PCB circuit board

Abstract

The invention discloses a PCB circuit board including a circuit board body, a heat dissipation mechanism and a mounting mechanism, A heat dissipation mechanism is installed at the bottom of the circuit board main body, and mounting mechanisms are installed around the heat dissipation mechanism. The circuit board main body comprises an adhesive layer, an insulation heat conduction layer, a substrate, a wiring layer, a heat dissipation hole, a temperature sensor, a solder green paint, an electronic component, a wire, a nano waterproof coating and a corner groove. As that heat dissipation mechanism and the nano waterproof coat of the invention have the functions of waterproof and heat dissipation, the service life of the circuit board is prolonged; At that same time, the circuit board main body and the heat dissipation mechanism are adhered together when the circuit board main body is installed, and the mount mechanism is installed around the heat dissipation mechanism, so that the circuit board main body is not stressed and will not be damaged because of the installation when the circuit board main body is installed; At that same time, the mount mechanism can effectively alleviate the absorption collision and play a protective role when the mounting mechanism is subject to large collision.

Description

technical field [0001] The invention relates to the field of PCB circuit boards, in particular to a PCB circuit board. Background technique [0002] PCB circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and Assembly errors have improved the automation level and production labor rate; printed circuit boards, also known as printed circuit boards, printed circuit boards, or printed boards for short, use insulating boards as the base material, cut to a certain size, and have at least A conductive pattern with holes (such as component holes, fastening holes, metallized holes, etc.), used to replace the chassis of electronic components installed in the past, and to realize the interconnection between electronic components, because this board is It ...

AI Technical Summary

Problems solved by technology

[0003] The waterproof and heat dissipation functions of the existing PCB circuit boards are poor, and the PCB circuit boards are often damaged and cannot be used due to the accumulation of water and heat that cannot be dissipated. The mounting hole is fixed on the mounting surface, but the PCB circuit board is often damaged due to uneven force on the mounting hole. At the same time, the PCB circuit board is easily damaged in collision and vibration because there are a large number of electronic components installed on the top of it.
