Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a TR component ballasting device and an installation method. Background technique [0002] In China, the microwave field is in a stage of rapid development, and the technical core of its field is still TR components. TR components include TR components including chips, radio frequency microstrips, and capacitors. The electrical properties of TR components are not only related to chip performance and its matching chain. In addition to being closely related to the circuit, it is also related to the alignment accuracy of each device and the eutectic void rate in the packaging process. For high-power TR components, the void rate of chip soldering during the eutectic packaging process will directly affect its life and TR components. Overall performance, at this stage, eutectic welding of TR components often adopts two welding methods: manual tweezers eutectic welding and vacuum eut...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of using vacuum eutectic welding. The operation and calculation parameters are very complicated. Using manual tweezers for eutectic welding can easily generate oxide film, resulting in a large void rate and a lot of oxidized dross, and the device will fail early. The force applied on the chip can easily cause chip chipping, edge chipping, inaccurate alignment, and asynchronous pressure loading. It is difficult to complete the installation of circuit chips and TR components at the same time. The eutectic of multiple TR components is difficult, and the degree of human participation is high. , for the problems of high manual operation requirements, low product yield, slow production speed, and difficulty in mass production, thus providing a TR component ballast device and installation method
