Record breaking length of a single trace in a flexible circuit. Qflex completed with exotic project. It was a security enclosure with a single trace in serpentine pattern covering 2 layers. It was a 8 mil trace, 60,000 inch long.
The flex was mounted in a metal lid that formed the front part of a security cabinet with highly sensitive electronics. If any attempt is made to drill a hole and insert monitoring probe, the trace would break and alarm would be triggered.
The project was completed successfully and installation was secured using this technology.
