The coefficient of thermal expansion (CTE), known as the "invisible killer" in high-frequency PCB design, is crucial for printed circuit boards. High-frequency PCBs are vital for electronic devices requiring high signal transmission quality, as the CTE measures how much a material's volume or length changes with temperature fluctuations, directly affecting circuit performance and reliability. |
