# Never Worry About Stackups Again: Introducing the Stackup Editor

Stackup Editor: a new and improved way to select your PCB stackup that requires less time, less effort, and is less prone to errors.

[![Screenshot of Flux.ai's PCB design software interface showing the 'Stackup Editor' for a 'PCBWay 4 Layer' circuit board. The detailed editor displays a list of layers with their specific properties including name, orientation, type, material, thickness, weight, and dielectric constant. The configuration includes 'Top Copper,' 'Mid-Layer 1,' 'Mid-Layer 2,' and 'Bottom Copper,' each with specified materials like copper and prepreg, as well as the thicknesses for additional 'Top Overlay,' 'Top Solder Paste,' and 'Top Solder Mask.' Each layer is distinctly color-coded and sequentially numbered. The interface has a modern, sleek look and is set against a cosmic backdrop, enhancing the visual experience of PCB design.](https://www.flux.ai/p/assets/blogs/stackup_editor/main.webp)](#)

## Why is determining your PCB’s stackup always one of the most confusing parts of the design process? We were tired of doing all of the hard design work only for PCBs to fail because of errors in the stackup, so we decided to change the way this whole process works.

## Today, we’re launching our Stackup Editor: a new and improved way to select your PCB stackup that requires less time, less effort, and is less prone to errors.

### An Improved Stackup Workflow

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?

![Flux app showing how to add and modify any layers in your printed circuit board stackup configuration](https://www.flux.ai/p/assets/blogs/stackup_editor/stackup_editor_1.gif)

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. 

### A Central Hub for the Hardware Industry

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. 

![Flux app showing how to easily select pre-definted default stackup configurations from top pcb manufacturers so you can get started quickly, also showing here is the ability to create your own custom pcb stackup configurations](https://www.flux.ai/p/assets/blogs/stackup_editor/stackup_editor_2.gif)

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:

-   [JLCPCB multi-layer stackup](https://www.flux.ai/jharwinbarrozo/multi-layer-jlcpcb-constraints)
-   [PCBway 4-layer stackup](https://www.flux.ai/jharwinbarrozo/pcbway-4-layer-stackup)
-   [Seeed Studio 4-layer stackup](https://www.flux.ai/seeedstudio/seeed-studio-4-layer-stackup)
-   [OSHPark 4-layer stackup](https://www.flux.ai/jharwinbarrozo/4-layer-oshpark-constraints)

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.

### Another Step Forward

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. 

If you want to get hands-on with the Stackup Editor, [check out some of our templates](https://www.flux.ai/sitemap/project-templates/stackups) and get started today!
