Abstract

The invention relates to a positioning and fixing tool and method for welding a fuzz button connector to a printed board, and belongs to the technical field of printed board assembly. The positioning and fixing tool is composed of a fixing frame, a hexagonal stud and a screw. The special welding positioning and fixing tool is positioned by utilizing a thread penetrating hole in the printed board, and positioning of a fuzz button device in three directions of X, Y and Z during welding is realized by limiting the relative position between the elastic pin inserting end of the fuzz button and the printed board. According to the welding positioning and fixing method, the positioning of the fuzz button by means of manual experience in the welding process of the fuzz button is converted into the positioning through the tool, so that the positioning precision of the fuzz button during welding is improved, and the dependence on the manual experience is avoided.

Description

technical field [0001] The invention belongs to the technical field of printed board assembly, in particular to a positioning and fixing tool and method for welding a button connector on a printed board. Background technique [0002] The digital transceiver sub-array is the core component of the radar front-end. The sub-array adopts a tile-type transceiver integration method. Through a layered design, the radio frequency unit, radiation unit, and control unit are arranged on parallel tiles, and three-dimensional interconnection is used to realize inter-layer signals. The button connector is the core component to realize the electrical and signal connection between layers. One end of the button connector is a soldering pin, which is connected to the upper printed board by through-hole welding, and the other end is an elastic pin with a certain amount of compression, relying on its own elasticity to make the pin end and the lower printed board The pads make direct contact con...
