Introduction to Kappa 438 Base Material

Rogers Kappa 438 laminates are constructed using a glass-reinforced hydrocarbon ceramic system, which delivers superior high-frequency performance and enables low-cost circuit fabrication. As a low-loss material, it can be processed using standard epoxy/glass (FR-4) manufacturing procedures. Kappa 438 laminates also possess the UL 94 V-0 flame retardant rating and are compatible with lead-free soldering processes. Standard thickness options include 10, 20, 30, 40, and 60 mil. Furthermore, Kappa 438 laminates feature dielectric constants (Dk) aligned with FR-4 industry standard norms, simplifying the conversion of existing FR-4 designs that require improved electrical performance.
