Double sided PCBs have two sided traces with a top and bottom layer. Assembler mount conductive copper and components on both sides of the circuit board, which allows the traces to cross over each other. This results in a higher density of circuits without the need of point-to-point soldering. For these types of circuit boards are more complex than single sided PCBs, it would be more difficult to produce.
However, the benefits of using double sided PCBs far outweigh the cons.
The double-sided PCB boards can add more components and have more space as needed. It can also reduce the circuit board’s size and use a more flexible design to make the most desired double-sided PCB board. And it can save cost better and achieve good circuit performance and heat dissipation function.
