RO4835 high-frequency laminate is formulated for improved oxidation resistance. Dielectric constant is 3.48 and low loss tangent is 0.0037 at 10GHz. Z-axis coefficient of thermal expansion (CTE) is low for plated-through-hole (PTH) reliability under a variety of processing and operating conditions. Exhibits x- and y-axis expansion coefficients similar to that of copper, for dimensional stability. Is RoHS-compliant, and requires no special preparation, and can be processed using standard methods.
