CLTE-AT™ laminates represent the commercial version of the CLTE™ product line. CLTE-AT laminates use the common building blocks developed with CLTE-XT™ laminates, but with some changes to make the product more affordable. This results in a higher dielectric constant (3.00) and a slightly different thickness than the CLTE-XT laminates.


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 are 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℃ 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 improves heat transfer relative to alternative materials and enables better power handling.
