PCB Assembly Service Providers that Accept ODB ++ Files

By Prototype PCB Assembly · Updated August 19, 2024

What is ODB++ and Why is it Important for PCB Assembly?

ODB++, which stands for Open Database++, is a comprehensive PCB CAD data exchange format. It was developed by Valor Computerized Systems (now part of Mentor Graphics) to provide a single data structure for transferring PCB design information between different EDA/ECAD applications and manufacturing.

ODB++ has become a widely adopted industry standard for PCB fabrication and assembly data exchange. It offers several advantages over traditional Gerber files and NC drill files:

• Intelligent data format that includes netlist, component, and placement information
• Allows for more automated and streamlined PCB fabrication and assembly
• Supports embedded components and complex PCB structures
• Enables more comprehensive design rule checks (DRC) and validation

For PCB designers and engineers, using ODB++ provides assurance that their design intent will be accurately conveyed to the manufacturer. It helps avoid errors and ambiguities that can occur with Gerber files.

PCB assembly service providers that accept ODB++ files are able to provide a more seamless, efficient, and reliable manufacturing process. The intelligent data in ODB++ allows them to automate many steps and catch potential issues early on.

How to Generate ODB++ Files from Your PCB Design Software

Most major PCB design tools have the capability to export ODB++ files. The specific steps will vary depending on the software you are using. Here are general instructions for some popular PCB design applications:

Altium Designer

1. Go to File -> Fabrication Outputs -> ODB++
2. Configure the desired output settings
3. Specify the output location and click OK to generate the ODB++ file

Cadence Allegro

1. In PCB Editor, go to File -> Export -> ODB++
2. Set the desired options and click OK
3. Choose the output destination and click Export

Mentor Graphics PADS

1. Go to File -> Export -> ODB++
2. Configure the layer mapping and other options

Preparing Your ODB++ Design Package for Manufacturing

Once you have generated your ODB++ file, there are a few additional steps to take before sending it off to your assembly partner:

1. Review the ODB++ file: Open your ODB++ file in a viewer tool to make sure all the layers, drilling, and other design elements are correctly represented. Some free ODB++ viewer options include Mentor Graphics ODB++ Viewer and Ucamco ODB++ Viewer.

2. Generate a README file: Create a plain text README file that includes any special instructions, notes, or requirements for your PCB assembly. This could include information about unique components, testing requirements, packaging, etc.

3. Package the design files: Zip up your ODB++ file, README, and any other relevant design files (BOM, Centroid file, etc.) into a single compressed archive. This makes it easy to transfer everything to your assembly partner.

4. Send to your manufacturer: Upload your design package to your assembly partner’s web portal or FTP site. If you’re working with a new manufacturer, be sure to confirm their preferred method for receiving design files.

By properly preparing your ODB++ design package, you can ensure a smooth handoff to manufacturing and minimize the risk of delays or confusion.

Benefits of Working with an ODB++-Capable Assembly Partner

Choosing a PCB assembly service provider that can handle ODB++ files offers several key advantages for your manufacturing process:

1. Improved accuracy: ODB++ provides a more complete and intelligent representation of your PCB design compared to Gerber files. This helps ensure that your manufacturer will accurately fabricate and assemble your boards to your specifications.

2. Faster turnaround times: The intelligent data in ODB++ enables a more automated and streamlined manufacturing process. This can translate to shorter lead times and faster delivery of your assembled PCBs.

3. Better design for manufacturability (DFM): ODB++ files allow your assembly partner to perform more comprehensive DFM checks. They can catch potential issues early on and provide feedback to help optimize your design for manufacturing.

4. Reduced errors and rework: By using ODB++ to convey your design intent, you can minimize the risk of misinterpretation or ambiguity that can lead to manufacturing errors and the need for rework.

5. Easier communication: ODB++ provides a standardized format for exchanging PCB design data. This can simplify communication with your manufacturing partner and reduce the chances of misunderstandings.

By leveraging the capabilities of ODB++, you can achieve a more efficient, reliable, and cost-effective PCB assembly process.

Frequently Asked Questions

1. What if my PCB design software doesn’t support ODB++ output?

If your current PCB design tool does not have the ability to generate ODB++ files, you have a few options:

• See if there is an add-on or plugin available that enables ODB++ output
• Export Gerber and NC drill files, then use a third-party tool to convert them to ODB++ format
