Flex Circuit Board Manufacturers: Key Players Enabling Next-Gen Electronics


Flex circuit boards, also known as flexible printed circuit boards (FPCBs), are essential components in modern electronics. As devices become smaller and more compact, flex circuits provide the perfect solution for packing multiple interconnects into tight spaces. With their ability to bend and flex, these boards can take on nearly any shape. This allows them to fit into the smallest places while still maintaining electrical connections.

The global market for flex circuit boards continues to grow each year. As new technologies emerge, flex circuits enable innovation across industries like consumer electronics, automotive, aerospace, medical devices, and more. Leading tech companies rely on flex circuit board manufacturers to produce these critical components that power their cutting-edge devices.

In this article, we’ll highlight the key players among flex circuit board manufacturers. We’ll look at major companies, discuss their capabilities, and reveal why they are go-to suppliers for flex circuit production.

Major Flex Circuit Board Manufacturers

Several large manufacturers dominate the flex circuit board market. They possess advanced production capabilities and decades of experience serving top tech brands. Here are some of the heavy hitters when it comes to flex circuit manufacturing:

Flexium utilizes the latest cutting-edge equipment and processes for high-volume production. This includes photolithography, precision etching, and advanced lamination. Their experience serving tier-one companies has made them a premier flex circuit supplier.

Compass Technology Company

With over 30 years in the industry, Compass Technology excels at prototyping and medium volume production of complex flex circuits. They are known for their engineering expertise which allows them to manufacture innovative designs. Their domestic US production and engineering teams enable close collaboration with customers.

MFS Technology

MFS Technology has design, engineering, and manufacturing capabilities for flex and rigid-flex circuits. They specialize in producing multilayer flex circuits of over 20 layers. Their expertise includes boards for medical, military, aerospace, and telecommunications applications. MFS utilizes the latest CAD tools and production processes.

Flexible Circuit Technologies

Flexible Circuit Technologies (FCT) offers full turnkey services for taking flex circuit designs from concept to high-volume production. They leverage a digital platform with design-for-manufacturing tools to optimize yields. FCT has a global footprint with 10 manufacturing sites across America and Asia. This allows them to scale production.


As the largest flex circuit manufacturer in China, DSBJ has extensive capabilities for rigid, flex, and rigid-flex designs. They have over 5000 employees worldwide. By wholly owning their supply chain, they can deliver volume production of up to 1 million boards per month. Their expertise includes consumer electronics, automotive, and industrial applications.

Capabilities of Leading Flex Board Manufacturers

To meet the needs of their customers, top flex circuit board manufacturers offer a range of specialized capabilities:

Expert Design Support

The best flex circuit suppliers have engineering teams that provide design for manufacturing (DFM) services. This includes circuit optimization, layer stackup, and layout adjustments to ensure manufacturability and reliability. They use advanced modeling and analysis tools to perfect designs.


Leading flex circuit companies enable fast prototype production using the same processes as volume manufacturing. This allows customers to test out designs rapidly without slow tooling cycles. Fast prototyping minimizes risk and speeds time-to-market.

Precision High-Volume Production

Flex circuit manufacturers utilize automated tooling and processes for precision production. Cutting-edge equipment like laser direct imaging (LDI) improves yields for complex board layouts. Electrodeposition can build up layers avoiding lamination issues.

Rigid-Flex Capabilities

Many flex circuit suppliers offer specialized services for rigid-flex boards. These combine rigid sections for connectors and components with flexible folds in between. Rigid-flex requires advanced lamination processes to bond distinct materials.

Testing and Validation

To ensure reliability, quality flex circuit partners have extensive testing capabilities. This includes electrical testing, vibration/shock testing, environmental stress screening, and more. They validate performance before boards get shipped to the customer.

Frequently Asked Questions About Flex Circuit Manufacturers

Q: What are some examples of products that use flex circuits?

A: Flex circuits are found in all types of consumer electronics, including cell phones, laptops, tablets, wearables, and more. They also enable medical devices, aerospace systems, automation, IoT, and automotive electronics. Any application where dense, reliable interconnects are needed in tight spaces uses flex circuit boards.

Q: Why are flex circuits better than traditional PCBs for some applications?

A: Unlike rigid boards, flex circuits can bend, fold, and flex dynamically to fit into tight spaces in devices. This allows packing more interconnects in a smaller form factor. And unlike wires or cables, flex circuits don’t fatigue nearly as easily from repeated bending.

Q: What types of companies typically work with flex circuit manufacturers?

A: Any companies building electronic devices from large consumer product companies to medical OEMs partner with flex circuit manufacturers. Startups developing new tech products also benefit from leveraging flex circuit vendors’ expertise.

Q: How are flex circuits manufactured and assembled?

A: Manufacturing begins with chemical etching of the copper traces onto a thin polyimide substrate film. Additional layers are bonded through precise alignment and lamination. Components are then assembled onto the boards using soldering or adhesive methods.

Q: How long does it take to manufacture flex circuits?

A: The production timeframe depends on complexity, layer count, and order volume. Simple prototypes can be produced in 5-7 days. For complex designs in production volumes, the cycle time is typically 8-12 weeks. Experienced vendors have techniques to expedite delivery.
