Designing a PCB is no longer limited to large engineering companies with expensive EDA software.
Today, individual engineers, students, makers, startups, and small engineering companies can design professional PCBs using a variety of tools.
The important question is:
Which PCB design software is appropriate for a small company or an individual engineering project?
There is no single answer for every project. The right choice depends on the complexity of the PCB, mechanical design requirements, collaboration needs, simulation requirements, manufacturing workflow, and software budget.
In this article, we will compare several commonly used PCB design tools and take a closer look at Autodesk Fusion, including my own experience using Fusion for electronics and PCB projects.
1. What Does PCB Design Software Need to Do?
Modern PCB design software generally provides several major functions:
- Schematic capture
- Component libraries
- PCB layout
- Component placement
- Copper routing
- Design Rule Checking (DRC)
- Electrical Rule Checking (ERC)
- PCB 3D visualization
- Gerber generation
- BOM generation
- Manufacturing documentation
- Simulation
- Mechanical integration
A typical workflow looks like this:
Electronic Concept
↓
Schematic
↓
Component Selection
↓
PCB Layout
↓
Routing
↓
DRC / ERC
↓
3D Mechanical Check
↓
Gerber / Manufacturing Files
↓
PCB Manufacturing
↓
Assembly & Testing
The more complete the software workflow, the less manual work is required when moving from an electrical design to a manufactured product.
2. Popular PCB Design Software
Several PCB design platforms are commonly considered by engineers and designers.
Examples include:
-
- KiCad
- Autodesk Fusion Electronics
- Altium Designer
- EasyEDA
- Other specialized ECAD/EDA platforms
Each tool has a different design philosophy.
For example, KiCad is a free and open-source EDA suite that includes schematic capture, PCB layout, 3D visualization, simulation, and manufacturing data export.
Autodesk Fusion combines electronics design with mechanical CAD, simulation, manufacturing, and cloud-based collaboration.
Altium is another professional ECAD platform commonly used for more advanced PCB development, particularly in professional engineering organizations.
3. KiCad
KiCad is a free and open-source PCB design suite.
Its current platform includes:
-
- Schematic Editor
- PCB Editor
- SPICE simulation
- 3D Viewer
- Component libraries
- Design-rule checking
- Manufacturing data generation
KiCad runs on Windows, macOS, and Linux. The official KiCad documentation describes the software as a free and open-source EDA suite with schematic capture, PCB layout, simulation, 3D rendering, and manufacturing-data export.
Why KiCad is attractive for individuals
For an individual engineer, hobbyist, or small startup, one important advantage is the ability to develop PCB projects without purchasing a traditional high-cost commercial EDA license.
It is particularly useful for:
-
- Personal projects
- Prototypes
- Arduino/MCU boards
- Sensor boards
- Small embedded systems
- Open-source hardware
- Startup prototypes
KiCad considerations
KiCad is powerful, but users coming from commercial CAD environments may need some time to learn its workflow.
The component library and design-management workflow also require attention as projects become larger.
4. Autodesk Fusion Electronics
Autodesk Fusion takes a somewhat different approach.
Instead of treating PCB design and mechanical design as completely separate workflows, Fusion integrates electronics and mechanical CAD in the same environment.
Autodesk describes Fusion Electronics as supporting schematic design, PCB layout, routing, simulation, manufacturing outputs, and ECAD-MCAD integration.
This can be particularly useful when designing a product that includes both:
-
- PCB
- Enclosure
- Mechanical components
- Mounting holes
- Connectors
- Displays
- Buttons
- Heat sinks
- Cables
5. My Experience With Autodesk Fusion
Why I Used Fusion for PCB Projects
In my own electronics development work, I have used Autodesk Fusion for PCB-related projects.
One feature I found particularly useful was the relationship between the PCB design and mechanical design.
For a real product, designing the PCB alone is not enough.
The board must physically fit inside the final product.
For example:
The PCB must account for:
-
- Board dimensions
- Mounting holes
- Connector locations
- Component height
- Display position
- Button position
- Cable access
- Enclosure clearance
- Heat-generating components
Fusion’s ECAD-MCAD integration is designed to allow electrical and mechanical aspects to be developed together.
6. Why ECAD-MCAD Integration Matters
One of the biggest advantages of an integrated environment is reducing mechanical surprises late in the design process.
Imagine designing a PCB and sending it to manufacturing.
Later, you discover:
“The PCB fits electrically, but the connector cannot reach the enclosure opening.”
Or:
“The capacitor is too tall for the enclosure.”
Or:
“The mounting hole interferes with another mechanical component.”
These problems can result in additional PCB revisions.
An integrated ECAD-MCAD workflow can help engineers identify these issues earlier.
Autodesk Fusion supports PCB layout together with 3D mechanical design, allowing engineers to check board fit, component clearance, and enclosure constraints during development.
7. Fusion PCB Design Workflow
A typical Fusion Electronics workflow is:
Schematic
↓
Component Selection
↓
PCB Layout
↓
Component Placement
↓
Routing
↓
DRC
↓
3D PCB
↓
Mechanical Integration
↓
Manufacturing Output
Fusion also provides synchronization between schematic and PCB design, DRC tools, component libraries, SPICE simulation, and manufacturing output capabilities.
