![]() Imprecise thickness: The paper doll isn’t the same thickness as the rigid and flexible sections of the PCB.While effective at modeling an approximate shape of a rigid-flex PCB, the paper doll approach has a number of inefficiencies and problems in application, including: These models, created from paper, are cut into what’s hoped to be an exact shape of the PCB in concept. The most common method deployed by design teams to ensure that a rigid-flex PCB design will fit in an enclosure is the “paper doll” model of the PCB. Among the many variables that go into the rigid-flex PCB design process, the greatest challenge faced by designers is ensuring that all flexible sections on the PCB fold in the correct way, while maintaining flex-circuit stability and product lifespan at the highest feasible degree of quality. To gain this flexibility, designers often opt for rigid-flex PCBs, which combine both the rigid and flexible substrates of a PCB into a single design element.ĭespite its numerous benefits, rigid-flex PCB design presents significant challenges in terms of effective, efficient execution. The mechanical model becoming such an influential factor has turned flexible electronics into an increasingly common design objective. The necessity to constantly satisfy the senses of the physical experience requires that printed-circuit-board (PCB) assemblies be smaller and denser to fit pre-conceptualised mechanical structures. ![]() Product experiences are being driven by customer interaction with the physical, mechanical model.
