CEM-1 and CEM-3 are composite PCB materials commonly used as alternatives to FR4 in cost-sensitive applications. Understanding their differences helps designers and buyers choose the most suitable substrate for specific products.
Low-loss PCB materials are used in RF and microwave circuits to reduce signal attenuation at high frequencies. Compared with FR4, these materials provide lower dielectric loss and more stable electrical behavior. This article explains the common low-loss materials and how to choose them based on frequency, performance, and cost.
