Signal Integrity in the High Speed PCB Card Reverse Engineering
Signal Integrity is an importat issue to be consider when Reverse Engineering PCB Card schematic diagram, especially for the high speed PCB card, through proper improvement over the PCB card schematic diagram, engineer can improve the performance of signal integrity in PCB card;
When Reverse Engineering PCB card, signal integrity is a densely discussed subject, in this method, first of all, the signal transmitting model on the level of PCB card must be established base upon the high speed digital signal, and then through the understanding and computer analysis on the signal integrity which can affect the PCB assembled board Reverse Engineering quality to find the proper solution, and finally complete the Printed wiring board Reverse Engineering design file on the basis of it.
Accompany with the integrated circuit input/output switch speed and density of PCB card, signal integrity completeness has already become one of the most concerning issue in the process of Reverse Engineering PCB. As we all know, the parameters of components, PCB card; the layout of components on the PCB card, as well as the layout of high speed signals can deduce the signal integrity issue, and directly cause the system un-stability, even the total mal-functionality.
How to take fully consideration of signal integrity in the process of high speed Printed wiring board Reverse Engineering and take effective measures has already a popular topic in the PCB industry. The PCB card method which is base on the signal integrity computer analysis can effectively solve this issue.
