Protective printed circuit board

Abstract

The invention relates to the technical field of printed circuit boards, in particular to a protective printed circuit board. The printed circuit board comprises a top layer, a middle layer, a bottom layer, a heat conduction layer, a copper foil circuit and a solder mask layer, wherein the top layer, the middle layer and the bottom layer are fixedly connected through pressing equipment, and the middle layer comprises a heat dissipation layer, an arc isolation layer, an anti-corrosion layer, a flame-retardant layer and an insulating layer; the heat dissipation layer is located in the middle of the middle layer, the arc isolation layers, the anti-corrosion layers, the flame-retardant layers and the insulating layers are sequentially distributed on the upper surface and the lower surface of the heat dissipation layer, the upper surface and the lower surface of the heat dissipation layer are fixedly bonded with one sides of the two arc isolation layers respectively, and the surfaces of thetwo arc isolation layers are fixedly bonded with the surfaces of the two anti-corrosion layers respectively. The purpose of improving the weather resistance of the printed circuit board is achieved, the phenomenon that the PCB is prone to corrosion is avoided, the overall property of the PCB is improved, the service life of the PCB can be prolonged, the use places are wide, and the use requirements of special places can be completely met.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a protective printed circuit board. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. [0003] In the process of using the PCB, the PCB, as the core part of the motherboard, needs to be assembled inside the device. Due to long-term use, outdoors or other complex environments, the PCB will often be corroded due to various conditions. After corrosion The PCB will cause irreparable damage to the entire motherboard, so it is easy to be corroded and has become a very urgent problem restricting the application field of PCB, resulting in the reduction of the service life of the ...

[0003] In the process of using the PCB, the PCB, as the core part of the motherboard, needs to be assembled inside the device. Due to long-term use, outdoors or other complex environments, the PCB will often be corroded due to various conditions. After corrosion The PCB will cause irreparable damage to the entire motherboard, so it is easy to be corroded and has become a very urgent problem that limits the application field of PCB, resulting in the reduction of the service life of the PCB itself and low applicability
