The importance of pre-delivery prep in PCB assembly is often overlooked, leading to mistakes and delays. To ensure success, it’s crucial to know your basic assembly specs, include all parts, and provide complete Gerber files. Additionally, pay attention to the silkscreen, add a Bill of Materials, consider shipping insurance, and choose the right manufacturer. Understand the fabrication process, provide all necessary files, ensure component availability, select the right white labeling method, and carefully choose LED colors and placements. Lastly, choose fonts carefully and follow this checklist to ensure a successful prototype board assembly.
