basic information
With the miniaturization of electronic components and the increase in the number of layers in printed circuit boards, most of the heat from electronic components has begun to escape through the substrate. Therefore, "thermal design of the substrate" has become extremely important for controlling the temperature of electronic components and ensuring their reliability. Furthermore, as the connections between the substrate and components have become finer and structurally weaker, various issues have arisen due to thermal deformation and thermal fatigue caused by high temperatures. Additionally, in recent power devices, large currents are flowing through resin substrates, exposing the substrate and components to high temperatures due to Joule heating. To address this series of thermal issues related to substrates, it is necessary for circuit and substrate designers to acquire basic thermal design knowledge and incorporate countermeasures during the design phase. This lecture will explain how to approach thermal design of substrates for those who do not have knowledge of heat transfer.
