What is a rigid-flex PCBA board

What is a rigid-flex PCBA board? Rigid-flex printed circuit boards are circuit boards that use a combination of flex and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates that are attached externally and/or internally to one or more rigid boards, depending on the design of the application. Flexible substrates are designed to be in a constant bending state and typically form a bending curve during manufacturing or installation.
What is a rigid-flex PCBA board
Designing is more challenging than typical rigid board environments because the boards are designed in 3D space, which also provides greater space efficiency. By being able to engineer rigid-flex bonds in three dimensions, designers can twist, fold and roll flexible substrates to achieve the shape required for the final application package.

Rigid-flexible pcbA manufacturing applications:

Rigid-flex PCBA offers a wide range of applications, from smart devices to mobile phones and digital cameras. Rigid-flex manufacturing is increasingly used in medical devices, such as pacemakers, because of their space and weight reduction capabilities. The same advantages of using rigid-flex PCBs can be applied to intelligent control systems.

In consumer products, rigid-flex not only maximizes space and weight, but also greatly improves reliability, eliminating many of the need for solder joints and delicate, fragile wiring that is prone to connection problems. These are just a few examples, but rigid-flex PCBs can be used in almost all advanced electrical applications, including test equipment, tools, and automobiles.

Rigid-flex PCB technology and production process:

Whether producing rigid-flex prototypes or mass production requiring large-scale rigid-flex PCBA fabrication and PCBA assembly, the technology is well-proven and reliable. The flexible PCB section is particularly good at overcoming the space and weight issues of spatial degrees of freedom.

Careful consideration of rigid-flex solutions and proper evaluation of available options early in the rigid-flex PCB design phase will bring significant benefits. Rigid-flex PCB manufacturers must be involved early in the design process to ensure that the design and fab parts coordinate with each other and account for changes in the final product.

The manufacturing stage is also more complex and time-consuming than rigid board manufacturing. All flex components of Rigid-Flex components have a completely different processing, etching and soldering process than rigid FR4 boards.

The advantages of rigid-flex PCB

1. Space requirements can be minimized by applying 3D,

2. By eliminating the need for connectors and cables between individual rigid components, board size and overall system weight can be reduced.

3. By maximizing space, the number of parts is usually reduced.
