Rogers to showcase high-performance circuit materials
Members of Rogers ACMD will be on hand at Booth #2515 to discuss the benefits and advantages of their printed-circuit-board (PCB) materials in high-frequency analog and high-speed digital circuits. For designers of high-power, high-frequency circuits, such as power amplifiers and beam-forming networks, RT/duroid 6035HTC features outstanding thermal conductivity of 1.44 W/m-K with z-axis dielectric constant of 3.5 and low loss tangent of 0.0013 at 10 GHz. RT/duroid 6035HTC laminates consist of a high-thermal-conductivity (HTC) fluoropolymer composite with thermally stable, reverse-treated and electrodeposited copper foil and a unique filler material that helps minimize wear on machine tools compared to competitors’ high thermal conductivity substrates that use abrasive fillers.
The cost-effective RO4360 laminates are also characterized by FR-4-like processing ease, but with a tailored dielectric constant of 6.15 at 10 GHz. RO4360 materials are glass-reinforced thermoset materials with a low dissipation factor of 0.0038 at 10 GHz. The high dielectric constant allows designers of high-frequency circuits, such as antennas and amplifiers, to create miniature designs compared to circuit-board materials with lower dielectric-constant values. RO4360 laminates have a low coefficient of thermal expansion (CTE) of 30 ppm/°C for reliable plated through holes (PTH) and an excellent thermal conductivity value of 0.8 W/m-K,
Visitors to Rogers’ booth will also have a chance to learn about the Advanced Circuit Materials Division’s Technology Support Hub. It is an efficiently organized information center within the Rogers website (www.rogerscorp.com/acm/technology) that offers a free download of Rogers’ Microwave Impedance Calculator software for calculating transmission-line impedance values on different materials as well as an operator’s manual for the software. The Technology Support Hub also provides a wealth of articles based on the use of Rogers’ materials, technical reports, and design tips, as well as a quick link to an engineer when technical assistance is needed. Visitors to Rogers’ booth will have access to a personal computer and can register as a user of the Technology Support Hub, for free access to its many benefits.
