Reverse Engineering PCB Board Layout Methods

Reverse Engineering PCB Board Layout is a critical step, since in the whole procedures, this phase has the highest limitation, and need most delicate techniques with greatest amount of workload;

Layout drawing has been separated into three types: single side, double side and multilayer layout. And there are actually two types of Layouts: automatic layout and interactive layout,  before using automatic layout to Reverse Engineering PCB Board, it is necessary to use interactive way to proactively layout the wires with stricter requirement, and wires on the edge of input and output must avoid parallel in order to prevent any reflection or interference.

And add groundling wire for isolation if necessary, and the tracks on adjacent layers must vertical since parallel will have more chance to have parasite coupling; The yielding rat of automatic layout is firmly depended on the plan, and these rules can be pre-set include the quantity of curving, quantity of through vias as well as the stepping number, etc.

Normally the designer will layout the longitude track with an explosive attitude, and connect the short tracks swiftly. And then comes with Labyrinth tracks Reverse Engineering and optimize the track route while break-off those tracks which are already been drawed and re-connect them to improve the overall effect;

Refers to the high density PCB Board Reverse Engineering, through hole technique is not suitable anymore which waste a great amount of wire layout route, so in order to solve this issue, the blind and buried vias techniques have been introduced, which can not only fulfill the functions of the through hole but also save a lot of space for the routing so the PCB Board Reverse Engineering Process becomes more convenient, more smooth;
