WebDec 29, 2024 · In the previous article, we learned about the concept of junction-to-ambient thermal resistance, often known as θ JA or theta JA, and how it affects the thermal performance of an IC package.. Here, we will discuss the standardized test conditions under which θ JA should be measured. This discussion will reveal that it might not be a good … WebThermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of …
