Rogers Introduces CLTE-MW Laminates for 5G and Other Millimeter Wave Applications


Reading time ( words)

Rogers Corporation has introduced CLTE-MW laminates, a line of ceramic filled, woven glass reinforced PTFE composites. CLTE-MW laminates were developed to provide a cost effective, high performance material for the circuit designer. This unique laminate system is well suited for applications that have limitations in thickness due to either physical or electrical constraints.

The seven available thickness options from 3 mils to 10 mils ensure that ideal signal to ground spacing exists for today’s 5G and other millimeter wave designs. In addition, a variety of copper foil options are available including rolled, reverse treated ED, and standard ED. Resistive foil and metal plate options are also available upon request.

CLTE-MW laminates are reinforced with spread glass, which along with a high filler loading help minimize the high frequency glass weave effects on electromagnetic wave propagation. Their woven glass reinforcement also provides excellent dimensional stability. Other key features of the laminate include low z-axis CTE (30ppm/°C) for excellent plated through hole reliability, a low loss tangent of 0.0015 at 10 GHz to enable low loss designs, and low moisture absorption of 0.03% to ensure stable performance in a range of operating environments.

Thermal conductivity of 0.42 W/(m.K) enables heat dissipation in aggressive designs along with a high dielectric strength of 630 V/mil to ensure good z-axis insulation between conductor layers. The UL94 V-0 flammability rating enables the use of CLTE-MW laminates in commercial applications.

CLTE-MW laminates are well suited for a range of applications including amplifiers, antennas, baluns, couplers and filters. Applicable markets range from commercial and consumer to defense and aerospace.

PCB Technologies’ InPack to Focus on Miniaturization, Packaging

05/16/2022 | Andy Shaughnessy, Design007 Magazine
I recently spoke with PCB Technologies’ Jeff De Serrano, Yaniv Maydar, and Alon Menache about their new venture, InPack. They explain their plans to focus on advanced packaging, miniaturization, and other high-end technology, with much faster time to market, and they offer a view of the global market as well.

An Inside Look at an Indian PCB Manufacturer

03/24/2022 | Dan Beaulieu, D.B. Management Group
As a student of the printed circuit board industry, I am always interested in learning more about companies all over the world. When I connected with Abhay Doshi, managing director of Fine-Line Circuits Ltd. in India, I welcomed the opportunity to learn more about him, his company, and the Indian PCB business as a whole—it was all that, and so much more. Here’s what I learned.

EIPC Technical Snapshot: A European Roundup

03/02/2022 | Pete Starkey, I-Connect007
Although it was originally proposed to hold a one-day face-to-face EIPC conference in Frankfurt, travel restrictions in Germany made this impractical. But the Technical Snapshot webinar format has proved so successful that it was decided to run an extended version as an alternative—two sessions, with three presentations each. It worked extremely well. The carefully selected program on February 23 featured excellent speakers, and seamless organisation added up to an outstanding event.
