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.
