Reverse Engineering Electronic Circuit Board

Reverse engineering Electronic circuit board will refers to the mixed signals issue, especially for the current electronic consuming products, most of them have the mixed signals on the separated area after Electronic circuit board reverse engineering and Electronic circuit board designer should be aware of this point. As we all know, Electronic circuit board with mixed signal circuit which include digital circuit and analog circuit could be extremely complicate compare with other Electronic circuit board reverse engineering. The electronic component arrangement, Electronic circuit board layout as well as the power supply and grounding line treatment can directly affect the electrical performance and electro-magnetic performance after reverse engineering Electronic circuit board. So the engineers will sufficient experience can optimize the mixed signal Electronic circuit board reverse engineering and design features through the separation of ground and power supply circuit.

In the real Electronic circuit board reverse engineering work process, engineers will prefer to use the united, but actually Electronic circuit board will be separated into analog part and digital part, analog signals can be layout in all of layers of Electronic circuit board analog area, while digital signals can only be layout in the digital circuit area. In this situation, the reverted current of digital signals from Electronic circuit board reverse engineering won’t go into the ground layer of analog signals.

Only when layout the digital signals above the analog part of Electronic circuit board or layout the analog signals above the digital part of Electronic circuit board can emerge the interference of digital signals against analog signals after reverse engineering Electronic circuit board. The reason for interference on the analog circuit and signals is not because the ground hasn’t been separated, but the inappropriate layout of digital signals.
