The rise of flex and rigid-flex PCBA: OptimaTech

 

Flex and rigid-flex PCBA (printed circuit board assembly) are rapidly gaining in popularity for their ability to provide greater functionality within a smaller footprint and withstand vibration, bending and repetitive motion. From wearables to aerospace systems, manufacturers are switching from rigid boards and wiring harnesses to flexible and rigid-flex boards for ever-smaller devices and increased reliability.

You've already enjoyed the benefits of flex and rigid-flex PCBA technology if you've ever worn a smartwatch, used a wireless earbud or relied on a pacemaker to keep functioning smoothly! Silently changing the way electronics are being designed these boards and seriously, it's time some recognition.

So, What is Flex and Rigid-Flex PCBA?

Flexible printed circuit boards (flex PCBs) are manufactured on a flexible substrate that will bend, fold and flex without breaking. Rigid-flex PCBA integrates these flexible components along with conventional rigid-board pieces into a single application. Imagine the best of both worlds: A rigid board for structure where you need it, and a flex circuit for space or movement where you need it.

Rigid boards are perfect for many uses, but there are limitations to their effectiveness. They are flat, inflexible (literally), and when you need to join more than one rigid board of the type you'll need connectors, cables, or wire harnesses. Each of those additions will be one more thing that can go wrong, will be one more thing that has to be carried, and will be one more area of no space.

What has all the buzz about Flex and Rigid-Flex PCBA?

The Technology is getting Smaller (and Smarter)

Every consumer electronics company engages in a constant struggle to make their products thinner, lighter and more capable – at the same time. This is achieved with flex PCBs because they eliminate the need for connectors and cables that occupy precious internal space. A flex circuit can easily bend around corners and curved enclosures where a hard board would not fit.

When it comes to wearables, hearing aids and foldable phones, every cubic millimeter is important. Consider flex PCBA for products that must fit into a curved or space-constrained enclosure, and rigid-flex for products that require solid mounting points for connectors or heavier components, as well.

Reliability under stress is a must!

The following is something that isn't discussed enough: connectors and solder joints are easily points of failure in electronics, particularly in environments where vibration and/or movement is constant. Rigid-flex PCBA can help minimize the interconnects used in an assembly, making it easier to avoid failures.

That is why rigid-flex has become so popular in the aerospace, defense, and medical devices fields. If it is in the body or on a plane flying through turbulence at 30,000 feet, “it might work” just doesn't suffice. Reliability must be inbuilt from the beginning and rigid-flex is built for that.

The need for lighter weight but effective impact

In the aerospace and automotive industry, weight can significantly impact fuel efficiency and performance, making every gram count. Flex and flex-flex assemblies offer the added advantage of cutting weight compared to a rigid-board/harness assembly by eliminating the use of bulky connectors, additional cabling and redundant board materials.

This weight savings can mean either more flight time or more payload for drone manufacturers and satellite designers. That's a pretty interesting compromise, and one of the most obvious motivators for engineers to continue to be drawn to flexible solutions.

Design freedom that reaches to the very root of the problem

Rigid-flex PCBA allows designers to route circuits in 3D rather than 2D, as opposed to rigid or rigid-flex circuits. Looking for a board that folds down into an origami style to fit into a cylinder? Rigid-flex can do that. Looking to create an articulation between two solid parts that opens and closes with each use, such as a laptop hinge or a door hinge? With each cycle, flex circuits take that motion in stride without cracking.

This three dimensional flexibility presents completely new form factors that would not have been possible with flat boards. No longer are designers working on new solutions to old problems, they are now envisioning products that didn't exist before.

Demand is being driven by the automotive and medical industries

Whether it's sophisticated driver assistance or infotainment systems, or battery management systems in electric-powered vehicles, today's vehicles have more electronics onboard than ever before. Due to these requirements these systems must be able to endure the constant vibration, temperature changes and close packaging requirements, making flex and rigid flex PCBA a perfect match.

Likewise, flex circuits are used in medical devices ranging from diagnostic imaging to implantable devices, where biocompatibility, reliability and miniaturization are all critical. The electronic industry and the rigid-flex industry are growing at the same rate and demand for flex and rigid-flex assembly is increasing with both of these industries.

Before making a selection between flexible or rigid-flex PCBA, what factors should be taken into account?

Price is one of the primary considerations. The cost of flex and rigid-flex boards is generally more expensive initially than rigid (conventional) PCBs, as the materials used are different and the process of manufacturing is more complicated. For applications where space is not necessarily limited, cost is important, and the solution is not dynamic, opt for traditional rigid boards. If your design will require movement or need to save a lot of space, or you need to save weight for a design that you're willing to pay more for, choose the Flex or Rigid-Flex.

Another factor to consider is manufacturing complexity. Flex and Flex-Rigid Assemblies involve unique processes, tooling and expertise beyond rigid PCB manufacturing. Working with a manufacturer who is knowledgeable in flex materials, lamination processes, and controlled impedance routing can have an impact on yield and long term reliability.

Conclusion

Flex and rigid-flex PCBA is not limited to trend, but it's a revolutionary change in electronics design. With devices shrinking ever further, industries increasingly looking for reliability and applications constantly pushing the envelope of 3-D solutions, flex and rigid-flex technology will continue to play an ever more significant role.

When you're designing the next product and space, or weight, or durability are in the top of your list of concerns, you may want to consider flex or rigid-flex PCBA as a possible solution that can only be approached with a rigid board. It has been proven in some of the most challenging applications from the imagination and it can only get better from there!
