Rogers CLTE-AT Material Introduction
Rogers CLTE-AT laminates serve as the commercial-grade solution in the CLTE™ product line, adopting core technologies from CLTE-XT™ laminates with cost-optimized modifications. This results in a dielectric constant of 3.00 and a unique thickness profile compared to CLTE-XT variants. As micro-dispersed ceramic PTFE composites, CLTE-AT laminates integrate woven fiberglass reinforcement to achieve outstanding dimensional stability—a critical attribute for complex assemblies, particularly with thin substrates (0.005” and 0.010”).
CLTE-AT laminates deliver best-in-class insertion loss (S21) and a low loss tangent (0.0013) in the commercial market, second only to CLTE-XT. They achieve superior peel strength without relying on the lossier, rougher copper surfaces used in competing products. Furthermore, CLTE-AT features low CTE across XYZ axes and extremely low TCEr, ensuring electrical phase stability, Dk stability, and mechanical stability over an operating temperature range of -55°C to 150°C. It retains the competitive advantages of CLTE laminates, including minimal moisture and process chemical absorption, ease of processability, and enhanced thermal conductivity for improved heat transfer and power handling capabilities.
