Through practical case studies, this article explores how the thickness of the insulating layer impacts reliability\u2014examining, for instance, the differing requirements found in LED automotive lighting and power supply modules. It also highlights the critical importance of filler uniformity, noting that uneven distribution can lead to localized heat accumulation and compromise overall performance. Drawing upon real-world engineering practices, this guide helps readers avoid common design pitfalls."}
