The surface of the so-called single sided PCB board and double sided PCB board is different in the number of copper layers. Both sides are copper on both sides of the board, which can be connected through perforation. Only a single layer of copper, it can only make a simple line. Holes can only be used to plug-in and they can't be turned on.
The single sided printed circuit board is usually made with copper foil laminate on one side, and the etching circuit pattern is made on the copper surface by screen printing or photolithography. The conductor pattern is formed by chemical etching to remove the excess copper foil.
Double sided printed circuit board has upper and lower two layers conductor figure, upper and lower through holes are connected by perforation. In the processing of printed circuit board, copper layer is board on the hole wall of perforation, and the upper and lower layers are conductive. The double sided printed circuit board is usually made with double sided copper foil laminate, and the corrosion resistance circuit pattern is made on the copper surface by screen printing or photo-imaging. A pattern of conductors is formed by chemical etching to remove excess copper foil.（pcb maker online）
