How can you improve PCB manufacturability with CAD software?

2 Follow the best practices for PCB design

Even with the best CAD software, you still need to follow the best practices for PCB design to ensure its manufacturability. This includes choosing the right materials, components, layout, routing, and testing methods, as well as following industry standards and guidelines. For instance, use a grid system to align components and traces, making sure they are not too close or too far from each other. Additionally, use vias and pads that are compatible with fabrication and assembly methods. Trace widths and clearances should handle current and voltage requirements while avoiding loops or sharp angles that could cause interference or noise. A ground plane provides a stable reference for signals but avoid creating islands or slots that could break its continuity. Multilayer PCB design should only be used when necessary, avoiding excessive or uneven layer stacking that could affect thermal and mechanical properties. Finally, a test plan should be used to verify the design before sending it to the manufacturer; this plan should include test points, probes, and fixtures to facilitate the testing process.

3 Communicate with your manufacturer

One of the most important steps to improve your PCB manufacturability is to communicate with your manufacturer. Your manufacturer can provide you with valuable feedback and suggestions on how to optimize your PCB design for their capabilities and processes. You should consult with your manufacturer as early as possible in your design cycle, and share your design files, specifications, and requirements with them. You should also ask them about their quality standards, tolerances, and inspection methods, and make sure that your PCB design meets their expectations and complies with their rules. By communicating with your manufacturer, you can avoid any misunderstandings, errors, or delays that could affect your PCB manufacturability.
