Radio Frequency Effect Reduction of Printed Wiring Board Cloning

Radio Frequency Effect Reduction of Printed Wiring Board Cloning

In the process of printed wiring board cloning, we can see that the design frequency of the printed wiring board is becoming higher and higher. Accompany with the data speed increasing, the required bandwidth of data stream conveying can also promote the signal frequency upper limit to as high as 1Ghz or even higher after printed wiring board cloning. Although this high frequency signal technology has already exceeded the million-meter wave technology scope from Radio Frequency Effect Reduction of Printed Wiring Board Cloning (30Ghz), but it do refers to the Radio frequency and low level micro-wave technology.

Radio Frequency Effect Reduction of Printed Wiring Board Cloning engineering method must be able to handle the strong electronic magnetic field effect generated from the relative high frequency sector after printed wiring board cloning. These electronic magnetic field can have signals on the adjacent tracks or PCB tracks, and consequently lead to disturbing crosstalk such as interference or main noise, and will damage the systematic function if printed wiring board cloning. Return damage is mainly caused by the impedance mis-matchment, and the effect generated from the signal such as the additive noise and interference.

High return lost from printed wiring board cloning will have two kinds of negative effects, 1st is when the signal reflected from the signal source will increase the systematic noise, cause receiver become more difficult to distinguish the noise and signal if printed wiring board cloning; 2nd is any reflected signal can basically deteriorate the signal quality since the input signal’s shape will be affected and modified after Radio Frequency Effect Reduction of Printed Wiring Board Cloning.
