Abstract

A non-contact welding method for the high-temp superconductor microwave filter features that a light beam is emitted from a point light source to a target point to generate a small high-temp area, where the weld material is molten for welding the signal output joint to the filter. Its welder is composed of fixed bench, ponit light source, concave lens, enclosed cavity, convex lens, and location regulator.

Description

(1) Technical field: [0001] The invention relates to a welding method and device for high-temperature superconducting microwave filters, in particular to a non-contact welding method and device for high-temperature superconducting microwave filters. (two) background technology: [0002] For high-temperature superconducting microwave filters, LAO, MGO or LAST ceramic materials with relatively brittle texture are generally used as the dielectric substrate of the filter working sheet, and the thickness is generally about 0.5mm. At the same time, in order to achieve an ideal frequency response characteristic of the filter, especially a very high selectivity, when designing the circuit of the filter, it is generally necessary to adopt a circuit structure of more than ten poles or even dozens of poles, so the electrical performance requirements of the filter At the same time as the increase, the area of ​​the required filter ceramic work piece also becomes larger, which increases ...
