Nortech Systems Announces Patent for Flexible Faraday Cage PCB and Cable


Reading time ( words)

Nortech Systems Incorporated, a leading provider of engineering and manufacturing solutions for complex electromedical and electromechanical products serving the medical, industrial and defense markets, announced this week that the US Patent Office has issued Patent No. 11,412,608, for the Company’s Flex Faraday Xtreme™, a flexible printed circuit for transmitting high-frequency signals while precisely controlling both crosstalk and impedance, minimizing electromagnetic interference, improving parallel transmission alignment, and increasing data density. This work is based on the important work of Michael Faraday in the 1830s that contributed to our current understanding of shielding effects of what we now call a Faraday Cage.

“Nortech’s commitment to innovative technologies is key to supporting our strategic medical, industrial, and defense customers,” said Jay D. Miller, Chief Executive Officer and President. “In highly complex and compact devices, the FFX is designed to provide the signal integrity necessary to support sensitive, mission-critical applications.” 

“With our patent of the Flex Faraday Xtreme (FFX), Nortech provides intelligent transmission lines that provide benefits over traditional micro coax cables in challenging applications,” said Steve Czeck, Senior Director of Engineering. “FFX technology will be applied to meet customer requirements for size or weight constraints, or where harsh conditions exist.”

Both FFX and the recent Active Optical Xtreme™ product launch are early steps in the Company’s long-term pivot toward serving strategic customers by building higher level assemblies that contain advanced technologies and solve difficult connectivity challenges. Invented by Scott Blanc, Principal Engineer, FFX is the Company’s first patent in its technology portfolio. FFX adoption will ramp up through 2023 and will not have a material impact on Nortech's 2022 or 2023 financial results.

Part 2: The Printed Electronics Roundtable

09/22/2022 | Andy Shaughnessy, Design007 Magazine
We recently held a roundtable with a team of printed electronic circuit experts from companies that run the gamut: John Lee and Kevin Miller of Insulectro, Mike Wagner of Butler Technologies, Tom Bianchi of Eastprint, and John Voultos of Sheldahl Flexible Technologies. In the first part of this roundtable, the team dispelled a variety of myths surrounding PEC. In this second part of the roundtable, the participants discuss what designers and fabricators need to know to jump into printed electronics, and some of the drivers behind this growing technology.
