How to Export Gerber files From DipTrace Software

DipTrace is a powerful PCB design software used by many electronics engineers and hobbyists. One of the crucial steps in the PCB manufacturing process is generating Gerber files, which are used by fabrication houses to produce your board. This comprehensive guide will walk you through the process of exporting Gerber files from DipTrace, ensuring that you provide accurate data for manufacturing your PCB.

Understanding Gerber Files

Before diving into the export process, it's essential to understand what Gerber files are and why they're crucial in PCB manufacturing.

What are Gerber Files?

Gerber files are a set of computer files that contain information about different layers of a PCB design. Each file represents a specific layer or aspect of the board, such as copper traces, solder mask, or silkscreen.

Types of Gerber Files

Understanding these file types will help you ensure that you're exporting all necessary information for your PCB manufacture.

Preparing Your PCB Design

Before exporting Gerber files, ensure your PCB design is complete and ready for manufacturing:

1. Finalize all component placements
2. Complete all trace routing
3. Add any necessary text or labels to silkscreen layers
4. Verify design rule compliance
5. Run a Design Rule Check (DRC) in DipTrace

DipTrace Gerber Export Settings

DipTrace offers various settings for Gerber file export. Here's an overview of key settings:

These settings can be accessed in the Gerber export dialog box within DipTrace.

Step-by-Step Export Process

Follow these steps to export Gerber files from DipTrace:

1. Open your PCB design in DipTrace PCB Layout.
2. Go to "File" > "Export" > "Gerber".
3. In the Gerber export dialog:
4. Click "OK" to start the export process.
5. DipTrace will generate the Gerber files and save them in the specified folder.

Detailed Layer Selection

Ensure you select all necessary layers for your PCB design.

Verifying Your Gerber Files

After exporting, it's crucial to verify your Gerber files to ensure they accurately represent your PCB design.

1. Use a Gerber viewer software (e.g., GerbView, CAM350, ViewMate).
2. Open each Gerber file and visually inspect the layers.
3. Check for:Correct board dimensionsPresence of all components and tracesProper layer alignmentAccurate drill holes

Common Verification Checks

Common Issues and Troubleshooting

Despite careful preparation, issues can arise during the Gerber export process. Here are some common problems and their solutions:

1. Missing Layers
2. Incorrect Scale
3. Misaligned Layers
4. Drill File Issues
5. Incomplete Board Outline

Best Practices for Gerber File Management

Following these best practices will help streamline your Gerber file workflow:

1. Use descriptive filenames
2. Create a separate folder for each PCB project
3. Include a README file with project details
4. Use version control for multiple design iterations
5. Always verify files before sending to manufacturers
6. Keep a backup of Gerber files

Frequently Asked Questions

Q1: What Gerber format should I use in DipTrace?

A1: It's recommended to use the RS-274X (Extended Gerber) format. This format is widely supported by PCB manufacturers and includes all necessary information in a single file per layer, making it easier to manage and less prone to errors.

Q2: How do I include drill information in my Gerber files?

A2: DipTrace exports drill information separately as a drill file (usually with a .txt or .xln extension). Ensure you select the option to export the drill file along with your Gerber files. This file contains information about hole locations and sizes.

Q3: My manufacturer is asking for a specific file naming convention. How can I achieve this in DipTrace?

A3: DipTrace allows you to customize the output filenames during the Gerber export process. In the Gerber export dialog, you can modify the filename for each layer to match your manufacturer's requirements. It's a good practice to check with your manufacturer for their preferred naming convention before exporting.

Q4: How can I verify that my Gerber files are correct before sending them to the manufacturer?

A4: After exporting your Gerber files from DipTrace, use a Gerber viewer software to open and inspect each file. Popular free options include GerbView and KiCad's GerbView. Check for correct board dimensions, presence of all components and traces, proper layer alignment, and accurate drill holes. Some viewers also offer DRC (Design Rule Check) capabilities for additional verification.

Q5: I've made changes to my PCB design. Do I need to re-export all Gerber files?

A5: Yes, it's best practice to re-export all Gerber files after making any changes to your PCB design, even if the changes seem minor. This ensures that all files are consistent and up-to-date. After re-exporting, perform a thorough verification of the new files to catch any potential issues introduced by the changes.
