Category:PCB PCB Layout
The connections on a PCB should be identical to its corresponding circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation.
I hope to find a good way to route differential pairs in the internal layers. Do you have some good methods for accurately calculating impedance on internal layers? (See More)
Is it good to use GND plane to be a positive layer? If not, do you know whether there are any negative effects in this plane routed of signals? And which is much better between negative layer and pos... (See More)
