Background

Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. The printed circuit board is generally denoted as "PCB" and cannot be called "PCB board". Its development has been over 100 years old; the design of the method is mainly layout design; the circuit board has the main advantages of greatly reducing errors of wiring and assembly, and improving the automation level and the production labor rate. 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. The user typically uses an edge grinding machine to grind the edge of the printed circuit board.
