Principles of printed circuit board 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.
