What is rigid flex PCB?

Rigid-Flex design is more challenging than typical rigid board environment design, because these boards are designed in 3D space, which also provides higher space efficiency. By being able to design in three dimensions, rigid flexible designers can twist, fold and roll the flexible board substrate to achieve the shape required for the final application packaging.
Manufacturing application of Rigid-Flex Board
Rigid-Flex Board provides a wide range of applications, from military weapons and aerospace systems to mobile phones and digital cameras. More and more Rigid-Flex Board manufacturing has been used in medical devices such as pacemakers because of their space and weight reduction capabilities. The same advantages used by Rigid-Flex Board can be applied to military weapons and weapon control systems.
In consumer products, Rigid-Flex Board can not only maximize space and weight, but also greatly improve reliability, eliminating many requirements for solder joints and fragile and fragile wiring that is prone to connection problems. These are just a few examples, but R igid-Flex PCBs can be used in almost all advanced electrical applications, including test equipment, tools, and automobiles.
Rigid-Flex Board technology and production process
Whether it is the production of rigid flexible prototypes or the need for large-scale R igid-flex PCB manufacturing and PCB Mixed Assembly mass production, this technology has been fully verified and reliable. The flexible PCB part is particularly good at overcoming the space and weight problems of space freedom.
Careful consideration of the R igid-Flex solution and proper evaluation of the available options in the early stages of the rigid flexible PCB design phase will bring significant benefits. It is vital that R igid-Flex PCB manufacturers are involved in the early stages of the design process to ensure that the design and manufacturing are coordinated and to resolve changes in the final product.
Rigid-Flex manufacturing stage is also more complicated and time-consuming than rigid board manufacturing. All flexible components of R igid-Flex components have completely different processing, etching and welding processes from rigid FR4 boards.
The benefits of Rigid -Fl ex PCB s
· Minimize space requirements by applying 3D
· By eliminating the need for Cable Connectors I/O Connectors between rigid components, the size of the circuit board and the weight of the entire system can be reduced.
· By maximizing space, the number of Surface-Mount (SMT) &BGA Assembly parts is usually small.
· Reduce solder joints to ensure higher connection reliability.
· Compared with the flexible board, the operation during the assembly process is easier.
· Simplified PCB assembly process.
· The integrated ZIF contact provides a simple modular interface for the system environment.
· Simplified test conditions. A complete test before installation becomes possible.
· Using R igid-Flex board can significantly reduce logistics and assembly costs.
· The complexity of the mechanical design can be increased, which also increases the freedom of optimizing the housing solution.
Rigid -Fl ex Des ign and Fabrication Issues
In the R igid-Flex PCB design process, certain considerations of the final product size change must be considered. In the manufacture of the Rigid-Flex board, once the bonded copper foil is etched away, the flexible polyimide core will shrink. This change must be considered in the design process.
