What is Rigid flex PCB

The trend to miniaturization in electronics continues. Integrated circuit board solutions are becoming more and more popular as a means of efficiently utilizing the even smaller casing volume in all three dimensions.

A rigid-flex printed circuit board is unique as the rigid part of the circuitry can be placed directly into the application. Then, the flexible section can be bent and even folded to fit around components to make another direct connection. This aspect ensures a reliable connection to parts for higher performance.

Some of the most common products that incorporate rigid-flex PCBs in their design include laptop computers, smartphones, and wearable devices due to the bending capabilities of rigid-flex.

Rigid-flex pcb boards are PCBs that have Flexible PCBs (FPC) and Rigid PCBs on the same board, which are commonly employed to save space, remove wiring assemblies and can also be welded with complex components. Combining other higher technology boards, such as HDI, as a part of its packaging, is also a common design.

Benefits of Rigid Flex PCB

  • Space requirements can be minimized by applying 3D
  • By removing the need for connectors and cables between the individual rigid parts the board size and overall system weight can be reduced.
  • By maximizing space, there is often a lower count in parts.
  • Less solder joints assure higher connection reliability.
  • Handling during assembly is easier in comparison with flexible boards.
  • Simplified PCB assembly processes.
  • Integrated ZIF contacts provide simple modular interfaces to the system environment.
  • Test conditions are simplified. A complete test prior to installation becomes possible.
  • Logistical and assembly costs are significantly reduced with flex-rigid boards.
  • It is possible to increase the complexity of mechanical designs, which also improves the degree of freedom for optimized housing solutions.

Rigid Flex PCB Fabrication Applications

Rigid flexible PCBs offer a wide array of applications, ranging from military weaponry and aerospace systems to cell phones and digital cameras. Increasingly, rigid flex board fabrication has been used in medical devices such as pacemakers for their space and weight reduction capabilities. The same advantages for rigid flex PCB usage can be applied to military weaponry and weapon control systems

In consumer products, rigid flex doesn't just maximize space and weight but greatly improves reliability, eliminating many needs for solder joints and delicate, fragile wiring that are prone to connection issues. These are just some examples, but rigid flex PCBs can be used to benefit nearly all advanced electrical applications including testing equipment, tools and automobiles.

Available structures for rigid flex PCB

There are numerous, different structures available. The more common ones are defined below:

  • Traditional rigid flex construction (IPC-6013 type 4) Multilayer rigid and flexible circuit combination containing three or more layers with plated through holes.
  • Asymmetrical rigid flex construction, where the FPC is situated on the outer layer of the rigid construction. Containing three or more layers with plated through holes.
  • Multilayer rigid flex construction with buried / blind via (microvia) as part of the rigid construction. 2 layers of microvia are achievable. Construction may also include two rigid structures as part of a homogeneous build.

State of the art interconnection technologies like stacked or staggered vias and via-in-pad structures are used to drive miniaturization further down the road. A big portfolio of surface finishings is enabling Hemeixin customers to use all available assembly methods on boards produced by us.

Rigid flexible PCB circuits are an essential part of modern day technologies. The fact that they can bend and be folded means that these circuits are highly adaptable to any circumstance and application. One simply does not have that capability when it comes to completely rigid circuits, which serve their purpose in conventional electronics, but fail when it comes to specialized situations.

There are many advantages to using rigid flex PCB over traditional circuit boards. For example, during the manufacturing process, conventional boards are exposed to potential human error when soldering, routing, or wrapping the wires. But because rigid flex circuits must be manufactured through automated processes adhering to precise designs, there is less room for error.

Of course, the greatest advantage to using rigid flex circuits is that they are designed to have the freedom to move without compromising the overall integrity of the device’s components over time.

Our rigid flex PCB manufacturing allows circuits to be configured in ways that satisfy your specifications and needs. We can create circuit boards according to specific shapes, and we can also modify their thickness. That means that the circuit board’s flexibility doesn’t just extend to its physical properties, but also in the various ways it can be designed. Rather than creating a product around your circuit board, we allow you to build your rigid flex PCB around your product, ultimately reducing size and space limitation issues and considerations.

Moreover, when talking about the functionality of rigid flex PCB manufacturing it is also important to consider the higher device density population it enables, allowing for more features to be included in your product.

Finally, since the rigid flex PCB circuits are thinner and less bulky than conventional circuit boards, heat is able to dissipate with a higher degree of effectiveness, resulting in a longer operational duration.

The bottom line is that rigid flex PCB is the right choice for you if you want to produce lighter, functional products.
