The Mechanism of Humidity’s Impact on the Thermal Resistance of Power Semiconductor Chip Solder

The Mechanism of Humidity's Impact on the Thermal Resistance of Power Semiconductor Chip Solder

Abstract In recent years, the impact of humidity on the thermal characteristics of power devices has become a hot topic. However, the effect of humidity on the thermal resistance of power device chip solder has not been experimentally verified, and the mechanism remains unclear. This paper proposes, for the first time, the mechanism by which … Read more

Maximum Precipitation Height

Maximum Precipitation Height

This article mainly references the mathematical model established by Fu Baopu (1992) in “The Impact of Topography and Altitude on Precipitation,” which reflects the relationship between precipitation, topography, altitude, and climatic conditions, to solve for the altitude at which precipitation in mountainous areas reaches its maximum value. No detailed formula derivation will be provided, this … Read more
