Rogers Corporation announced the latest addition to its
RO4000® Series thermoset circuit materials: RO4830 high-frequency laminates.
RO4830 laminates offer 76-to-81-GHz auto radar sensor designers a lower-cost-but-performance-competitive
option. Rogers RO4830 laminates have a lower price point and are processed by
means of standard epoxy/glass (FR-4) circuit fabrication methods, for lower
overall production costs versus PTFE-based circuits.
Available in dielectric thicknesses of 0.005 and 0.0094
inch, RO4830 laminates are suited for cap layers on FR-4 multi-layer PCB
designs. The optimized resin, glass and filler content of RO4830
laminates translates to a relative dielectric constant (Dk) of 3.2 at 77 GHz,
close to matching that of the PTFE-based circuit materials typically used for
millimeter-wave circuits. At 76-to-81-GHz, thin laminate insertion loss
is heavily influenced by copper foil roughness, and therefore RO4830 laminates
are clad with Rogers LoPro® reverse-treated copper foil to achieve very low
insertion loss of 2.2 dB/inch for 5 mil laminates, as measured by the
microstrip differential phase length method.
Spread glass and a filler with a smaller and more uniform
particle size distribution contribute to consistent within sheet dielectric
constant as well as good laser drilling performance. The RO4830 laminates
are based on the same anti-oxidant formula used in Rogers RO4835™ laminates and
are more resistant to oxidation than other hydrocarbon-based laminates.
Rogers RO4830 high frequency thermoset laminates are
available in standard panel sizes of 12 × 18 in. (305 × 457 mm), 24 × 18 in.
(610 × 457 mm), and 48 × 36 in. (1220 × 914 mm) with 0.5 oz. (18 μm) or 1.0 oz
(35 μm) reverse-treated EDC foil.
