Description

Technical Field

[0002] The alloy solder cap (fusion seal) is a way to achieve sealing for high-reliability cavity packaging, with excellent structural performance and salt spray resistance, and is widely used in the fields of aerospace, etc. Common solders include gold-tin, etc. The implementation process is as follows: in a clean environment, align the shell and the cover plate (with solder), use a weight or a clip to make the cover plate and the shell in close contact, place them in a capping device and fill it with a protective gas. After heating up, the solder melts, and under the action of the weight or the clip, the solder is extruded and fully wets the shell and the cover plate. After cooling down, the solidified solder firmly adheres the cover plate and the shell together to complete the isolation between the inside of the cavity and the outside atmosphere.

[0003] The assembly of the alloy solder cap is usually carried out manually. Stack the shell and the cover plate (with solder) from bottom to top and fix them with a clip. Incorrect alignment may lead to misalignment of the shell and the cover plate after welding, solder flowing into the inner cavity of the shell, uneven dispersion of the solder, etc.; if the clamping force is not perpendicular to the surface of the cover plate, there may be a situation where the cover plate warps after fusion sealing, resulting in final sealing failure, etc.; the assembly process of the alloy solder cap has high skill requirements, and the cover plate coating may be scratched during the clamping process, resulting in unqualified appearance inspection and a decrease in the corrosion resistance of the cover plate. Therefore, it is necessary to develop an inverted self-leveling clamping structure applicable to the alloy solder cap. Content of the Utility Model
