The special FLEXOO advantage:
100% solderable Flex PCBs

As one of the few suppliers, we master the technology of manufacturing solderable flexible PCBs that eliminate the need for expensive connection methods. Here are the key reasons:

  • Standard soldering processes can be used - offering seamless integration into existing production lines
  • Zero dependency on costly crimping tools, specialized equipment, or trained assembly personnel and eliminates connection failure points that often occur with mechanical connectors
  • Solderable design allows full utilization of cost-effective inks like copper without sacrificing assembly flexibility

Our production technology enables flexible PCBs that are not only cost-effective in assembly but also provide reliability through permanent solder connections.

What Flex PCB types can FLEXOO print?

Single-sided Flex PCBs

Single-sided flexible circuit boards - ideal for cost-sensitive applications like RFID tags or simple sensors. Perfect for high-volume production at low costs.

Multi-layer Flex PCBs

For more complex circuits, we offer multi-layer flex PCBs with up to 2 layers - the perfect balance between functionality, flexibility and cost efficiency.

Does your current PCB design leave optimization potential unused? Ask us! For certain requirements - such as signal density, EMC - we can reduce the structure to up to 2 layers.

Wearable Flex PCBs

This flexible PCB technology enables seamless integration of electronic circuits into clothing, fitness bands or medical monitoring devices. FLEXOO's flex PCBs adapt perfectly to body movements without losing their functionality.

FLEXOO's printing technology enables precise conductive traces on ultra-thin, flexible substrates, creating the foundation for the next generation of wearable electronics.

Frequently asked questions about Flex PCBs

How long do Flex PCBs last compared to rigid ones?

The lifespan of Flex PCBs and rigid PCBs depends heavily on the respective operating conditions, material quality and design. Flex PCBs are designed to withstand repeated bending and movements, often providing higher durability than rigid circuit boards in dynamic applications. With optimal design and under suitable operating conditions, Flex PCBs can achieve comparable or even longer lifespans than rigid PCBs. Decisive factors include temperature, humidity, vibrations and the quality of materials used.

Can I convert my existing PCB design?

In most cases, it's possible to transfer an existing circuit board design to a flexible PCB. Of course, some important aspects must be considered, including:

- Selection of suitable materials
- Bending radius
- Placement and mounting of components
- Specific design rules for flexible circuits

Where necessary, our experts make suggestions for adjustments to optimally utilize the advantages of Flex PCB technology. Our Flex PCB specialists always seek the best solution for you.

How do you handle component assembly on flexible PCBs? Can you use standard SMD production lines?

Yes, our flexible PCBs are fully compatible with standard Surface Mount Technology (SMT) assembly processes. We use reflow-solderable inks that enable seamless integration with your existing automated SMD production lines.

Our Flex PCBs can be processed using conventional sheet-based assembly methods, allowing you to leverage your current manufacturing infrastructure without requiring specialized reel-to-reel equipment. This compatibility ensures cost-effective production scaling and maintains your established quality control processes.

The reflow soldering process works reliably with our printed conductive traces, delivering strong, durable solder joints that maintain their integrity even under repeated flexing cycles.
