Rigid-flex PCB fabrication is a specialized process that combines the advantages of both rigid and flexible printed circuit boards (PCBs) into a single, integrated design. This intricate manufacturing method involves creating multiple layers of rigid and flexible substrates, which are then laminated together. Rigid-flex PCBs offer exceptional versatility, as they can be folded, bent, or twisted to fit complex form factors and tight spaces. This makes them ideal for applications where durability and space-saving are crucial, such as aerospace, medical devices, and consumer electronics. Rigid-flex PCB fabrication requires precision engineering and strict quality control to ensure reliable and durable performance in diverse environments.
