technical field [0001] The invention relates to the technical field of electric mosquito swatters, in particular to a control circuit board for electric mosquito swatters and a production process thereof. Background technique [0002] The existing control circuit board for electric mosquito swatters includes electronic components and a PCB board provided with circuits. The electronic components are all plug-ins with pins. When soldering the PCB board, it is necessary to insert the pins of the electronic components into the pin holes, and then solder and fix them. The control circuit board with this structure can be realized through two production processes: the first one is manual welding, which has the disadvantages of low work efficiency, unstable quality, and requires a large number of workers, and it is easy to cause problems during welding due to unskilled operation.

Problems solved by technology

The control circuit board with this structure can be realized through two production processes: the first one is manual welding, which has the disadvantages of low work efficiency, unstable quality, and requires a large number of workers, and it is easy to cause problems during welding due to unskilled operation. False welding, or the electronic components are affected by the welding time is too long; the second type, mechanical welding, because the pins of the electronic components are easily deformed, when the plug-in (electronic component) is mechanically placed, the plug-in is deformed due to the deformation of the pins of the electronic component. If it is not correctly inserted on the PCB board, the repair rate will be greatly increased, resulting in a decrease in production efficiency and an increase in cost, which can be said to be time-consuming and laborious

[0003] In addition, since the electronic components are plug-ins with pins, they are large in size and heavy in weight, and they need to be placed on the PCB board with tweezers, so when laying out the circuit on the PCB board, it is necessary to reserve sufficient space, resulting in an increase in the volume of the control circuit board. Large, which limits the design of the electric mosquito swatter

Moreover, the area of ​​solder joints on the PCB is large, resulting in a large increase in the amount of solder, which further increases the cost of the product

[0004] In addition, because the electronic components of the control circuit board for electric mosquito swatters are plug-ins with pins at present, the control circuit board takes up a large space in the handle of the electric mosquito swatter, so that there is not enough space in the handle of the electric mosquito swatter. The heat dissipation of the control circuit board reduces the life of the control circuit board

Especially for electric mosquito swatters that also have functions such as charging and lighting, the control circuit board is larger, and its working heat is more difficult to dissipate, which greatly reduces the service life of electric mosquito swatters
