Problems solved by technology
The size of the PCB board is directly related to the number of electronic components and electronic circuits installed on the PCB, as well as the number of LED light-emitting diodes installed. When the area of the PCB board is too large, it will appear very bulky, affecting the application of LED lighting. and installation inconvenience
[0003] In the prior art, the PCB board is generally installed in a specific LED product, and is connected to the installation medium through the specific product; the PCB board in the prior art does not have a fixing device, and there is no direct connection between the PCB board and the installation medium , the connection between the PCB board and the installation medium is not stable enough, and it is easy to damage the PCB board and the devices mounted on the PCB board due to various shocks or man-made collisions.

Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as figure 1 As shown, it is a 3-layer PCB composite board of the present invention, and the 3-layer PCB composite board is composed of a double-sided PCB board 101 and a single-sided PCB board 103 . The upper and lower surfaces of the double-sided PCB plate 101 are provided with a conductive pattern layer, and electronic components and electronic circuits are printed on the conductive pattern layer, which are used to make the LED light-emitting diodes installed on the PCB board work normally; the single-sided PCB plate 103 The side opposite to the double-sided PCB block 101 , that is, the upper surface is provided with a conductive pattern layer. The double-sided PCB board 101 and the single-sided PCB board 103 are stacked and pressed through the insulating adhesive sheet 102, and then formed into a whole 3-layer PCB composite bo...

The invention discloses a PCB composite board with a fixing device. The PCB composite board has 3 to 10 layers, wherein each layer of the PCB comprises an insulating substrate and a conductive pattern layer printed on the insulating substrate; and in addition, the PCB composite board is provided with at least one fixing device for fixing and installing the PCB composite board. When a plurality of electronic elements and electronic circuits are mounted on the PCB composite board, the PCB composite board can occupy the smallest space; and the PCB composite board is directly fixed in an installing medium by the fixing device, so the stability of the PCB composite board and the installing medium is improved and the PCB composite board is not easy to damage.
Description
technical field [0001] The invention relates to a PCB board, in particular to a PCB composite board of a fixing device. Background technique [0002] In the LED industry, the PCB board is not only used as the carrier of the light source, but also as the mounting substrate for other devices, such as capacitors, resistors, control / constant current chips, and triodes. In the prior art, the PCB boards used in the LED industry are all single-layer PCB boards or double-layer PCB boards, that is, conductive pattern layers are printed on one surface (single layer) or two surfaces (double layer) of an insulating substrate , and then install LED light-emitting diodes and other devices on a single-layer PCB board or a double-layer PCB board. The size of the PCB board is directly related to the number of electronic components and electronic circuits installed on the PCB, as well as the number of LED light-emitting diodes installed. When the area of the PCB board is too large, it will...
