What Are The Difficulties in The Production of High-Level PCB Circuit Boards?
High-level PCBs are usually defined as 10-20 layers or more high-level multi-layer circuit boards. Compared with traditional PCB products, high-level PCBs have the characteristics of multiple thicknesses, multiple layers, dense lines, multiple through holes, large cell sizes, and thin dielectric layers, and require internal space, layer alignment, impedance control, and reliability. High; mainly used in…
