Printed circuit board (PCB) laminates are critical materials used as the base for constructing PCBs, providing mechanical support and electrical insulation. Datasheets for PCB laminates typically include key parameters like thermal conductivity, dielectric constant, glass transition temperature (Tg), and flame retardancy ratings. These specifications help designers select the appropriate material for specific applications, ensuring reliability and performance in environments with varying thermal, electrical, and mechanical demands. Understanding these properties is essential for optimizing PCB design and manufacturing processes.
