In fact, the above principles need to be applied flexibly in the laminated design. Sometimes not all principles can be met at the same time or all principles can be applied optimally.
The current approach is to increase the distance between the two signal layers and make the lines of the two layers as vertical as possible to avoid signal crosstalk between layers.
With the combination of soft and hard technology, designers can interconnect multiple PCBS in a single package without the need for connectors, wires and cables.
The inner laser hole needs to be electroplated and filled, and then the outer laser hole is made. The price is more expensive than the error hole.

This simple statement connects the common sense of capacitance with the newly discovered theory of characteristic impedance.
Circuit board bubbling is actually the problem of poor binding force on the board, and then by extension, the surface quality of the board, which contains two aspects，
the traditional aluminum sheet plugging process is changed, and the plate surface welding and plugging are completed with white mesh. Stable production and reliable quality.
Many customers use pad(plug-in holes) to represent conductive holes, thus causing your conductive holes to open the window. Then please check your document design!
In the real world, in addition to considering signal quality, power source plane coupling (using adjacent ground planes to reduce AC impedance of the power plane) and layered symmetry are all factors to be considered.
When selecting the driver chip, in addition to ensuring that it basically matches the load and that the signal edge meets the requirements (generally, the clock is an effective signal along the clock), the time delay of the clock in the driver chip should
RC filtering is that the resistance itself consumes energy and has poor efficiency, and attention should be paid to the power that the selected resistance can withstand.
