The main role of the circuit board in PCB (Printed Circuit Board) design is to realize the transmission and control of electrical signals, as well as to provide mechanical support and protect electronic components. A circuit board is a substrate used to connect electronic components together. It is made of insulating materials, and conductive copper foil is laid on the substrate according to a predetermined circuit pattern. Conductive paths on a circuit board can be wires, connections between wires, and connections between component pins.
The design of circuit boards needs to consider factors such as the layout of conductive paths, the arrangement and connection of components, the width and spacing of lines, and the material and thickness of the substrate. Through reasonable PCB design, efficient transmission of electrical signals, reliable connections between components, and stable operation of the circuit can be achieved.
In addition, circuit boards also play a role in mechanically supporting and protecting electronic components. It provides a reliable mechanical foundation for electronic components, allowing the components to be stably fixed on the PCB and able to withstand certain mechanical stress. At the same time, circuit boards can also protect electronic components from environmental influences, such as waterproofing and dustproofing.
The circuit board plays a vital role in PCB design. It can realize the transmission and control of electrical signals, provide mechanical support and protect electronic components, thereby ensuring the stability and reliability of the entire circuit system.
