PCB, called printed circuit board in Chinese, is an important electronic component, responsible for PCB, called printed circuit board in Chinese, is an important electronic component, responsible for providing mechanical support for electronic components.Double-sided PCB As a carrier for the electrical connection of electronic components, it realizes the electrical insulation between various electronic components such as integrated circuits. In addition, PCB has the following important functions:.

1. PCB circuit board diagram, easy to find the specific location of components in the electrical schematic diagram, play the role of the electrical schematic diagram and the actual circuit board communication.

2. PCB circuit board diagram in the electrical schematic diagram shows the distribution and specific location of the components on the circuit board, and gives the direction of the connection line (copper foil line) between the pins of each component.

3. For repairers of enterprise equipment, PCB circuit board diagrams are very important repair technical information. the situation on the circuit board is drawn one to one on the PCB circuit board design diagram.

Four. PCBs also provide soldermask graphics for automated assembly, as well as logos and graphics for inserting, checking, and maintaining electronic components.

5. another major function of the PCB is to support circuit components and to interconnect them.

6. As electronic devices become more complex and require more parts, PCBs become more densely populated with circuits and parts.
