Solar lamp, PCB used for solar lamp and manufacturing method thereof

Abstract

An embodiment of the invention provides a solar lamp, a PCB used for the solar lamp and a manufacturing method thereof. At least one gap groove is arranged on the PCB, two sides of the gap groove are provided with bonding pads, the bonding pads are connected with an internal circuit of the PCB, and two pins of a plug-in type electronic component are welded to the bonding pads at the two sides of the gap groove. Through the gap groove on the PCB, automatic welding of the plug-in type electronic component on the PCB can be realized by adoption of an automatic surface-mounting process. The abovementioned technical scheme adopts the plug-in type electronic component which is relatively low in cost, and also adopts the automatic surface-mounting process, thereby realizing improvement of production efficiency and product quality while saving cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of printed circuit boards, in particular to a solar lamp, a PCB circuit board used for the solar lamp and a manufacturing method thereof. Background technique [0002] Solar lights are composed of solar cell components (solar crystal panels), ultra-bright LED lights (light sources), maintenance-free rechargeable batteries, automatic control circuits (PCB circuit boards), and lamps. Mainly use the energy of solar cells to work. When the sun shines on the solar cells during the day, the light energy is converted into electrical energy and stored in the battery, and then the battery provides power for the LED (light-emitting diode) of the lawn lamp at night. . Its advantages are mainly safety, energy saving, convenience, environmental protection, etc. It is suitable for beautifying lighting embellishment of green grass in residential communities and beautifying lawns of parks.

AI Technical Summary

Problems solved by technology

[0004] When automatic placement is used, although the production efficiency is improved, the cost of producing SMD electronic components is relatively high, and in some specific cases, such as when the electronic components have large specifications or meet the needs of PCB circuit layout, it cannot be used. Automatic patch technology, can only be installed by traditional plug-in method

In the case of plug-in installation, although the cost of producing plug-in components is low, the installation requires labor, which increases the cost of the product, and easily leads to the risk of uneven installation of electronic components and short-circuiting of pins
