The invention discloses an airtight high-reliability packaging method for an optical fiber and a shell, which is different from the traditional processes of glue sealing, solder melt sealing and the like, performs matching design on materials, processes and structures of the optical fiber and the shell, realizes airtight packaging of the optical fiber and the shell through a six-degree-of-freedom laser melt sealing technology, and performs reliability evaluation. According to the invention, airtight packaging of the optical fiber and other cables and the tube shell can be realized, and the method can be widely applied to airtight high-reliability packaging of products with cables, such as high-quality-grade photoelectric modules. Derived products such as photoelectric modules with high air tightness and reliability have very wide application prospects in the aspects of optical fiber communication, high-speed data transmission and the like.

The invention provides an airtight high-heat-conduction photoelectric module shell and a manufacturing method. The airtight high-heat-conduction photoelectric module shell comprises a shell body. The shell body is made of silicon-aluminum alloy; a heat conduction boss is arranged in the shell body and is used for placing a power device and a chip; a plurality of leads are arranged on the two sides of the shell body, and insulators are arranged at the connecting parts of the leads and the shell body; the side wall of the housing body is provided with an optical fiber sealing tail tube. Airtight packaging is achieved through the laser sealing and welding technology, and the method can be widely applied to airtight packaging of products such as high-quality-grade photoelectric modules. The high-silicon aluminum alloy is used as the base material of the shell, so that the shell has the remarkable advantages of light weight, high heat conductivity, high strength, high long-term reliability and ...
