Rogers Kappa 438 laminates were designed using a glass reinforced hydrocarbon ceramic system that offers superior high frequency performance and low cost circuit fabrication resulting in a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes. Kappa 438 laminates also have the UL 94 V-0 flame retardant rating and are lead free solder process compatible.
Kappa 438 laminates offer dielectric constants (Dk) tailored to FR-4 industry standard norms which facilities ease of converting existing FR-4 designs where better electrical performance is needed.
