Delve into the expertise of PCB layer selection, from basic single-layer boards to complex 16-layer and above PCBs, analyzing the advantages and disadvantages, cost considerations, and typical application scenarios of each. Make informed decisions that balance performance and cost.

PCB impedance control is a core technology in high-speed circuit design, directly affecting signal integrity and system performance. How to achieve perfect impedance matching through precise material selection, layer stack design, line width calculation, and process control to safeguard your electronic design.

The cost structure of PCB circuit boards, the impact of increased layer counts, material selection, and special processes on costs. By establishing a comprehensive cost model, an optimization strategy based on Six Sigma design was proposed, and industry cost trends were predicted.
