Advantages of double sided pcb

Double sided pcb make it relatively easy to add conductive paths on the board, which means you will have a PCB that better suits your needs;
Since both sides of double-sided pcb board are conductive, a large number of ICs and components can be assembled at any time;
If necessary, the size of the circuit board can be reduced, because double-sided can be used, this type of PCB may save you money because you may only need to use one board;
Double-sided PCB can be used in many different applications and electronic products, double-sided PCB is ideal for demanding applications and advanced electronic products.
