Highfive Rigid Flex Capabilities

Rigid Flex Capabilities can match your Prototypes and NPI, Pilot, Mix-production Based on Cheap Cost

Rigid flex capabilities are boards using a combination of flexible and rigid boards with technologies.

Most rigid-flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally.

Depending upon the design of the application.

The flexible substrates are designed to be in a constant state of flex and are usually formed into the flexed curve during manufacturing or installation.

Rigid Flex capabilities and designs are more challenging than the designs of those typical rigid board applications, as the rigid-flex boards are designed in a 3D space.

Which also with greater spatial efficiency.

By being able to design in three dimensions rigid flex designers can twist, fold, and roll the flexible board to achieve their desired shape for the final application’s package.

Rigid Flex Capabilities Applications

Rigid-Flex PCBs offer a wide array of applications, ranging from smart devices 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 smart 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 Rigid flex capabilities can be used to benefit nearly all advanced electrical applications

including testing equipment, tools, and automobiles.

Rigid Flex Capabilities and Production Process

Whether producing a rigid flex prototype or production quantities requiring large scale Rigid-Flex PCBs fabrication and PCB assembly.

The technology is well proven and reliable. The flex PCB portion is particularly good in overcoming space and weight issues with spatial degrees of freedom.

Careful consideration of Rigid-Flex solutions and a proper assessment of the available options at the early stages in the rigid-flex PCB design phase will return significant benefits.

The Rigid-Flex PCBs fabricator must be involved early in the design process to ensure the design and fab portions are both in coordination and to account for final product variations.

The Rigid flex capabilities manufacturing phase is also more complex and time-consuming than rigid board fabrication.

All the flexible components of the Rigid Flex assembly have completely different handling, etching, and soldering processes than rigid FR4 boards.

Benefits of Rigid Flex Capabilities

Space size can be minimized

By removing the connectors and cables between rigid parts

Then you can improve board size and overall system weight

By maximizing space usage but with few parts.

Few solder joints but with higher connection reliability.

The handling of assembly is easier in comparison with normal.

Simplified PCB assembly processes.

Integrated ZIF contacts provide simple modular interfaces to the system environment.

Test conditions are simplified. A complete test before installation becomes possible.

Logistical and assembly costs are significantly reduced with Rigid-Flex boards.

It is possible to increase the complexity of mechanical designs, which also improves the degree of freedom for optimized housing solutions.
