Rogers Corporation will be at PCB West, one of the electronic industry’s major technical events, on September 16, 2015 at the Santa Clara Convention Center (Santa Clara, CA). Rogers will provide examples of its high-performance printed-circuit-board (PCB) materials and participate in the technical symposium with a talk on how to perform wideband testing of PCBs with plated finishes.
Rogers’ personnel will be at Booth 200 with examples of high-frequency circuit materials, including Rogers RO4835™, RO4360G2™ and RO3003™ high performance laminates.
Rogers RO4835 high-frequency laminates, specially formulated with enhanced oxidation resistance, were developed for applications needing improved electrical stability over time and temperature, while maintaining the cost advantages of a thermoset, FR-4 processable material. Just as with RO4350B™ material, RO4835 laminates offer a dielectric constant of 3.48 at 10 GHz, a low loss tangent of 0.0037 at 10 GHz, and low z-axis coefficient of thermal expansion (CTE) for excellent plated-through-hole (PTH) reliability across a wide range of processing and operating conditions.
These improved oxidation resistant circuit materials exhibit x- and y-axis expansion coefficients similar to that of copper. RO4835 laminates are RoHS-compliant, do not require special preparation, and can be processed using standard fabrication methods. Typical applications include automotive radar and sensors, point-to-point microwave backhaul units, power amplifiers and phased-array radar.
For designers seeking further circuit miniaturization, Rogers will also be showing its RO4360G2 circuit laminates. These circuit materials have a tailored high Dk of 6.15 @ 10 GHz, which allows next generation power amplifier designers to meet size and cost reduction targets. Specifically, the laminates’ higher Dk allows for a significant reduction in finished circuit board size (approximately 25-30% in most cases). RO4360G2 laminates process similar to FR-4, are automated assembly compatible, and offer the same reliability and repeatability that customers have come to expect from Rogers RO4350B material.
With a UL 94V-0 flame rating and fully lead-free process capable, RO4360G2 laminates possess excellent thermal conductivity of .81 W/m/K for improved reliability, a low Z-axis CTE for reliable plated through holes, and drill performance as good as or better than RO4350B material.
RO3003 laminates have tightly controlled dielectric constant (3.04+/-0.04 at 10GHz) and very stable dielectric constant performance over temperature (-3 ppm/°C from -50°C to 150°C). The RO3003 PTFE-ceramic composite resin system enables very low dielectric loss (0.0010 at 10GHZ), and laminates can be purchased with rolled copper to further enhance PCB insertion loss performance. Due to its excellent electrical properties, RO3003 laminates are often chosen for millimeter wave applications such as 77-79GHz automotive radar sensors and 60GHz point to point backhaul applications.
As part of the PCB West 2015 technical conference, Rogers’ Technical Marketing Manager John Coonrod, author of the popular ROG Blog series, will be presenting “Wideband Insertion Loss Testing of Multiple PCB Final Plated Finishes”. Admission to the presentation, which is part of session F1 scheduled for September 16, 9:00 –10:00 AM, is free of charge for all exhibition and conference attendees.
