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.

Electroplating types (ENIG, Sn/Pb, OSP, etc.), their application scenarios, and comparative advantages. Solutions to eight common electroplating defects (such as uneven thickness, discoloration, etc.) through equipment optimization, process parameter adjustments, and improvements to pre- and post-treatment methods.
