Complete Guide to High-Frequency PCB Laminate Selection and Brands
I. Decoding the “Physical Language” Behind MaterialsThe core of high-frequency laminate performance lies in understanding the interaction between electromagnetic waves and materials. Mastering these three parameters is essential: The stability of the Dielectric Constant (Dk) is far more critical than its nominal value. Many beginners focus only on room-temperature Dk but overlook the Temperature Coefficient (TCDk). In […]
