PCB Online Order-10 layers impedance control

Conditions for impedance design: When a signal is transmitted in a PCB wire, if the length of the wire is close to 1/7 of the signal wavelength, the wire at this time becomes a signal transmission line. Generally, signal transmission lines need to be impedance controlled. When making PCB, decide whether to control the impedance according to customer requirements. If the customer requires impedance control for a certain line width, the impedance of the line width must be controlled during production.

When the signal is transmitted on the PCB, the characteristic impedance of the PCB must match the electronic impedance of the head and tail components. Once the impedance value exceeds the tolerance, the transmitted signal energy will be reflected, scattered, attenuated or delayed. , Resulting in incomplete signal and signal distortion.

Tips: Impedance control PCB board, the Impedance control process is free, and Impedance test is not free ,will charge 10% of the total price. Fuwwa PCB supplier in China. If you need place pcb order, please click Online Order immediately.
