CLTE-AT™ Circuit Materials: Excellent Dimensional Stability High Degree of Phase Stability vs. Temperature
■CLTE-AT micro dispersed ceramic PTFE composites utilize a woven fiberglass reinforcement to provide the highest degree of dimensional stability, critical in multilayer designs. CLTE-AT laminates are in a “League of their Own” for registration when utilizing thin substrates (i.e. 0.005” and 0.010”).
■CLTE-AT laminates have “Best-in-Class” Insertion Loss (S21) and Loss Tangent (0.0013) in the commercial marketplace and second only to CLTE-XT laminates. Rogers’ CLTE-AT laminates were designed to provide a quality peel strength without having to resort to the utilization of the lossier, rougher coppers prevalent in competitive products to achieve acceptable copper adhesion.
■CLTE-AT laminates have Low CTE xyz and Very Low TCEr for applications that require Electrical Phase Stability,Dk Stability, and Mechanical Stability well over a -55 to 150°C Operating Temperature. CLTE-AT laminates continue the competitive advantages of CLTE laminates (dimensional stability, low absorption of moisture and processing chemicals, ease of processability). The higher thermal conductivity of CLTE-AT laminates improve heat transfer relative to alternative materials and enable better power handling.
