Everyone wants smaller boards, higher density, and lower cost\u2014but routing physics does not disappear just because layouts become tighter.<\/p>\n\n\n\n<p>So, how close <em>can<\/em> components realistically be to the PCB edge when using milling depaneling? The answer is not a single number. It depends on how manufacturers define acceptable yield, as well as their process control standards and risk tolerance in real production.<\/p>\n\n\n\n<p>This article shares experience-based insights from global SMT lines, focusing on manufacturability, cost impact, and practical design\u2013process coordination rather than theoretical limits.<\/p>\n\n\n\n<div id=\"ez-toc-container\"
