Latest Patents

Zhang's latest patents include a revolutionary SnBiSb series low-temperature lead-free solder and its preparation method. This invention is particularly remarkable as it supports the transition to lead-free alternatives in soldering, crucial for environmental safety. The solder consists of specific weight percentages: 32.8-56.5% of Bi and 0.7-2.2% of Sb, with the remaining component being Sn. A unique relationship between the weight percentages of Bi and Sb is described by the equation b=0.006a²−0.672a+19.61+c, where 'a' represents the weight percentage of Bi, and 'b' represents that of Sb, with 'c' ranging between -1.85 and 1.85. This solder alloy, possessing a peritectic or near peritectic structure, exhibits a low melting point along with excellent mechanical performance and reliability, making it ideal for low-temperature soldering applications.

Additionally, Zhang has developed an innovative image processing apparatus and method. This technology includes a filter responsible for performing iterative filtering on input images, alongside an iterative filtering stopping device that determines when to halt the filtering process based on the variation speed of the filtered image throughout the iterations. This invention showcases Zhang’s expertise in enhancing image processing capabilities.
