![]() ![]() The most popular vendor-neutral file formats for PCB designs are Gerber files (either the standard RS-274-D or extended RS-274X), ODB++, and IPC 2581. Not only should your PCB documentation package be complete, but one must keep in mind that your manufacturer requires your package come in a format that is generally accepted by the PCB industry. The table below shows a list of output files in various categories you should be familiar with: An incomplete production documentation will most likely delay your project due to the time wasted clarifying and mitigating the issue. In this article, I'll show you how to build a complete PCB documentation package that hold to IPC standards, that a manufacturer will expect. The Basics of PCB Documentation and Manufacturing Filesįrom a manufacturer perspective, it’s a major error when your package is missing one of the documentation pieces or sets referenced in your design files. When generating a PCB footprint, your goal is to ensure your manufacturer doesn't delay production, pass on extra costs, or build a nonconforming PCB assembly. The saying “the devil is in the details” couldn’t be more true when it comes to your PCB fabrication and assembly documentation. It doesn’t take much to bring the production process to a halt with one missing PCB document that can easily blur the line of communication between what your specs are and what your PCB documentation depicts. This path of transitioning and translating your design specifications into a set of workable files for your PCB manufacturer should be straightforward, but it never is. Your PCB project is now in the “released” status with all approval signatures in place, and it’s time to hand it over to production. You just cleared through the last PCB documentation and fabrication project hurdles, whether it was securing quantities for new components, finalizing environmental testing, or getting that green light from your EMC (Electromagnetic Compliance) engineer. Getting through the PCB design and development stage is always cause for celebration. ![]()
