Through real-world examples such as high-temperature delamination in medical equipment, five-stage reflow soldering for military orders, and battery management systems for new energy vehicles, this article reveals the crucial roles of polyimide substrates and rolled copper foil in stability and reliability. Material selection may seem like a cost issue, but it's actually a core factor affecting product lifespan and performance, worthy of in-depth consideration by the industry."}
