Printed circuit board (PCB) (oem pcb board manufacturer china) is the support of circuit components and devices in electronic products. It provides the electrical connection between circuit components and devices. With the rapid development of electric technology, the density of PGB is higher and higher. The quality of PCB design has a great impact on the ability to interfere. Therefore, the PCB design must comply with the general principles of PCB design, and should meet the requirements of anti-interference design. 


To make the best performance of electronic circuits, the distribution of components and the layout of wires are very important. In order to design a good quality and low cost PCB (china pcb manufacturer), the following general principles should be observed: 



First, consider the size of the PCB. When the size of the PCB (HDI pcb Printed circuit board) is too large, the printed line is long, the impedance is increased, the noise resistance is reduced, and the cost is increased; when the utility model is too small, the radiating is not good, and the adjacent lines are easily interfered. After determining the size of the PCB, determine the location of the particular element. Finally, according to the functional unit of the circuit, all the components of the circuit are arranged.
