主要参与项目(Major Research Project)：

  1. Modeling and experimental behavior study on tin whisker 2016.8-2021.11
    Whiskers represented by tin whiskers are one of the most important causes of reliability degradation and failure of sensors, electrical connectors, integrated circuits, microelectronic packaging, opto-mechanical precision measurement systems, robots, data centers and other devices and systems. In particular, aerospace equipment, marine engineering equipment, military equipment, nuclear facilities and lithium batteries in special environments pose a greater and more unpredictable threat to their reliability. In this study, a finite element mathematical model and solution equation of the microstructure tin whisker growth mechanism of the system under extreme external environment and internal stress were established, an experimental system with controllable background argon pressure, sputtering time, thermal cycle temperature and duty cycle was constructed, the key factors affecting the whisker formation process and reliability were revealed, and the whisker prediction theory and control strategy based on tin atom diffusion were studied. By limiting the TEM grid, deposition thickness and area, a volume growth threshold was obtained, reducing whiskers by more than 90%.
  2. A Images Filter Based on Support Vector Machine 2012.8-2014.5
    Two image filters based on self-learning machine support vector machine (SVM) are constructed: the median filter is used to obtain training data for the support vector machine, additional data is added as training data, the performance and self-learning potential of the filter are tested, and the recognition and differentiation of regionally
    divided noise pixels and normal pixels are realized, which can filter out more than 99% of the noise pixels in the image.
  3. Experimental study of association imaging based on compressed sensing algorithm 2012.10-2013.6
    In order to test and verify the object recovery ability of compressed sensing theory and technology based on the principle of correlation imaging, an experimental system was constructed by using digital micromirror devices to preset the reference arm light field, digital micromirror equipment and single-pixel light intensity detector, and
    obtain the total light intensity information reflected by the object and restore the image of the object. A new matching tracking algorithm based on random matrix parameters is designed, and the traditional matrix-based optimization algorithm is compared and analyzed, and a further optimization strategy is proposed.
  4. An assessment of random sequence in Test Algorithm 2011.9-2012.1
    By introducing the concept of “screening capability” to simplify the formed sequence randomness test package, from the application point of view, the specific operation procedures required to simplify the test package in descending order are given, and the results are compared and analyzed.
  5. Resource Allocation and Interference Avoidance for Femtocell 2012.2-2012.6
    Introducing Shannon’s formula, a bidding mechanism for the transmission rate allocation mode of independent Nash equilibrium point is proposed, which is described in detail. Such mechanism allows relay stations to participate, provides a variety of user policies, and better meets the actual communication needs.
  6. Modeling and Experimental Study of Tin Whiskers for 3D Electronic Packaging 2018.1-2019.8
    The finite element method was used to establish a mathematical model of the growth mechanism and behavior of tin whiskers in 3D electronic packaging, and an accelerated experimental system for the relationship between internal compressive stress of thin films and whisker growth rate, length and density was constructed, the
    qualitative analysis of whiskers was realized, and the quantitative testing of whisker growth rate and density was realized by scanning electron microscopy.
