Description

Technical Field

[0001] The utility model belongs to the technical field of microwave component SMP welding, and in particular relates to an integrated welding tool for a multi-channel SMP connector. Background Art

[0002] In phased array radar systems, SMP connectors are widely used to connect antenna units and RF circuits, enabling signal transmission and control. For example, they are widely used in automotive and airborne phased array radars. Their extremely small size provides a suitable connection method for highly sealed phased array radars, facilitating easier assembly, testing, and management of the units.

[0003] At present, phased array radars need to assemble more SMP connectors with a larger number of channels to the corresponding positions of structural parts at one time during production and assembly. This requires a high level of technical skills from the operators. During the process of welding SMP connectors to structural parts, operators need to use tweezers on the heating table to grasp the welding conditions of each SMP in turn and observe with the naked eye whether the SMP connectors are assembled in place. At the same time, they need to manually control the welding pressure and welding time. Larger welding pressure and longer welding time can easily cause damage to the base material of the SMP connector or microwave component and oxidation of the solder. Therefore, the shortcomings of the current traditional manual welding method can be summarized as: time-consuming welding, low efficiency, low one-time welding pass rate, poor consistency, and high scrap rate. Therefore, we need to upgrade and transform based on existing technologies. Utility Model Content
