MINNEAPOLIS—A flexible printed circuit for transmitting high frequency signals earned Nortech Systems Incorporated a patent from the U.S. Patent Office, the company said in a release.

The Patent Office issued the patent (No. 11,412,608) to Nortech for its Flex Faraday Xtreme™ (FFX), described by the company as a flexible Faraday Cage printed circuit board and cable. The flexible circuit is reported to precisely control crosstalk and impedance while minimizing electromagnetic interference, improving parallel transmission alignment, and increasing data density.

Nortech’s work is based on Michael Faraday’s efforts in the 1830s that contributed to the current understanding of shielding effects of what is now known as a Faraday Cage, the company said in the release.

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

Nortech Systems said it provides design and manufacturing services for complex electromedical devices, electromechanical systems, assemblies, and components. The company serves primarily the medical, aerospace and defense, and industrial markets.

“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, Nortech’s senior director of engineering, in the release. “FFX technology will be applied to meet customer requirements for size or weight constraints, or where harsh conditions exist.”

Invented by Scott Blanc, principal engineer at Nortech, FFX is the company’s first patent in its technology portfolio. Adoption of FFX will ramp up through 2023, the company said.

Both FFX and Nortech’s 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,” according to the release.

Nortech’s design services span concept development to commercial design, and include medical device, software, electrical, mechanical, and biomedical engineering. The company said its manufacturing and supply chain capabilities are vertically integrated around wire, cable, and interconnect assemblies, printed circuit board assemblies, and system-level assembly, integration, and final test.
