Printed circuit boards are not typical end products and are somewhat confusing in the definition of names such as: the motherboard for a personal computer is called a motherboard and cannot be directly called a circuit board, and although the circuit board exists in the motherboard, the motherboard is different from the motherboard, so that the two aspects cannot be said to be the same when evaluating the industry. For another example: because of the integrated circuit components mounted on the circuit board, the news media is called an IC board, but it is not substantially identical to a printed circuit board. By printed circuit board we mean, in general, bare board-i.e., a circuit board without an upper component, multi-layer board, where more single or double sided wiring boards are used in order to increase the area over which wiring can be routed. A printed circuit board with two inner layers and two outer layers or two inner layers and two outer layers is made up through alternative arrangement of positioning system and insulating adhesive material, and interconnection of conducting patterns according to design requirement. The number of layers of the board does not represent that there are several independent wiring layers, and in special cases, empty layers are added to control the board thickness, and the number of layers is usually even and includes two outermost layers. Most motherboards are 4 to 8-layer structures, but technically, it is theoretically possible to make a PCB with nearly 100 layers. Large supercomputers mostly use rather many layers of motherboards, but since such computers can already be replaced by clusters of many common computers, supercomputers have become increasingly unused. Because the layers in a PCB are closely coupled, the actual number is generally less visible, but it is still visible if the motherboard is carefully viewed.
