Strictly speaking, double sided board is very important in the circuit board. Its use is very large. It is also very simple to see whether a PCB board is double sided board. I believe that people can completely understand single sided board . Double sided board is an extension of single sided board, meaning that the line of single sided board is not enough then turns to the opposite side, and an important feature of the double sided board is that it has through holes.
Simply, there are lines on both sides.In summary is: double sided lined board is the double sided board! For example, a board has lines on both sides, but only one side has electronic components, is it double layer PCB or single layer PCB? The answer is obvious,it is double sided board.
The difference between single sided board and double sided board is that single sided board has only one side of copper foil, and both sides of a double sided board are covered with copper foil, while the multilayer board is made of multiple sheets of copper clad laminates and bonded sheets. You can think of PCB as sheets of paper, and then you write on one side of a piece of paper,it is equivalent to pcb has lines on one side, so it is called single sided board. Double sided PCB is writing on both sides of the paper, it is equivalent of pcb that has lines on both sided,so called double sided board.(2 Layer Pcb)
