From solder paste chemistry and reflow oven profiles during SMT assembly, to safe creepage clearances and thermal planning around sampling traces in PCB layout, risk hides in every step. Drawing on real project experience, this article looks at how to avoid cold joints, creepage failures, and monitoring distortion in lithium battery PCB assembly, and shares a genuinely reliable approach to validation testing."}
