What is a Rigid Flex PCB?

A rigid flex printed circuit board integrates both flexible circuits and hardboards. Also, this PCB has the benefits of both rigid PCb and flexible circuits. Most of these boards comprise several layers of flex circuits attached to hardboards. Also, rigid flex printed circuit boards are suitable for use in different applications like aerospace and military.

Furthermore, rigid flex PCBs are usually fabricated with a wide array of several materials to meet performance requirements. Some of the materials used in the fabrication of these boards include prepreg core, cover layers, and copper foil.

The substrate material of a rigid flex circuit determines their performance. Also, the substrate material comprises of adhesive and flexible dielectric films. The flexible dielectric film usually consists of polyester, PTFE, and polyimide.

Furthermore, rigid flex circuits don’t remain in a fragile state. They rather remain in a state of a curve. Also, rigid flex printed circuit boards have a shape similar to that of a spring. These boards go back to their original state when compressed or stretched. The combination of flexible PCB and rigid PCB in rigid-flex boards gives it more advantages over flexible circuits and rigid circuits.

Types of Rigid Flex PCB

Single sided

A single sided rigid flex PCB features one conductive layer on which components are carefully placed. Also, this board is applicable in low component density applications.

Double sided

The double sided rigid flex board has two different layers. These layers can transfer electrical signal and as such, enhance component density.

Multilayer  

A multilayer rigid flex circuit features several layers that increase component density and allow ground and power separation. Also, this board helps to reduce electromagnetic interference when used in high frequency applications.

Rigid Flex PCB Manufacturing Process

This manufacturing process involves several steps which include:

Base material preparation

This involves cleaning and preparing the laminate. Cleaning the laminate is crucial since copper foils usually have anti-tarnish features to prevent oxidation.

Circuit pattern generation

This step involves two different techniques which are screen printing and photo imaging. Screen printing is more popular. It generates the deposits directly on the laminate’s surface.

Circuit pattern etching

This involves dipping the laminate in an etch or spraying with an etch solution. Also, you must etch both sides of the laminate to get desired outcome.

Drilling

Here, drilling tools create precise holes in the board. Also, laser drilling techniques help to drill very small and precise holes.

Through hole plating

This step requires extreme care and precision. Here, the manufacturer deposits copper on the already drilled holes. Also, this helps to create layer to layer electrical interconnection.

Cover lay application

You must protect the bottom and top side of the flexible PCB. Applying a cover lay on the flexible PCB will help to achieve this. Rigid flex PCB manufacturers always integrate a polyimide film and adhesive.  Screen printing helps to imprint cover lay on the surface of the board.

Cutting out the flex

Another important step in rigid flex PCB manufacturing is cutting out the flex board from the panel.

Electrical testing

This is the final step in rigid flex PCB manufacturing. The rigid flex circuits pass through strict electrical testing to ensure circuit performance and quality.

Benefits of Rigid Flex Circuits

Rigid flex circuit boards are widely used across several industries due to the benefits they offer. Asides from connecting other circuits, rigid flex printed circuit boards have a lot of advantages.

Compactness and flexibility

Rigid flex PCB design is very compact and flexible. Therefore, this makes it suitable for developing more portable devices.  Also, its compact and flexible design of this board helps to reduce overall system weight.

Customizability

Not all PCBs are customizable. It is possible to customize shape and size of rigid flex circuit boards to fit the device. This means that if you are having challenges on making a proper board for a design, you can design a rigid-flex circuit to fit the device. Also, rigid flex printed circuit boards are a popular choice among mobile phone manufacturers due to the flexibility it offers.

Heat absorption capability

Rigid flex printed circuit boards can absorb more heat due to the technology integrated in these circuits. Furthermore, the integration of polyimide in rigid flex PCB fabrication makes it resistant to heat, radiation, and UV rays.

Ease of assembly

Rigid flex circuit boards are very easy to assemble. Also, it is easier to handle these circuits during assembly. In addition, the use of ZIF connectors in the assembly enables modular interfaces to the environment of the system.

Combined technologies

Rigid flex PCB fabrication involves the combination of rigid boards and flex PCB. Therefore, this technology enables this board to feature the best flexible and rigid circuitry. This means a rigid flex PCB can offer the benefits that come with a rigid and flex circuit. Also, a rigid flex board will give manufacturers the strength of these two circuits without having their drawbacks.

Challenges of Rigid Flex PCB Assembly

flex board design

Rigid flex PCB assemblers are likely to experience some challenges when fabricating a rigid flex circuit. Below are some challenges commonly associated with rigid flex PCB assembly.

Conductor stress points

It is difficult to create stress points in rigid flex circuits. This is because trace layouts like acute junctures are incompatible with flex circuit sections.

Stacked traces

Ensure you keep the copper in the neutral axis of your flex circuit. Also, stacked traces can make the external to the bend radius to shatter.

Solder pad spacing

It is crucial to create bigger openings for a soldermask during rigid flex PCB fabrication. Shorts can occur when the assembler routes close conductor traces tightly with solder pad. Therefore, the boundaries of the close traces become exposed.

Solder joints proximity

There is solder joint formation when solder joins to the copper trace. When such a joint is in proximity to a bend, this can make the pad to split.

Conclusion

Rigid flex suppliers specialize in the fabrication of rigid flex boards. The fabrication process of these boards requires precision and carefulness. Therefore, it is important to leave your rigid flex circuit board project in the hands of a professional.
