Rogers Launches Laminates for Automotive Radar Sensor Applications
December 12, 2016 | Rogers CorporationEstimated reading time: 1 minute
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.

The Chemical Connection: Surface Finishes for PCBs
03/31/2025 | Don Ball -- Column: The Chemical ConnectionWriting about surface finishes brings a feeling of nostalgia. You see, one of my first jobs in the industry was providing technical support for surface cleaning processes and finishes to enhance dry film adhesion to copper surfaces. I’d like to take this opportunity to revisit the basics, indulge in my nostalgia, and perhaps provide some insight into why we do things the way we do them in the here and now.
