The performance of PCB circuit boards depends on several key parameters, such as dielectric constant (DK value), glass transition temperature (Tg), heat resistance (Td), CTI (creep trace index), and CTE (coefficient of thermal expansion). Different board materials (such as FR4, CEM-3, and high Tg PCB) are suitable for different applications, such as high-frequency communications, automotive electronics, or high-power equipment.

The fundamental principles and advanced techniques of high-speed PCB layout design, including signal integrity management (transmission line theory, reflection control), power integrity optimization (PDN design, decoupling strategies), and electromagnetic compatibility (EMC) considerations, help achieve optimal performance in high-speed PCB design while addressing common challenges in modern electronic product development.

Innovative designs such as high-density interconnect (HDI) for IoT PCBs, micro vias, and multi-chip modules (MCM) address the challenges of miniaturization, high performance, and reliability in traditional PCBs, and propose a comprehensive optimization solution from design to manufacturing.
