Reverse Engineering Printed Wiring Board for Signal Integrity

Reverse Engineering Printed Wiring Board for Signal Integrity needs to optimize the layout design of original PCB board, through PCB reverse engineering process we can restore schematic and gerber file.

Signal Integrity is a very important issue in the printed wiring board design, which means the signals transmission quality on the wiring conductor of printed wiring board, and if they can be convey in correct time sequence and voltage response ability.

If the signal inside the printed wiring board wiring can reach the receiver in required time sequence, lasted time cycle and voltage range, then the engineer can assure the signal integrity is performed well. On the contrary, if the signal fails to response normally, it will reflect the signal integrity issue.

Signal integrity issues from High Speed printed wiring board reverse engineering include signals reflection, cross-talk, signal delay and time sequence in-correction.

The high speed digital system design analysis applied on the PCB board base upon the signal integrity analysis can not only increase the product features effectively, but also shorten the product development cycle, and bring down the development cost and budget.

In the case that digital system are all developed in the orientation of high speed and high density, it is quite necessary and hesitate to master this technology, engineers should keep on promoting the system in the aspect of signal integrity model and calculation algorithm, use the signal integrity to proceed the computer design and analyze the digital systematic design will be applied more widely and in wider range.

Anyway, signal integrity issue is commonly research topic in the high speed PCB reverse engineering. No matter in the aspects of design, tools, even the team cooperation and construction, all need to be modified when reverse engineering printed wiring board to ensure the normal operation of system is the final purpose of all of the technicians.
