Common PCB DFM Violations and How to Fix Them
PCB Design for Manufacturing (DFM) violations are one of the main causes of production delays, low yield, and reliability failures. This guide outlines the most common PCB DFM issues, including trace width violations, via design errors, solder mask problems, and panelization mistakes. Each section explains the root cause of the issue and provides practical solutions aligned with real PCB fabrication capabilities. By identifying and correcting DFM violations early, engineers can improve manufacturability, reduce cost, and ensure stable production performance.
