Best Flexible PCB Design Software

Electronics have a magical ability to free us from the constraints of manual labor. With the constant evolution of technology, foldable, wearable, and miniature electronics have become ubiquitous in our daily lives, thanks to the development of flexible PCB technology.

As the demand for flexible circuits continues to grow, so does the need for advanced flex PCB design software. To aid engineers in finding suitable and professional design software, TechSparks has made it a top priority. In this article, we will explore the various options available and provide video tutorials on how to use these software to design flex PCBs.

Altium Designer

While there are many design software options available for flexible circuits, Altium Designer stands out as the ideal tool for large-scale flex PCB design projects. With a plethora of practical functions such as level design, design verification, collaboration, and more, Altium is the perfect choice for circuit projects of any size. Its user-friendly interface and advanced features, including schematic capture, component placement, routing, and design rule checking, make it easy to create high-quality, cost-effective boards.

Altium’s powerful simulation and analysis capabilities also allow designers to verify their designs before production, reducing the risk of errors. For B2B flex circuit projects, Altium’s design collaboration feature enables colleagues, electronics manufacturers, and PCB manufacturers to work together on the same project, even across different countries and states. This feature is highly sought after by design firms and those requiring design services from a manufacturer, making Altium a popular choice for many businesses.


KiCAD is an excellent free and open-source software tool for designing PCBs. The video above shows the KiCAD flexible PCB design process, and to ensure high-quality boards, TechSparks offers the following KiCAD tips.

To start, it is crucial to have a clear design plan outlining the function, size, and form of the board. This will help avoid making changes later in the design process, saving time and preventing frustration.

KiCAD’s large component library is another valuable resource that designers can utilize to save time when adding components to the schematic and board layout.

Using keyboard shortcuts is an effective way to increase productivity. KiCAD has several keyboard shortcuts that help switch between tools and pan views, saving time and smoothing the design process.

Designers can also leverage KiCAD’s automation features, such as automatic routing and design rule checking, to speed up the design process and avoid manual errors.

Lastly, it’s worth exploring the vast online community of users who have created tutorials, tips, and tricks for using the software. By learning from these resources, designers can discover new techniques and best practices for using KiCAD to design flex PCBs faster and more efficiently.


Eagle is a popular and widely used flexible printed circuit board design automation software that provides a comprehensive set of features for creating simple to complex PCBs. Here are some reasons why you should consider using Eagle for your PCB design needs:

  • Affordability: Eagle is an affordable option, making it a popular choice for students and small businesses. Its low price point makes it a frequently used software in education and for small organizations.
  • Schematic Capture: Eagle includes a schematic capture feature that allows designers to create a blueprint for the physical layout of the electrical pathways.
  • Component Placement and Routing: Eagle makes component placement and routing easier with intuitive tools that enable designers to determine the physical location of components and the electrical paths and widths on the board design.
  • Design Rule Checking: Design rule checking is a critical aspect of flexible PCB design to ensure that designs comply with specified design rules. Eagle has a design rule checking function that enables designers to verify their designs, ensuring they meet performance, reliability, and manufacturing requirements.


The saying “price reflects quality” doesn’t apply to CircuitMaker, a free FPC layout tool. Despite being free, it has a vast component library and can export industry-standard file formats, allowing seamless integration with other design tools and manufacturing processes.

CircuitMaker is open-source, making it available on different operating systems and hardware platforms, and designers can customize it according to their individual needs. With a large component library, designers can reduce the time spent on design work and ensure compliance with industry standards, reducing the risk of design errors and improving the final product’s quality.

The software is community-driven, enabling quick identification and resolution of bugs and issues. With users making their own modifications and improvements to the software, it releases updates more frequently than traditional software development models, making it a flexible and reliable choice for PCB design.
