| 中文摘要: |
| 垂直互连技术具有互连路径短、空间利用率高、速度快等诸多优点，对星载、舰载、弹载等实现微型化、轻量化、多功能化具有重要战略意义。毛纽扣连接器作为一种弹性连接器，常用于低矮化多层印制板间的垂直互连，其自身体积小、微波性能好、工作频段宽、易拆卸、低延迟，且可以有效抑制连接器内部信号的互感效应，减小信号传输的路径长度和高频信号的趋肤效应，在射频微波领域具有重要用途。重点综述了材料类型及电镀金厚度对毛纽扣连接器性能的影响，归纳了通过建立理论模型分析毛纽扣连接器的电学性能及力学本构模型的方法，并揭示了高、低温(‒55~85 ℃)冲击下毛纽扣连接器的可靠性，总结了其在印制电路板和微型连接器中的应用。总体来说，我国对毛纽扣垂直互连技术研究较少，特别是在宇航领域，还需积极地进行技术攻关，确保其在真空、温度交变、辐射及原子氧等苛刻复杂的宇航服役环境中的可靠性。对此，综述了基于毛纽扣连接器的垂直互连技术的基本原理，以及影响毛纽扣性能及可靠性的服役环境，分析了近年来国内外在毛纽扣连接器领域取得的研究进展，并展望了毛纽扣连接器的发展方向，可为基于毛纽扣连接器的垂直互连技术的发展提供有益的参考和启示。 |

| Vertical interconnection technology characterized by advantages, such as short interconnection path, high space utilization rate, high speed, etc., has important strategic significance for miniaturization, light weight and multifunction of space-borne, ship-borne, missile-borne, etc. As an elastic connector, the fuzz button connector is often used for vertical interconnection between low-rise multi-layer printed boards. It has the advantages of small size, good microwave performance, wide working frequency band, easy disassembly and low delay and can effectively restrain the mutual inductance effect of the internal signals of the connector and reduce the path length of signal transmission and skin effect of high-frequency signals, with important application in the field of RF microwave. The effects of material types and thickness of gold plating on the properties of fuzz button connector were summarized, and the methods of analyzing the electrical properties and mechanical constitutive model of fuzz button connector by establishing theoretical models were concluded. In addition, the reliability of fuzz button connector under high and low temperature impact (‒55-85 ℃) was revealed, and its applications in printed circuit boards and miniature connectors were summarized. In general, there was little research on the vertical interconnection technology of fuzz button in China, especially in the aerospace field. It was still necessary to actively tackle key technical problems to ensure the reliability in the harsh and complex service aerospace environment such as vacuum, temperature alternation, radiation and atomic oxygen. Therewith, the basic principle of vertical interconnection technology based on fuzz button connector was reviewed, the service environment that affected the properties and reliability of fuzz button was summed up, the research progress made in the field of fuzz button connector at home and abroad in recent years was analyzed, and the development direction of fuzz button connector was prospected, which could provide useful reference and enlightenment for the development of vertical interconnection technology based on fuzz button connector. |
