20-layer PCB

20-layer PCB--The increase in the density of integrated circuit packaging has led to a high concentration of interconnect lines, which makes the use of multiple substrates a necessity. In the layout of the printed circuit, unforeseen design problems have appeared, such as noise, stray capacitance, and crosstalk. The following is about 20 layer Pentium Motherboard related, I hope to help you better understand 20-layer PCB.
