Technical Field

[0002] Metal and glass have been widely used as a material combination in microelectromechanical systems (MEMS) packaging applications. In many MEMS applications, metal is found to be the main substrate material due to its unique electrical, thermal and mechanical properties. In addition, circuits can be easily mass-produced on metal surfaces by photolithography, and they can be used as microelectronic circuits such as sensor and actuator applications. On the other hand, glass is very popular in MEMS packaging applications due to its excellent mechanical properties, chemical stability, good electrical insulation and optical transparency, and has been used to cover electronic microcircuits as protection in sensor applications.

[0003] In micro-machining technology, many technologies have been selected as processes for connecting metal and glass. There have been reports on the use of epoxy resin to connect metal and glass, but its connection performance is easily changed with the ambient humidity and temperature. Therefore, it is necessary to use a welding test device to test the connection performance according to time, ambient humidity and temperature. However, most existing welding test devices lack protective mechanisms, and workers perform inspections in open-air environments. The large amount of heat and light generated by the welding test device can easily cause harm to the workers, and the positioning mechanism of the welding test device is mostly located at the bottom of the welding mechanism, which poses certain safety risks to workers when loading and unloading metal and glass.

[0004] Therefore, most of the above-mentioned existing welding test devices lack protective mechanisms, and the large amount of heat and light generated by the welding test devices can easily cause harm to the workers, posing certain safety hazards. Therefore, a metal and glass laser micro-welding test device can be designed. The protective cover door can be pulled out by the placement seat to move up and down on the inner side of the device shell, which is convenient for the workers to load and unload metal and glass. When the protective cover door is closed, the workers are protected by the protective cover door, and a light-shielding layer is provided on the surface of the protective cover door to shield the light generated by the welding mechanism, which is convenient for the workers to better observe the welding test.
