Gerber Files Errors Can Be Potential Show Stoppers…Here's How to Avoid These Costly Errors

 

Introduction to Gerber Files and PCB Manufacturing

Gerber files are the universal language of printed circuit board (PCB) manufacturing, serving as the critical bridge between design and production. These seemingly simple file formats hold immense power in determining the success or failure of your PCB project. Even the smallest error can lead to significant manufacturing delays, increased costs, and potentially unusable circuit boards.

Understanding Gerber Files: The Backbone of PCB Manufacturing

What Are Gerber Files?

Gerber files are standardized graphic image files that describe the layers of a printed circuit board. Originally developed by Gerber Systems Corporation (now part of Ucamco), these files contain precise instructions for PCB manufacturers, including:

• Copper layer layouts
• Solder mask layers
• Silkscreen information
• Drill holes and routing paths

The Critical Importance of Accuracy

Error Type
Potential Consequences
Estimated Cost Impact
Layer Misalignment
Complete board rejection
$500 - $2,000
Incorrect Aperture Definitions
Manufacturing delays
$200 - $800
Missing Layers
Partial or non-functional boards
$300 - $1,500
Inadequate Resolution
Poor trace definition
$250 - $1,000
Formatting Errors

$400 - $1,200

Common Gerber Files Errors and Their Root Causes

1. Layer Misalignment Errors

Layer misalignment occurs when different PCB layers are not properly registered or positioned relative to each other. This can result from:

• Incorrect export settings in design software
• Inconsistent coordinate systems
• Software-specific translation issues

Mitigation Strategies:

• Use consistent coordinate origins across all layers
• Verify layer-to-layer alignment in CAD software
• Utilize design rule checks (DRC) before file generation

2. Aperture Definition Mistakes

Apertures define the shape and size of drawing tools used in PCB manufacturing. Common errors include:

• Undefined aperture macros
• Incorrect aperture sizes
• Incompatible aperture types between design and manufacturing systems

Prevention Techniques:

• Use standard aperture libraries
• Double-check aperture definitions before file export
• Communicate directly with your PCB manufacturer about specific requirements

3. Resolution and Precision Challenges

PCB manufacturing requires extremely high precision. Errors can arise from:

• Incorrect units (mils vs. millimeters)
• Insufficient graphic resolution
• Rounding errors during file conversion

Resolution Parameter
Recommended Range
Critical Threshold
Graphic Resolution
2.4-3.5 mil
< 2.0 mil = High Risk
Coordinate Precision

< 3 mil = Manufacturing Challenge

4. Incomplete or Missing Layers

Incomplete file sets can lead to significant manufacturing complications. Always ensure you include:

• Copper layers
• Solder mask layers
• Silkscreen layers
• Drill/routing information
• Mechanical/outline layers

5. Formatting and Compatibility Issues

Different CAD systems and manufacturers may have subtle formatting differences. Potential issues include:

• Incompatible file extensions
• Non-standard coordinate systems
• Gerber version incompatibilities

Best Practices for Generating Reliable Gerber Files
