Reverse Engineering High Speed PCB Board Signal Line must take the bending method of trace into consideration, the bending method of the trace must follow the relayout printed circuit board gerber file rule, avoid bending the signal lines as much as possible.
Reverse Engineering High Speed PCB Board Signal Line
If you have to bend the trace, do not trace it at an acute or right angle which is also an important reason for reverse engineering PCB board request, but rather use an obtuse angle.
When layouting high-speed signal lines, we often use serpentine lines to achieve equal length. The same serpentine line is actually a kind of bend. The line width, spacing, and bending method should all be selected reasonably, and the spacing should meet the 4W/1.5W rule.

If the distance between high-speed signal lines is too close, it is easy to produce crosstalk. Sometimes, due to relayout the circuit board circuitry pattern, board frame size and other reasons, the distance between our high-speed signal lines exceeds our minimum required distance, then we can only increase the distance between the high-speed signal lines as much as possible near the bottleneck. distance. In fact, if the space is sufficient, try to increase the distance between the two high-speed signal lines.
