Abstract

The invention discloses a vacuum-ultrasonic composite brazing device. The vacuum-ultrasonic composite brazing device comprises a vacuum assembly, an ultrasonic brazing assembly, a computer numerical control (CNC)motion assembly, a heating assembly and a controller, wherein the vacuum assembly comprises a vacuum cover, the CNC motion assembly is connected with the top face of the interior of the vacuum cover, the ultrasonic brazing assembly is connected with the CNC motion assembly, the heating assembly is connected with the bottom face in the vacuum cover, and the controller is connected with the vacuum assembly, the CNC motion assembly, the heating assembly and the ultrasonic brazing assembly. The invention further discloses a brazing method using the method. The vacuum-ultrasonic composite brazing device and method have the beneficial effects that through the ultrasonic degassing effect of the ultrasonic brazing assembly and the vacuum negative pressure in the vacuum cover, high-brazing-penetration-rate and high-strength connection of a microstrip plate on aluminum alloys is efficiently completed under the working condition that scaling powder is not used for the microstrip plate, and high-efficiency, high-reliability and low-cost connection of the microstrip plate on a microwave assembly is realized.

Description

technical field [0001] The invention relates to the field of microstrip plate welding, in particular to a vacuum-ultrasonic composite brazing device and method for large-area microstrip plate welding. Background technique [0002] With the increasing demand for miniaturization, light weight, and high integration of modern electronic equipment, microstrip boards are widely used in high-integration assembly of microwave electronic functional components in aerospace products due to their small size and light weight. In the existing assembly technology of microstrip board and metal shell, screw connection and conductive adhesive bonding are commonly used connection methods, but these two connection methods often cannot meet the requirements of aerospace products in terms of weight, electrical signal transmission and long-term reliability. High index requirements in various aspects. Therefore, the method of brazing is often adopted to realize the large-area grounding connection ...
