High frequency circuit wiring is a key and difficult issue in PCB circuit board design. Let Shenzhen PCB manufacturers share with you the high-frequency circuit wiring techniques for PCB design:

　　1. The less alternating layers of leads between pins in high-frequency circuit devices, the better

　　The so-called "less alternating between lead layers is better" refers to the use of fewer vias (Via) during the component connection process. Reducing the number of vias can significantly improve speed and reduce the possibility of data errors.

　　2. The shorter the lead between the pins of high-frequency circuit devices, the better

　　The radiation intensity of a signal is proportional to the length of the signal line, and the longer the high-frequency signal lead, the easier it is to couple to components close to it.

　　3. The less bent the leads between the pins of high-speed electronic devices, the better

　　The lead wire for high-frequency circuit wiring should preferably be fully straight, and if a bend is needed, a 45 degree bend or arc bend can be used.

　　4. Pay attention to the "crosstalk" caused by parallel routing of signal lines in close proximity

　　High frequency circuit wiring should pay attention to the "crosstalk" introduced by signal lines running parallel in close proximity, which refers to the coupling phenomenon between signal lines that are not directly connected.
