Frequently Asked Questions (FAQ)

What file formats work best for importing logos into Altium Designer?

Vector formats like DXF and DWG provide the best results for scalable logos with clean lines and precise geometry. These formats maintain quality at any size and translate well to PCB manufacturing processes. For photographic elements or complex graphics not available in vector format, high-resolution PNG or BMP files work effectively. SVG files are increasingly supported and offer excellent scalability with smaller file sizes compared to raster formats.

How do I determine the appropriate size for my PCB logo?

Logo sizing depends on several factors including PCB dimensions, manufacturing constraints, and intended viewing distance. As a general guideline, logos should be 5-15% of the total PCB area for good visibility without overwhelming the design. Consider minimum feature sizes from your PCB manufacturer, typically 0.1-0.15mm for silkscreen elements. For text-based logos, maintain minimum character heights of 0.8-1.0mm for readability. Always verify logo legibility at the final manufactured scale.

Can I use multiple colors in my PCB logo?

Standard PCB manufacturing processes typically support single-color silkscreen printing, usually white ink on colored solder mask substrates. However, multiple colors can be achieved through creative use of different layers, such as combining silkscreen graphics with solder mask openings to expose different colored materials underneath. Some specialized manufacturers offer multi-color silkscreen options, but this significantly increases cost and complexity. For cost-effective multi-color effects, consider using layer combinations rather than multiple ink colors.

What are the most common mistakes when adding logos to PCBs?

The most frequent mistakes include inadequate consideration of manufacturing constraints, such as using features smaller than minimum manufacturing capabilities, poor layer selection that results in invisible or poorly contrasted logos, and insufficient spacing from functional circuit elements. Other common issues include incorrect scaling during import, leading to logos that are too large or small for the intended application, and failure to verify logo appearance through prototyping before production. Always validate your logo implementation with your PCB manufacturer and through prototype builds.

How do I ensure my logo doesn't interfere with circuit functionality?

Maintain adequate clearance between logos and functional circuit elements, particularly high-frequency signal paths, power distribution areas, and sensitive analog circuits. Avoid placing conductive logo elements where they might create unintended electrical connections or interfere with electromagnetic compatibility. When using copper layers for logos, ensure proper electrical isolation and consider the impact on impedance control and signal integrity. Always perform design rule checks and coordinate with your circuit design team to verify that logo placement doesn't compromise electrical performance or manufacturability.
