Positioning tool for miniaturized radio frequency power module eutectic welding and method of use thereof

Abstract

The invention provides positioning tooling for eutectic soldering of miniaturized radio frequency power modules, including: flange limiting tooling; through-rod type pressure limiting tooling, including: a support plate, four corners of the body are processed with embedded limiting holes, and the surface is processed with array rows The through hole of the cloth; the counterweight pressure rod is a two-stage stepped structure, and the counterweight is applied through the through hole on the surface of the support plate; the support column is threaded and installed with the support plate through the embedded limit hole; the bottom plate, Install with the support column through the limit slot. The invention also provides a method for using the positioning tool for the eutectic welding of the miniaturized radio frequency power module. The position of the tooling structure design is accurate and flexible, and the operation is simple. All the operations are controlled by the limit in the process, which can greatly ensure the reliability of the eutectic welding of the RF power printed board.

Description

technical field [0001] The invention relates to the technical field of large-area eutectic welding of printed boards and substrates, in particular to a positioning tool for eutectic welding of miniaturized radio frequency power modules and a use method thereof. Background technique [0002] With the rapid development of modern electronic integration technology, miniaturization, high speed, and high precision have become the development direction of aerospace model applications, and the material requirements and demands of different product design processes have also changed. More and more Types and models of printed boards have entered the aerospace field, including TMM4, TMM6, and flexible boards; at the same time, the thickness, size, and shape of printed boards have also changed accordingly; Demand, the difficulty in designing the assembly process of model products has been greatly increased. After the printing is completed, there is warping and it is difficult to be flat...
