail to meet the project's requirements. Applications of double-sided PCBs include (part of applications, not all):
