Abstract

The invention provides a filter capacitor assembling method. The filter capacitor assembling method comprises the following steps that blocky capacitors are welded on the upper surface of sheet-shapedcapacitors through soldering irons, and capacitor assemblies are formed; leading-out pins penetrate through the left side and the right side of the lower surface of the filter shell, and welding andfixing are carried out through soldering iron; the filter shell is placed on a heating device to be heated to a certain temperature; a layer of soldering tin is added to the lower surface of the interior of the filter shell, then the capacitor assemblies are clamped and placed on the upper surface of the soldering tin, and then the capacitor assemblies are kept for a certain time and then loosened; the adjacent capacitor assemblies, the capacitor assemblies on the left side and the right side are connected with the lead-out pins through connecting lines, and then soldering tins are added at the joint to carry out welding fixation; when the capacitor assemblies with the far distance are connected, one connecting line is led out of one end of each capacitive assembly, and the connecting lines penetrate through the side face of the filter shell and are uniformly welded; taking down the assembled filter capacitor from the heating device and placing the filter capacitor in air to be cooledto normal temperature.

Description

technical field [0001] The invention relates to the technical field of filter capacitor plates, in particular to an assembly method of filter capacitors. Background technique [0002] In the assembly process of the filter circuit, it is often necessary to use the welding process. Due to the current miniaturization of electronic products, the filter housing is getting smaller and smaller. The ordinary welding process cannot meet the current filter installation, so there is an urgent need for a A new efficient and reliable assembly method for filter capacitors. [0003] For example, the Chinese patent "CN107645849A" discloses a manufacturing method of a microwave-excited high-frequency module. 1) Select a solder paste with a melting point of 217°C and a composition of Sn96.5Ag3Cu0.5, and use a dispenser to spot the solder paste on the component pads on the front of the voltage regulator circuit board; 2) Assemble according to the voltage regulator circuit Figure, place the c...
