Never Worry About Stackups Again: Introducing the Stackup Editor
Selecting your PCB’s stackup has always been painstaking and unintuitive. First, you have to talk to the fabrication house, who will send you their stackup capabilities and tolerances via email and PDF. Then, it’s your job to take that information and transpose it back into your design tool, double and triple-checking that you didn’t make any errors in the process. So much back and forth inevitably leads to disorganization, information loss, and sometimes even failure. Not to mention lost time in the process.
If fabrication houses have standardized stackups, why are there so many hoops to jump through just to implement them into your design?
With Flux’s Stackup Editor, we change the narrative. With a simple and intuitive interface built into the tool, the Stackup Editor gives engineers an improved stackup workflow. Just go to your PCB layout, select “Stackup” under “Object-specific rules”, and find everything you need in one centralized location.
Not only can you edit and create stackups with minimal effort, but you can now also leverage Flux’s community of over 175,000 electrical engineers to take the hard work out of the process. With thousands of projects available to you from the community, you never have to start from scratch. Instead, you can simply find a project that is similar to yours and use that stackup as a template for your own design.
Finally: stackups no longer live in your email inbox, they live in the tool. And with that, you can save yourself from the wasted time, money, and effort that has been industry-standard for far too long.
More importantly, the addition of Stackup Editor aligns with our ultimate goal of creating a single, centralized platform for all of the hardware industry to collaborate.
With the Stackup Editor, fabrication houses themselves can directly input their stackup options into Flux as templates for designers to choose from. Just go to the fabrication house’s Organization page, find a stackup template from them that matches your project, and fork it for your own design.
At launch, you can choose from dozens of Stackup templates, including:
With that kind of first-party input from the houses themselves, you can feel confident that your stackups are ready for production before you even get there.
The Stackup Editor is another massive step towards creating a single place where designers can collaborate with each other and the industry as a whole. Now Flux offers one place where you can directly access parts from suppliers, designs and references from manufacturers, and stackups from fabrication houses.

Flux Files centralizes your project docs, assets, and AI outputs in one tab so your team and AI always have the context they need.
Whether you're migrating from popular EDA applications or starting fresh, mastering high speed PCB design has never been more intuitive. Flux enables teams to design, simulate, and route with real-time AI assistance, so you can spin your next high-speed board with total confidence.
This Spring 2026 updates make hardware design faster end-to-end with a more capable, self-correcting AI agent, improved AI auto-layout that needs less cleanup, sourcing-aware design with real-time pricing and availability, and templates to start from.
This update brings more than just polish—it’s the foundation for a faster, more fluid design experience, built around the way Copilot is used today and the way we see it evolving tomorrow.
Now, Flux Copilot can learn how you work—your design principles, part selection preferences, schematic style guidelines, and testing workflows—and remember them automatically.
We're excited to unveil our Smart Polygon system in Flux! This powerful capability builds on top of our automatic copper fills to transform how you create and manage custom copper areas in your PCB designs.
Whether you’re routing high-speed buses, fine-tuning antennas, or laying out clean RF filters, sharp 90º or even 45º angles can be a serious bottleneck. Now, you can create precisely curved elbows across entire nets—or dial them in trace by trace—with full control over radius, inheritance, and overrides.
With the latest release of Copilot it isn’t just smarter—it’s hands-on, placing components and applying bulk changes to your project instantly. But to get the most out of it, knowing how to craft the right prompt is key.
