Advantages of PCB circuit board

Printed circuit board {PCB circuit board}, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, and improve the level of automation and production labor rate.
According to the number of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multilayer circuit boards.
Since the printed circuit board is not a general terminal product, the definition of the name is a little confusing. For example, the motherboard used in personal computers is called the main board, and cannot be directly called the circuit board. Although there are circuit boards in the main board, They are not the same, so when evaluating the PCB industry, the two are related but cannot be said to be the same. Another example: because there are integrated circuit parts mounted on the circuit board, the news media call it an IC board, but in fact it is not the same as a printed circuit board. We usually say that the printed circuit board refers to the bare board-that is, the circuit board without upper components.
The main advantages of using printed boards are:
⒈Due to the repeatability (reproducibility) and consistency of the graphics, errors in wiring and assembly are reduced, and equipment maintenance, debugging and inspection time are saved;
⒉The design can be standardized to facilitate interchange;

3. The wiring density is high, the volume is small, and the weight is light, which is conducive to the miniaturization of electronic equipment;
⒋It is conducive to mechanized and automated production, which improves labor productivity and reduces the cost of electronic equipment.
The manufacturing methods of printed boards can be divided into two categories: subtraction (subtraction) and addition (addition). At present, large-scale industrial production is still dominated by the method of corroding copper foil in the subtractive method.
