Background

A printed circuit board (also known as printed circuit board or printed circuit board) is made up of insulating plate as basic material through cutting to a certain size, attaching at least one conducting pattern on it, and arranging holes (such as element holes, fastening holes and metallized holes) for replacing the chassis of electronic elements and realizing the connection between electronic elements. Such boards are known as "printed" circuit boards because they are made using electronic printing.

The circuit board can be divided into a single-sided board, a double-sided board, a four-layer board, a six-layer board and other multi-layer circuit boards according to the number of the layers of the circuit board. Since printed circuit boards are not typical end products, they 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 generally say bare board-i.e. a circuit board without upper components.
