6L/8L/10L/12L LAYER SECOND ORDER PCB CIRCUIT BOARD FOR DUMMIES

Connected with the preceding level, the impedance of any signals on L4 may have smaller deviations near power rail splits on L3To use circuits on both sides, there needs to be a correct circuit relationship among The 2 sides, as shown in the images below. The “bridges amongst such circuits are named vias. A via is a small hole over the PCB b
