A custom logo is one of the simplest ways to make a PCB look more professional and recognizable. Whether you're developing a personal electronics project, creating a prototype for a startup, or manufacturing products under your own brand, adding a company logo to the PCB can enhance product identity and improve brand visibility.
Many engineers assume that PCB logos are only used by large manufacturers, but that's not the case. Most PCB fabrication companies can print logos on silkscreen or copper layers at little to no additional cost. If you're using Altium Designer, there are several straightforward methods to add logos to your PCB layout.
Why Add a Logo to Your PCB?
Adding a logo offers more than just visual appeal. It can provide several practical benefits, including:
Strengthening brand identity
Improving product traceability
Creating a professional appearance
Differentiating products from competitors
Adding version or ownership markings
A well-placed logo can transform a simple circuit board into a polished, market-ready product.
Method 1: Import a Bitmap Image
Importing a bitmap image is the quickest way to place a logo on a PCB. This method is ideal for simple monochrome graphics and text-based logos.
Step 1: Prepare the Logo
Convert your logo into a monochrome BMP file before importing. High-contrast black-and-white images generally produce the best results.
Step 2: Open Your PCB Layout
Launch Altium Designer and open the PCB document where you want to place the logo.
Step 3: Access the Bitmap Import Tool
Navigate to:
Tools → Convert → Import Bitmap
This tool converts image pixels into PCB objects that can be placed on the selected layer.
Step 4: Select the Bitmap File
Browse to your BMP file and open it.
Step 5: Choose the Destination Layer
Select the layer where the logo will be displayed, such as:
Top Overlay (Silkscreen)
Bottom Overlay
Top Copper
Bottom Copper
Silkscreen layers are the most commonly used because they provide excellent visibility without affecting circuit performance.
Step 6: Adjust Image Settings
Configure parameters such as:
Scale
Resolution
Pixel size
Conversion options
Use the preview window to verify the appearance before importing.
Step 7: Position the Logo
Place the logo on the PCB and move it to the desired location. Ensure it does not interfere with components, pads, vias, or traces.
Method 2: Import a DXF File
For more detailed graphics, vector-based DXF files provide superior results.
Unlike bitmap images, DXF files maintain sharp edges and can be resized without losing quality, making them ideal for complex logos and intricate designs.
Step 1: Create a DXF Version of the Logo
Export the logo from graphic design software as a DXF file or convert an existing image using CAD conversion tools.
Step 2: Open the PCB Project
Load your PCB design in Altium Designer.
Step 3: Import the DXF File
Go to:
File → Import → DXF/DWG
Select the DXF file you wish to import.
Step 4: Assign the Layer
Choose the target layer for the logo.
If placing the logo on a copper layer, verify that sufficient clearance exists between the logo and nearby copper features.
Step 5: Scale and Position the Logo
Adjust:
Size
Rotation
Placement
Once imported, review the logo in both 2D and 3D PCB views to confirm the final appearance.
Method 3: Create a Custom PCB Library Component
If you frequently use the same logo across multiple PCB projects, creating a reusable library component is the most efficient solution.
Step 1: Create a New PCB Library
Navigate to:
File → New → Library → PCB Library
Create a new PCB library file.
Step 2: Build the Logo Footprint
Open the PCB footprint editor and create the logo using one of the following methods:
Draw the logo manually
Import a bitmap image
Import a DXF file
Step 3: Save the Library
Save the footprint as part of your company PCB library.
Step 4: Place the Logo Like a Component
The logo can now be inserted into future designs just like any other PCB footprint or component.
This method significantly reduces design time for organizations managing multiple PCB projects.
Best Practices for PCB Logo Placement
To ensure the logo appears clearly after manufacturing, consider the following recommendations:
Use Silkscreen for Maximum Visibility
Most designers place logos on the top silkscreen layer because it provides strong contrast and excellent readability.
Copper logos can create a premium appearance but may be less visible depending on the surface finish used.
Avoid Excessive Detail
Very small text, thin lines, and intricate artwork may not reproduce accurately during fabrication.
Before finalizing the design, review your PCB manufacturer's specifications for:
Minimum line width
Minimum text size
Silkscreen resolution
Copper clearance requirements
Leave Adequate Clearance
Keep logos away from:
Pads
Vias
Copper traces
Mounting holes
Component placement areas
Proper spacing helps prevent manufacturing issues and ensures the logo remains legible.
Perform a Design Rule Check (DRC)
Always run a complete Design Rule Check before generating manufacturing files.
A DRC can identify spacing violations, overlaps, and other potential issues that could affect fabrication.
Choosing Between Silkscreen and Copper Logos
Feature | Silkscreen Logo | Copper Logo |
Visibility | Excellent | Moderate |
Cost | Usually Free | Usually Free |
Detail Level | High | Medium |
Manufacturing Risk | Low | Requires Clearance Checks |
Appearance | Standard Professional | Premium and Stylish |
For most PCB projects, silkscreen logos offer the best balance between visibility and simplicity.
Conclusion
Adding a logo to a PCB is a simple yet effective way to enhance professionalism, branding, and product identity. Altium Designer provides multiple methods for incorporating logos, including bitmap imports, DXF imports, and reusable library components.
For occasional projects, bitmap or DXF imports are typically sufficient. For companies developing multiple products, creating a dedicated logo footprint library can streamline the design process and ensure consistency across all PCB layouts.
Regardless of the method chosen, always follow your PCB manufacturer's design guidelines and verify the final result using DRC checks and 3D visualization tools. A properly designed PCB logo not only improves aesthetics but also helps establish a recognizable and professional brand presence.
