Reverse Engineering Printed Wiring Board for Signal Integrity

Reverse Engineering Printed Wiring Board for Signal Integrity

Signal Integrity is a very important issue in the process of reverse engineering printed wiring board, 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 for reverse engineering printed wiring board, then the engineer can assure the signal integrity is performed well in the printed wiring board reverse engineering. On the contrary, if the signal fails to response normally, it will reflect the signal integrity issue in the process of reverse engineering printed wiring board.

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 reverse engineering printed wiring 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 through printed wiring board reverse engineering. 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 printed wiring board reverse engineering 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.
