PCB Design Checklist

Author: NCAB Group

This comprehensive PCB Design Checklist ensures design accuracy and manufacturability prior to production. It covers 12 key areas: component packaging, placement, mechanical checks, technical checks, constraint rules, routing, timing design, power design, DRC checks, test pins, silkscreen, and Gerber review. Each section includes detailed sub-checks, such as verifying solder mask dimensions, component spacing, signal routing, impedance control, safety clearances, and test point alignment. Emphasis is placed on utilizing 3D models, panelizing small boards, and performing design rule checks (DRC) to catch errors. This checklist ensures a thorough review, minimizing design flaws and optimizing both functionality and production readiness.

PCB Design Tips

Author: NCAB Group

This comprehensive guide to is aimed at avoiding 13 common PCB design mistakes, such as issues with annular rings, improper spacing between plated/non-plated holes and copper, trace width mismatches, stubs, slivers, copper-to-edge clearance, and solder mask/legend print problems. Each mistake is detailed with its associated risks alongside solutions and references IPC standards and best practices. Key recommendations include adhering to proper tolerances, maintaining correct clearances, using accurate CAD settings, and collaborating with PCB suppliers. The aim is to ensure high-reliability PCBs by addressing design flaws early, minimizing production challenges, and enhancing overall manufacturing yield and quality.
