WL-CT338 High Frequency PCB
Introduction
WL-CT series laminates are high-frequency materials that combine hydrocarbon resin, ceramic, and glass fiber cloth in a thermosetting resin system, providing low loss performance and meeting high-frequency design requirements. The combination of hydrocarbon resin and composite ceramics in this series results in low loss, high temperature resistance, temperature stability, stable dielectric constant, low thermal expansion coefficient, and a high TG value exceeding 280℃.
Features
The dielectric constants of these series range from 3.0 to 6.15, with a dissipation factor ranging from 0.003 to 0.005. For instance, WL-CT338 exhibits a DK value of 3.38 and a DF value of 0.0029.
These materials feature a combination of forward rotating ED copper and reverse treated foil (TRF) cladding. The standard options for copper weight include 0.5oz and 1oz, with the possibility of customizing other heavier weights.
TRF copper foil is adhesive-backed, resulting in a 7 mil thicker than that of ED copper substrate. The peel strength for these series is 0.72 N/mm.
The coefficient of thermal expansion (CTE) in the X/Y direction is matched to copper foil, ranging from 11 to 18 ppm/℃. In the Z direction, minimal expansion is observed, ranging from 31 to 50 ppm/℃.
These materials exhibit favorable water absorption rates, ranging from 0.02% to 0.15%. Additionally, they offer high thermal conductivity, ranging from 0.41 to 0.72 W/mK.
