Why We need to use Multi-layer PCB Board
With the improvement of PCB technology and the increase in consumer demand for faster and more powerful products, PCB has changed from a basic two-layer circuit board to a PCB board with four, six, and up to ten to thirty layers of dielectric and conductors, this is the most important reasons Why We need to use Multi-layer PCB Board and the reverse engineering multilayer circuit board request become more and more.
Why increase the number of layers? Having more layers can increase the power distribution of the circuit board, reduce cross-talk, eliminate electromagnetic interference and support PCB board cloning with high-speed signals. The number of layers used for the PCB depends on the application, operating frequency, pin density, and signal layer requirements.
