This article proposes a network-based 3-D thermal network (TN) model for permanent magnet (PM) machines with the surface-attached cooling structure (SACS). This model is developed based on the network topology method. It combines detailed radial and axial thermal information and discretizes the motor structure into highly discrete thermal components. In this way, highly accurate results are obtain...Show More
In semiconductor lasers, chip heat dissipation is a hot topic in current research. The increase in chip temperature will not only affect the service life of the laser, but also the thermal stress will reduce the reliability of the laser. To solve this problem, this research starts with the bonding layer between the laser chip and the substrate, uses nano-silver solder paste with high thermal condu...Show More
Stretchable electronics can be summarized as an emerging electronic technology that manufactures electronic devices on flexible substrates, and has broad application prospects due to its unique ductility. In order to improve product reliability, it has become critical to understand all the failure modes that caused it to fail. Interface delamination is an important factor leading to its failure, e...Show More
At present, System in Package (SiP) is getting more and more applications in power packages. Due to the complexity of the packages, the molding process becomes crucial for the yield and reliability of the products. During the transfer molding process, the packaging processes of the packages may introduce assembly defects, such as void, wire sweep, warping, etc. To determine the main factors is one...Show More
This paper addresses the stability and reliability of IGBT operation under vibration conditions. Firstly, the structure of the module is built by soildworks; secondly, the ANSYS finite element analysis software is used as a platform to perform random vibration analysis on the structure; finally, a reasonable fatigue life calculation model is constructed based on the Conffin-Manson equation and the...Show More
In this paper, the thermal performance analysis and optimization of the package of a specific multi-heat source power device is carried out. Firstly, the finite element analysis software ANSYS Icepak is used as a tool to build a simplified model of the array type multi-power device package module. Secondly, the impact of five variable parameters on thermal performance of multi-heat source power de...Show More
