Kappa® 438 Laminates Data Sheet

PublishTime：2022-06-08

●Specifically formulated to have FR-4 matched dielectric constant (Dk),design transition to Kappa® 438 laminates will be effortless.These laminates also exhibit low loss,tight Dk and thickness tolerances needed to meet the growing performance needs of the wireless market traditionally served by higher end FR-4 materials.Demand for wireless data is growing exponentially,driving a need for substantially higher levels of mobile network capacity and performance.FR-4 was historically a material choice for many less demanding RF applications,but changes in the wireless infrastructure related to growing performance requirements,especially in small cells and carrier-grade Wi-Fi,has resulted in instances where the properties of FR-4 are lacking,and RF performance and consistency is compromised.
●Features and Benefits:
■Glass Reinforced Hydrocarbon Thermoset Platform
▲Ease of PCB manufacturing and assembly in line with FR-4
■Dk Tailored to FR-4 Industry Standard Norms
▲4.38 Dk for ease of transition when upgraded electrical performance is needed over FR-4
■Tighter Dk and Thickness Tolerance than FR-4
▲Consistent circuit performance
■Low Z Axis CTE and High Tg
▲Improved design flexibility,PTH reliability
▲Automated assembly compatible
■Flame Retardant Laminate
▲UL 94 V-0
