Rigid-Flex Printed Circuit Boards
The use of rigid-flex PCBs in electronic devices and systems across several industries has grown. This is due to the need for compact and reliable electronics in consumer gadgets, automotive and aerospace equipment, wearable technology, as well as medical and industrial machinery. Rigid-flex PCBs are a great choice for these applications because they allow for the integration of rigid components with flexible substrates and can withstand dynamic flexing without any compromise to functionality or reliability.
Rigid-flex circuit boards offer many benefits when compared to traditional hard PCBs, including reduced manufacturing costs and extreme reliability. They are easier to design for specific spaces and can reduce the number of points of connection between rigid component areas, thereby cutting down on costs associated with connectors, wires, plug-in connections, solder joints, and more. Additionally, rigid-flex circuits can be made thinner than traditional hard PCBs, allowing them to fit in smaller and lighter products and reducing the overall weight of the device.
Because rigid-flex circuits are designed to flex during operation, they can endure continuous mechanical stress that other circuitry cannot. For example, rigid-flex printed circuit board that are used in vibration-prone environments, such as military or aerospace equipment, need to be able to withstand constant and repeated flexing. Rigid-flex PCBs can be designed to meet these requirements by incorporating features like reinforcement of the rigid sections, avoiding sharp bends, and ensuring that there is proper transition between the rigid and flex circuits to ensure that they continue functioning properly.
What Industries Use Rigid-Flex Printed Circuit Boards?
In addition, rigid-flex PCBs can be designed to handle high currents and generate heat, which makes them a great choice for applications that require high-speed data communication or power electronics. They can also withstand mechanical stress by using proper transition zones between rigid and flex circuits, distributing the load evenly and preventing structural failures. Rigid-flex circuits can also be designed with a high level of electromagnetic interference (EMI) suppression to keep consistent signal transmission and eliminate noise that may interfere with performance.
Lastly, rigid-flex circuits can be designed with hatched copper to reduce the stresses placed on flex areas by preventing contact between the rigid and flex areas. This is particularly important for dynamic flex applications that experience frequent, dynamic bending.
While flex and rigid-flex PCBs can be more expensive than traditional hard PCBs, their upfront costs can be offset by the significant savings they provide in the long run. They can save money by lowering installation and repair costs as well as minimizing downtime for industrial machinery. They can even increase profitability by reducing maintenance and replacement costs.
As new product designs require advanced flex and rigid-flex PCBs, manufacturers must be ready to make the transition. This means that they should utilize the best flex and rigid-flex PCB design software to take their prototypes through to production. Altium Designer offers a single, integrated PCB design platform that allows users to create rigid-flex and flex circuits with ease, as well as all other standard PCB types.
