Rigid Flex PCBs

Rigid flex PCBs are a great choice for ultra-thin packaging needs. As its name suggests, rigid flex printed circuit boards are hybrid boards which integrate elements from both hardboards and flexible circuits. The key advantage is that they can be folded or flexed while maintaining shape. While the rigid PCBs are responsible for holding all the components, the flexible film connects two rigid PCBs. It is possible to create these custom boards depending on whether you want the outward or inward layers to be flexible. With their ability to streamline the electronic design, they provide added functionality and improved electrical performance.

As a well-known Rigid Flex PCB manufacturer, we have covered all your rigid flex PCB needs. Count on us to create custom rigid flex boards as per your bespoke specifications that suit the requirements of your application.

Benefits of Rigid Flex PCBs

There are a wide variety of advantages some of them include:

  • Improved connection reliability on account of fewer solder joints.
  • Reduced weight and space requirements.
  • Rigid Flex printed circuit boards are suitable for high-shock and high-vibration environments without causing equipment failure and hence known for reliability.
  • Suited for high-density applications. Little surprise then that as the trend of miniaturization grows, their use become ubiquitous.
  • Overall, they lend themselves to optimized costs as their advantages far outweigh the increase in costs.
  • Rigid flex PCBs are known for their ease of assembly.

The rigid flex PCBs are hybrid boards which integrate elements from both hardboard and flexible circuits. It offers a wide variety of advantages including improved reliability and reduced weight.

Mainly, rigid flex printed circuit boards are categorized in three types including single sided rigid-flex PCBs, double sided rigid-flex PCBs, and multi-layer rigid-flex PCBs.

Rigid PCBs are stiff and unbendable and thereby largely not flexible. Flexible PCBs, on the other hand, can fit a designated system on account of their ability to flex. Rigid flex PCBs are a hybrid design of rigid and flexible boards, which ensure they are sturdy and supportive in some areas and flexible in others.

Absolutely! From 2-24 layers, you could take your pick!

Rigid flex PCB manufacturing process involves multiple steps including preparing the base material, circuit pattern generation, Cover lay, cutting out the flex, electrical testing & verification.

The Rigid printed circuit boards consist of bare boards with FR-4 glass epoxy panels. The rigid PCBs are designed in single or multiple layers.

Normally the lead times for such boards is 1-2 weeks, however it will depend on the bespoke requirements.

We manufacture rigid flex circuit boards, rigid PCBs and flex PCBs in accordance with UL, ISO-9001, AS 9100, IPC-6012/6013 and MIL performance standards.
