Publish Date:2020-11-06

The utility model relates to the technical field of PCB board, particularly to a low-cost PCB assembly with convenient assembly.
Background technology:
PCB board, also known as the printed circuit board, is the electrical connection of electronic components. The main advantage of using the circuit board is to greatly reduce wiring and assembly errors and improve automation and production labor rate. At present, according to the number of PCB layers, PCB can be divided into a single panel, double-sided board, four-layer board, six-layer board, and other multilayer circuit boards.
The PCB board structure is generally composed of a substrate layer and a conductive layer above the substrate layer, and the substrate layer is an insulating layer. In applying the PCB board, the corresponding electronic components will be welded on the electronic component pad on the PCB board’s conductive layer. In the existing technology, the connection between electronic components and the conductive layer is mostly by welding, which has the defects of a cumbersome process, inconvenient assembly, and high production cost. Moreover, the pins of electronic components are fixed on the pad by soldering tin. There may be false soldering.
Also, due to the poor thermal conductivity of the resin composite material of the insulating layer, the heat generated by the work of electronic components is mainly transmitted to the external air through the conductive layer’s copper foil. However, the thickness of the copper foil is minimal, and the thermal conductivity is limited. Therefore, it is usually necessary to set a heat dissipation layer at the insulation layer’s bottom. In the existing technology, the heat dissipation layer is generally connected with. However, these methods have the defects of inconvenient assembly.
