What Is a Flex PCB? Single-Layer vs Double-Layer Flexible Circuits for U.S. Medical Devices

Flex PCB

Quick Summary A Flex PCB is a flexible printed circuit built on polymer films (most commonly polyimide) that enables compact routing, reliable interconnects, and controlled bending in modern medical devices. In U.S. medical electronics, the most practical decision is usually between single-layer flexible circuits (thin, light, highly bend-tolerant, best for simple signals and tight packaging) […]
