Thermoset laminate beats FR-4 performance


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.
