Technique for detecting the adhesion quality of PI film bonded on solar array battery substrates

  • 摘要: 航天器太阳电池阵电池基板上PI薄膜的黏结质量直接影响基板工作寿命。为有效、迅速、准确地检测PI薄膜黏结质量,通过热循环和热真空等环境试验,对PI薄膜黏结后微观尺度、非显性化的脱黏、气泡和凸起等典型缺陷进行充分暴露;利用基于偏振成像技术的视觉检测方法,对制备的4组试验样件进行正交试验,准确识别出PI薄膜黏结区域的典型缺陷及其具体尺寸范围。试验结果表明该技术对PI薄膜黏结质量缺陷的检测效果良好。

     

    Abstract: The bonding quality of polyimide (PI) films on the solar array battery substrate of spacecraft directly affects the working life of the substrate. To effectively, quickly, and accurately detect the bonding quality of PI films, the typical defects on PI films such as microscale and non-explicit debonding, bubbles, and protrusions were identified by thermal cycling and thermal vacuum environmental tests. A visual inspection method based on polarization imaging technology was utilized to conduct orthogonal experiments on four sets of prepared samples, by which the typical defects and their specific demensions on bonding areas of PI films were recognized accurately. The experimental results indicate that the technique is effective in detecting the bonding defects of PI films.
