Rogers Launches Laminates for Automotive Radar Sensor Applications


Reading time ( words)

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.

EIPC Technical Snapshot: Supply Chain and Material Price Pressures

04/26/2021 | Pete Starkey, I-Connect007
EIPC’s seventh Technical Snapshot webinar on April 14 was timely and appropriate. In the context of current supply chain issues and material price pressures facing the PCB industry, particularly in Europe, the EIPC team brought together an outstanding group of experts—each a leading authority in his field—to analyse and comment upon the areas of concern and to respond to questions raised by a capacity audience. As Alun Morgan said, “If you don’t use the European supply chain, you won’t have it anymore!”

Time, Space, Structure, and Model Analysis of CCL Price Increase

04/19/2021 | Hu Yang, Zhongtai Securities Research Center
According to the CCL Association, copper foil accounts for the largest proportion of raw materials (traditional CCL uses epoxy resin, glass fiber cloth and copper as raw materials). Copper foil in thin plate accounts for about 30% of the overall cost; in thick plate copper accounts for 50%. In CCL production, using Shengyi Technology and Chaohua Technology as examples, the cost of raw materials accounts for about 88% of the total cost, with labor accounting for about 4%. Other costs such as equipment depreciation account for about 8%.

Top Five Takeaways from IPC APEX EXPO 2021

04/15/2021 | Chris Mitchell, IPC VP, Global Government Relations
IPC APEX EXPO 2021, which went all virtual this year, exemplified how the electronics industry has responded to the COVID-19 global pandemic: with resiliency, agility, and an unwavering commitment to build electronics better. APEX EXPO featured great content and robust discussions on topics of critical importance to the global electronics industry. From my vantage point leading IPC’s government relations programs, here are my top five takeaways from this year’s event.