Autodesk’s documentation describes the workflow as schematic capture, PCB layout, and manufacturing-output generation, including Gerber and other production files.
For a small company or individual engineer, these two tools can be considered for somewhat different workflows.
| Feature | KiCad | Autodesk Fusion |
|---|---|---|
| Schematic | Yes | Yes |
| PCB Layout | Yes | Yes |
| 3D PCB | Yes | Yes |
| SPICE | Yes | Yes |
| DRC | Yes | Yes |
| Manufacturing files | Yes | Yes |
| Mechanical CAD | Separate workflow | Integrated |
| ECAD-MCAD integration | Available through workflows/tools | Core feature |
| Open source | Yes | No |
| Personal/small-project use | Strong fit | Strong fit |
| Product enclosure design | Separate CAD may be needed | Integrated |
| Cloud collaboration | Not the primary design model | Integrated cloud platform |
KiCad’s official documentation confirms its schematic, PCB, simulation, 3D, and manufacturing capabilities. Fusion’s official documentation emphasizes the integrated electronics/mechanical workflow and cloud collaboration.
8. What About Altium Designer?
Altium Designer is another professional PCB design platform.
It is commonly considered when projects require sophisticated PCB design workflows and professional engineering collaboration.
For example, a company developing complex:
-
- High-speed digital systems
- Multi-layer PCBs
- Advanced embedded systems
- Industrial controllers
- Networking equipment
- Complex power electronics
may require a more advanced professional ECAD environment.
However, software selection should consider the actual project requirements rather than simply selecting the most feature-rich tool.
For a one-person engineering project, the learning curve, workflow complexity, and licensing cost can be just as important as the feature list.
9. What About EasyEDA?
EasyEDA is another option worth considering for quick PCB development and prototyping.
Its browser-oriented workflow can be attractive when an engineer wants to move quickly from schematic to PCB.
It can be useful for:
-
- Quick prototypes
- Small electronic projects
- Maker projects
- Simple embedded boards
- Rapid PCB manufacturing
However, for a long-term engineering project, I would also consider factors such as:
-
- Project file management
- Library management
- Offline workflow
- Mechanical integration
- Version control
- Manufacturing requirements
- Team collaboration
These factors become increasingly important as the project grows.
10. Which Software Fits a Small Engineering Company?
Instead of asking:
“Which PCB software is the best?”
A better engineering question is:
“Which software fits my project requirements?”
Consider the following situations.
Individual Engineer / Hobby Project
Important factors may include:
-
- Low software cost
- Easy learning
- PCB manufacturing support
- 3D visualization
- Component libraries
KiCad can be an attractive option because it is free and open source.
Small Product Development Company
Important factors may include:
-
- PCB design
- Mechanical design
- Enclosure design
- Manufacturing
- Revision management
- Collaboration
Fusion can be particularly relevant when electrical and mechanical design need to remain closely connected.
Advanced Professional PCB Development
For complex products, engineers may evaluate professional ECAD platforms such as Altium and other enterprise-oriented tools.
The decision should consider the PCB complexity, team size, required workflows, manufacturing requirements, and existing engineering processes.
11. My Practical Approach
Based on my experience with electronics development, I would divide the selection process into three questions.
Question 1: How complicated is the PCB?
For a relatively small board:
MCU
+
Sensors
+
Power Supply
+
Communication
+
Connectors
a lightweight or open-source tool may be sufficient.
For a complex multi-layer board with high-speed interfaces, controlled impedance, dense routing, and extensive design constraints, more advanced ECAD capabilities may become important.
Question 2: Does the PCB need to fit inside a mechanical product?
If the answer is yes, mechanical integration becomes much more important.
For example:
PCB
↓
Enclosure
↓
Connector
↓
Display
↓
Button
↓
Mounting
This is one area where my experience with Fusion has been particularly useful.
Question 3: Who is going to maintain the project?
A PCB is rarely finished after the first prototype.
A product may go through:
Prototype V1
↓
Test
↓
Problem Found
↓
PCB Revision
↓
Prototype V2
↓
Production
↓
Production Revision
Therefore, project management, version control, libraries, documentation, and manufacturing files are important considerations.
12. My Recommendation for a Small Project
For a personal electronics project or small startup, I would first evaluate KiCad and Autodesk Fusion based on the type of project.
If the project is primarily:
Electronics → PCB → Manufacturing
KiCad provides a capable free/open-source workflow.
If the project is:
Electronics + PCB + 3D enclosure + Mechanical Design + Manufacturing
Fusion’s integrated ECAD-MCAD environment can be particularly useful.
For more complex professional PCB development, additional commercial ECAD platforms can be evaluated according to the team’s requirements.
13. Final Thoughts
PCB design software is an engineering tool, not simply a drawing program.
The real goal is to move from:
Concept → Circuit → PCB → Mechanical Product → Manufacturing → Testing
with as few errors and revisions as possible.
My experience with Autodesk Fusion showed me the value of connecting PCB design with mechanical design, especially when developing a complete product rather than just a bare circuit board.
At the same time, KiCad provides a strong option for engineers who want a free and open-source PCB design environment.
The best software choice depends on the project.
Choose the PCB design tool based on the engineering workflow—not simply the number of features.
