Kappa 438 glass-reinforced, hydrocarbon thermoset laminates from Rogers serve as a more reliable alternative to FR-4 laminates in wireless circuit designs, especially in small cells and carrier-grade WiFi/LAA (Licensed Assisted Access). According to the manufacturer, Kappa 438 offers the performance of mid-tier circuit materials that extend beyond the performance limitations of FR-4, providing an optimum blend of price, performance, and durability.

These laminates exhibit low loss, as well as tight dielectric-constant tolerance and tight thickness tolerance. A dielectric constant of 4.38 is tailored to FR-4 industry-standard norms to ease the conversion process of existing FR-4 designs. Kappa 438 laminates are compatible with conventional bond plies and lead-free solder processes. They also carry a UL 94V-0 flame-retardant rating.
