As the miniaturization trend in electronics continues, rigid-flex PCBs grow in popularity. This is because they require up to 60 percent less space than standard PCBs.
Rigid-flex PCBs feature rigid and flexible circuit substrates that are laminated together, but allow for components to be mounted on both sides. Equally important, their integrated circuits electrically connect the system together, eliminating the need for connectors or connecting cables between the sections.
