Problems solved by technology

[0004] In the PCBA assembly method provided by the prior art, because the IPM module is first locked with the heat sink, and then the IPM module is inserted on the PCB board, it is easy to cause visual interference due to the large volume of the heat sink compared with the IPM module, and affect the pins of the IPM module. Docking with the socket on the PCB board; because the wave soldering of the IPM module is performed first, and then the PCB board and the heat sink are locked, the IPM is easily affected by the wave impact during the wave soldering process, resulting in the IPM module after soldering The floating height makes it difficult to guarantee the installation consistency of the IPM module; at the same time, due to the floating height of the IPM module, the screw fixing force will be unbalanced when the radiator is locked, and there is a greater risk of stress, which reduces the PCBA components. safety and reliability of use

Abstract

The invention belongs to the technical field of liquid crystal display, and particularly discloses a PCBA assembly assembling method, an assembling jig and a PCBA assembly. The assembling method comprises the steps of providing a PCB, a radiator and an IPM module; arranging the IPM module on the PCB in an inserted mode; pressing the radiator on the side, which is away from the PCB, of the IPM module; locking the PCB and the radiator by adopting a first locking screw; locking the radiator and the IPM module by adopting a second locking screw; and welding the IPM module and the PCB. The assembling jig is applied to the PCBA assembly assembling method, and the PCBA assembly is formed by adopting the PCBA assembly assembling method. According to the PCBA assembly assembling method, the assembling jig and the PCBA assembly provided by the invention, the assembling efficiency of the PCBA assembly can be improved, and the stress risk after the PCBA assembly is assembled is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an assembly method of a PCBA assembly, an assembly jig and a PCBA assembly. Background technique [0002] With the continuous development of liquid crystal technology, liquid crystal display devices are widely used in fields such as computers, mobile phones, and televisions due to their advantages such as clear image display, no flicker, light weight, thin thickness, and low power consumption. [0003] In order to control and dissipate heat from the liquid crystal display device, the liquid crystal display device is usually provided with a PCBA assembly composed of components such as a PCB board, an IPM module, and a heat sink. When the existing PCBA components are soldered and assembled, the IPM module is first locked with the radiator, and then the IPM module is inserted on the PCB board, and then wave soldering is used to pass the IPM module through the pins on ...
