The research progress and direction of the key technology of the T / R module of the active phased array system are analyzed. Its purpose is to reduce the cost of mass production and improve the performance and reliability. It is discussed from the following aspects: in terms of the core components, MMIC has always been the key component of t / R, and its development trend is to customize low-cost, multi-functional integrated chips according to the system requirements; in terms of the structural form, With the continuous        development of miniaturization, brick T / R modules are more commonly used, but tile T / R modules have a wide application prospect; in terms of packaging technology, LTCC or HTCC co fired ceramic, silicon-based 3D integrated packaging technology and other technologies coexist; in terms of high-density interconnection, micro connectors, fuzz buttons, etc.; in terms of thermal management, ain, diamond copper, phase change energy storage and other new materials, In the aspect of manufacturing mode, from manual micro assembly to intelligent micro assembly line. The innovation and development of T / R components support the continuous upgrading of phased array system, which is the only way to improve the capability of integrated electronic system.

       Floss Pin®（i.e. Fuzz Button or CIN::APSE） is a patent product of Luoyang Fuzz button Interconnect Technology Co.,Ltd.  It is the most reliable and advanced welding compression-style interconnect technology。It provides the board-to-board advantages for high-speed telecom，stringent military and aerospace，and demanding automotive applications。

      It is the ideal interconnect solution for vertical interconnection of the microwave module，Ideally suited for applications in which high reliability，high-speed signals，tight envelope dimensions，high density，and extreme environmental conditions need to be met。

      We are the first company successfully developed and mass production the Fuzz Button® or CIN::APSE® in the China。The product performance is leading inChina, and the key parameters have reached the level of similar products such as fuzz buttons®  from Custom Interconnects in theUSA.
