PCB Circuit Card Cloning
In the high speed PCB Circuit Card Cloning, this kind of issue won’t be too severe, and others could probably disaster. Such as signal establishment action among the transmission line from the inter-reflection can cause the signal oscillation and other component wrong trigger from printed wiring board reverse engineering quality assurance.
And the signal overshoot cause by the signal reflection can directly lead to time sequence misleading, even damage the components. Signal rising time will reduce to 1ns or below, while the cross-talk among the signals will become an extremely important issue. Cross talk is normally generate in the multilayer, high density printed wiring board copying, meanwhile the signal jumping could be very fast, decoupling among the lines will become easier to generate the cross-talk.
When signal rising time length less than 1ns, the high frequency harmonized wave can effortlessly decoupling to the adjacent signal line and generate the cross talk. As a result of that, if there is great amount of high speed interconnect signal line exist in the circuit card cloning, the system is more likely to face these issues.
High speed components come into being can make the signal rising time length less than 0.5ns, and causing designing system has more issues: power system stability issue and electro-magnetic interference issue. If the simultaneous frequency changing of data on the data-bus can probably cause the stability issue for power supply system, which will directly lead to the power supply surface surging and fluctuation, and big wave and fluctuation in the reference surface of system can affect the signal in the PCB card Cloning.
