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
Micro heaters are widely used in the fields of gas sensors, gas galvanometers, infrared light sources, and collection of fine particles. Recently, micro heater for gas sensor usually use platinum as it's electrode material. This paper aims to improve the wearability of flexible gas sensors. Because graphene has high thermal conductivity, low convective heat coefficient, and good toughness, it has ...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
