[0040] The positioning and welding tool provided by the present application will be described in detail below. Specifically, the positioning and welding tool comprises a tray 10, a base 20 and an array cover plate 60. A first limiting groove 103 is formed in the surface of the tray 10 and used for placing the base 20 and limiting the base 20. An emptying groove 102 penetrating the surface of the tray 10 is formed in the surface of the first limiting groove 103 and used for embedding a tin-spraying opening of the welding device.

[0041] A second limiting groove 203 is formed in the surface of the base 20 and used for placing an antenna array composed of a power division network circuit board 11 and a plurality of vibrator assemblies. The groove wall of the second limiting groove 203 can limit the front, back, left and right of the power division network circuit board 11, and can effectively prevent the power division network circuit board 11 from being deviated on the base 20.

The array cover plate 60 is used for being pressed above the vibrator assemblies and being detachably fixedly connected with the base 20.

[0043] Preferably, the through hole 202 is a circular through groove structure, which is used for exposing all the welding point positions of the power division network circuit board 11 after the vibrator assemblies are inserted into the power division network circuit board 11, so as to spray and weld the welding points on the bottom surface of the power division network circuit board 11.
