Plymouth, MA — April 6th, 2026— Tech Etch, a leading manufacturer of high-reliability flexible circuits, EMI/RFI Shielding, and precision-etched components; announces the commercial availability of its Long Flex Circuits, now production-ready in lengths up to 60 inches.
Designed to replace bulky wire harnesses in space-constrained and dynamic environments, Tech Etch's long flex circuits deliver consistent signal integrity under continuous motion, vibration, and thermal stress. These solutions are engineered to support advanced medical devices, aerospace and defense systems, robotics, and next-generation wearable technologies where performance is non-negotiable.
"Extended-length flex circuits present unique manufacturing and reliability challenges that many suppliers struggle to overcome," said Richard Cammarano, President and CEO at Tech Etch. "We've invested heavily in process control, material science, and validation to deliver long flex solutions that engineers can confidently integrate into high‑performance, reliability‑driven systems."
Tech Etch's long flex circuits are manufactured using advanced Laser Direct Imaging (LDI) and additive/subtractive copper processing to achieve fine line and space geometries over long distances. Production capabilities include trace and space down to 0.002 inch, ultra-thin 9 µm copper layers, laser-drilled microvias, and polyimide substrates optimized for flexibility and thermal stability.
The company also offers advanced construction options including adhesiveless substrates, specialty metals such as Beryllium Copper, Stainless Steel, and Tungsten, and contoured circuit designs that integrate thick contact fingers directly into flexible circuit constructions.
"These capabilities reflect our commitment to expanding what's possible with flex circuit technology," said Richard Cammarano "As medical, aerospace, and defense systems continue to demand longer reach, lighter weight, and higher reliability, Tech Etch is committed to evolving our manufacturing platform to support the next generation of products and applications."
Tech Etch currently delivers production-ready long flex circuits up to 60 inches, representing a controlled expansion of validated manufacturing capability.
As an employee-owned company, Tech Etch manufactures all long flex circuits in the United States and operates under rigorous quality and compliance standards, including ISO 13485, AS9100, ISO 9001, and ITAR registration.
