This article, based on actual workshop experience, explores the differences between theoretical parameters and actual production. For example, how minute deviations in stencil thickness can cause bridging, the significant impact of temperature and humidity changes on solder paste printing, and why equipment stability is often more important than pursuing extreme precision. Through several real-world production case studies, it shares solutions for addressing board bending, component placement misalignment, and other issues.
