Rogers to Showcase Advanced Circuit Materials at the Del Mar Electronic & Manufacturing Show
April 23, 2018 | Rogers CorporationEstimated reading time: 3 minutes
Rogers Corporation will be highlighting circuit materials with the characteristics needed for present and future high-frequency electronic circuit designs, including Fifth Generation (5G) wireless networks, at the upcoming Del Mar Electronic & Manufacturing Show, May 2-3 at the Del Mar Fairgrounds (San Diego, California). The Del Mar Electronic & Manufacturing Show is a premiere event for designers and manufacturers of consumer electronic products and services as well as technology-based products.
Representatives from Rogers Corp. (www.rogerscorp.com) will be at Booth #622 to offer advice and guidance on the optimum use of their circuit materials for many present and future high-frequency circuit designs, including RO4835T™ laminates, RO4450T™ Bonding Materials and CU4000™ and U4000 LoPro® copper foils for forming thin, low-loss multilayer circuits, CLTE-MW™ laminates for microwave and millimeter-wave circuits in present and future communications devices, and RO4360G2™ laminates for compact, low-cost power amplifiers in wireless base stations.
Visitors to the Rogers booth at the Del Mar conference and exhibition can learn more about low-loss materials for multilayer circuits, such as RO4835T laminates and RO4450T bonding materials. With the growing demand for complex high-frequency and high-speed circuits that must fit tight places, multilayer circuit constructions provide solutions in compact sizes. RO4835T laminates are low-loss, spread-glass-reinforced, ceramic-filled thermoset materials that serve as thin, high-performance inner circuit layers when used with Rogers Corp.’s RO4835 laminate, the RO4000® family of laminates, or with CU4000 or CU4000 LoPro foils when designers are looking for foil lamination builds.
RO4835T laminates, which are available in 2.5, 3, and 4 mil thicknesses, feature stable dielectric constant (Dk) of 3.3. When fabricating thin multilayer circuits, Rogers Corp.’s RO4450T Bonding Materials provide 3.2 to 3.3 Dk and low-loss characteristics to complement RO4835T, RO4835, and RO4000 laminates in forming reliable multilayer circuits compatible with FR-4 processing methods. Spread-glass-reinforced, ceramic-filled RO4450T bonding materials are available in 3, 4, and 5 mil thicknesses and, along with RO4835T laminates, are lead-free process compatible and feature the UL 94 V-0 flame-retardant rating.
For emerging Fifth Generation (5G) wireless networks and their use of added bandwidth at millimeter-wave frequencies of 24 GHz and higher, CLTE-MW laminates are available in seven thickness options from 3 to 10 mils for circuit designs limited in thickness due to mechanical or electrical requirements, including for PCB antenna arrays. These are ceramic-filled, woven-glass-reinforced PTFE composite materials with excellent dimensional stability and low Z-axis (thickness) coefficient of thermal expansion (CTE) of 30 ppm/ºC for reliable plated through holes.
Cost-effective CLTE-MW laminates have high filler loading to minimize glass-weave effects that can be detrimental at millimeter-wave frequencies. They feature low loss tangent of 0.0015 at 10 GHz, low moisture absorption of 0.03%, and thermal conductivity of 0.42 W/mK for effective dissipation of heat in high-power circuits. CLTE-MW laminates are available with a number of copper foil options, including rolled, reverse-treated ED, and standard ED copper. Resistive foil and metal plate options are also available upon request. These thin, high-frequency laminates also feature the UL 94 V-0 flame-retardant rating.
Rogers will have other materials on display at Del Mar Booth #622, including RO4360G2 laminates, formulated for power amplifier designers seeking enhanced thermal reliability in smaller circuit sizes. These low-loss glass-reinforced, ceramic-filled thermoset circuit materials process similar to FR-4 with low dissipation factor of 0.0038 and thermal conductivity of 0.75 W/mK well suited for power amplifier designs. RO4360G2 laminates exhibit a dielectric constant of 6.15 at 10 GHz in the z direction, tightly controlled within +/-0.15. These are just a sampling of the materials that will be on display at the Rogers booth at the upcoming Del Mar Electronic & Manufacturing Show.

Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs
09/08/2025 | Kurt Palmer -- Column: Driving InnovationIn PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.
Trouble in Your Tank: Minimizing Small-via Defects for High-reliability PCBs
08/27/2025 | Michael Carano -- Column: Trouble in Your TankTo quote the comedian Stephen Wright, “If at first you don’t succeed, then skydiving is not for you.” That can be the battle cry when you find that only small-diameter vias are exhibiting voids. Why are small holes more prone to voids than larger vias when processed through electroless copper? There are several reasons.
The Government Circuit: Navigating New Trade Headwinds and New Partnerships
08/25/2025 | Chris Mitchell -- Column: The Government CircuitAs global trade winds continue to howl, the electronics manufacturing industry finds itself at a critical juncture. After months of warnings, the U.S. Government has implemented a broad array of tariff increases, with fresh duties hitting copper-based products, semiconductors, and imports from many nations. On the positive side, tentative trade agreements with Europe, China, Japan, and other nations are providing at least some clarity and counterbalance.
How Good Design Enables Sustainable PCBs
08/21/2025 | Gerry Partida, Summit InterconnectSustainability has become a key focus for PCB companies seeking to reduce waste, conserve energy, and optimize resources. While many discussions on sustainability center around materials or energy-efficient processes, PCB design is an often overlooked factor that lies at the heart of manufacturing. Good design practices, especially those based on established IPC standards, play a central role in enabling sustainable PCB production. By ensuring designs are manufacturable and reliable, engineers can significantly reduce the environmental impact of their products.
