Apple and Huawei Boost Demand for Foldable Phone FPC

Apple and Huawei are accelerating the foldable phone market, creating new opportunities for FPC and flexible PCB suppliers through higher technical demands.

Introduction

 

The foldable smartphone market is entering a new stage of development as major technology companies continue to invest in new form factors. Huawei has strengthened its position with advanced foldable devices, while Apple has officially entered the foldable smartphone market.

 

This shift is attracting renewed attention to the FPC (Flexible Printed Circuit) industry. As foldable smartphones become thinner, more sophisticated, and more reliable, flexible PCBs are playing an increasingly important role in connecting components across moving and tightly packed structures.

 

For PCB manufacturers and electronics suppliers, the growth of foldable phones could create a new opportunity for high-end FPC applications.

 

 

Apple’s Entry Raises the Profile of Foldable Phones

 

Foldable smartphones have been available for several years, but adoption has remained concentrated in the premium segment.

 

Companies including Huawei, Samsung, HONOR and Xiaomi have continued to develop foldable devices, introducing book-style, flip and multi-fold designs. Huawei has also pushed the industry toward more complex tri-fold smartphone structures.

 

Apple's entry into the foldable phone market could mark another important turning point. Apple has a strong influence on the premium smartphone market. Its decision to develop foldable products may encourage more consumers to consider foldable devices while motivating competing smartphone manufacturers to accelerate their own product development.

 

For the electronics supply chain, this could mean more demand for components specifically designed for foldable applications. Among these components, FPC and flexible PCB technology deserves particular attention.

 

Why Do Foldable Phones Need FPC?

 

 

Traditional smartphones generally have a relatively fixed internal structure. Foldable smartphones are different because their internal components must accommodate movement.

 

Displays, cameras, batteries, sensors and other electronic components may be distributed across multiple sections of the device. At the same time, the hinge allows the phone to open and close repeatedly.

 

This creates a challenge for electrical connections. A conventional rigid PCB cannot easily accommodate continuous mechanical movement. FPC, by contrast, is thin, lightweight and flexible, making it suitable for connecting components across moving sections.

 

However, simply making a flexible circuit is not enough. A foldable phone FPC may need to withstand thousands or even hundreds of thousands of bending cycles while maintaining stable electrical performance. It must also fit into increasingly limited internal spaces.

 

As a result, manufacturers face higher requirements for:

 

• Bend reliability
• Flexibility and bending radius
• Circuit density
• Material performance
• Dimensional stability
• Signal integrity
• Manufacturing yield

 

This means the development of foldable smartphones is not only increasing demand for FPCs but also raising the technical requirements for flexible PCB manufacturing.

 

Tri-Fold Smartphones Could Push FPC Technology Further

 

 

The emergence of tri-fold smartphones adds another layer of complexity. A traditional foldable phone has one major folding area, while a tri-fold design introduces multiple moving sections and more complicated mechanical structures.

 

For FPC manufacturers, this can translate into more challenging routing and bending requirements. The flexible circuit must be carefully designed to avoid excessive stress during opening and closing. The position of the bending area, circuit pattern, copper thickness, coverlay and reinforcement structure can all affect long-term reliability.

 

As smartphone manufacturers continue to pursue thinner designs, the available space around the hinge is also becoming increasingly limited. This creates a clear engineering challenge:

 

How can manufacturers achieve higher reliability while making FPCs thinner and more flexible?

 

The answer will likely involve improvements in materials, circuit design and manufacturing processes rather than simply increasing production capacity.

 

From FPC Volume to FPC Value

 

One important point for the PCB industry is that the opportunity created by foldable phones should not be measured only by unit shipments.

 

The more important question is whether the FPC value per smartphone will increase. Compared with conventional smartphones, foldable devices typically require more complicated internal connections. High-end products may also require more advanced flexible circuits and rigid-flex PCB solutions.

 

This could increase the value of FPC content per device. For suppliers, therefore, the competitive advantage may increasingly come from technology rather than capacity alone.

 

Companies with strong capabilities in precision circuit manufacturing, advanced materials, high reliability testing and mass-production yield could have an advantage when competing for foldable phone projects.

 

Customer qualification is another important factor. Leading smartphone manufacturers typically have strict requirements for component reliability and production consistency. Suppliers must demonstrate that their FPC products can meet demanding specifications before entering mass production.

 

Materials Will Become Increasingly Important

 

The evolution of foldable phones is also creating opportunities further upstream in the FPC supply chain. Flexible PCB performance depends heavily on materials such as polyimide films, copper foil, coverlay and adhesives.

 

As foldable devices become thinner and their bending requirements become more demanding, material suppliers need to improve flexibility, dimensional stability, heat resistance and fatigue performance.

 

At the same time, the increasing integration of high-speed components could create additional requirements for signal integrity and electromagnetic performance. This means the foldable phone supply chain is becoming increasingly interconnected:

 

Smartphone manufacturers → FPC manufacturers → PCB materials → Copper foil and other upstream suppliers

 

The companies capable of supplying high-performance materials and stable mass-production processes could benefit as foldable devices move toward wider adoption.

 

Could Foldable Phones Become a New Growth Driver for FPC?

 

The long-term growth of the foldable phone market is still subject to several factors, including device pricing, durability, battery capacity, hinge technology and consumer demand. However, the continued investment from major smartphone manufacturers suggests that foldable phones are moving beyond the experimental stage.

 

The entry of Apple could be particularly important because it may help expand the addressable market for foldable smartphones. If foldable devices become a larger part of the premium smartphone market, FPC suppliers could benefit from both higher demand and increasing technical requirements.

 

For the PCB industry, this creates a potentially attractive combination:

 

More foldable devices + more complex internal structures + higher FPC specifications + higher value per device.

 

That combination could make foldable smartphones an important growth area for the FPC market over the coming years.

 

Conclusion

 

The competition between Apple, Huawei and other smartphone manufacturers is not only about displays, hinges or industrial design. It is also driving innovation in the invisible components inside the device.

 

FPC is one of those critical components. As foldable phones become thinner, more complex and more reliable, flexible PCB technology will need to evolve accordingly. Suppliers with strong capabilities in high-density circuits, dynamic bending reliability, advanced materials and mass-production quality could be better positioned to capture this opportunity.

 

For the PCB and electronics industry, the key question is no longer simply whether foldable phones will grow. The bigger question is:

 

How much more advanced will the FPC inside the next generation of foldable phones need to become?

 

As Apple and Huawei continue to push the boundaries of foldable smartphone design, FPC may become one of the industry's most important—and least visible—beneficiaries.
