Embodiment Construction

[0021] See image 3 , image 3 Shown is a schematic diagram of the combination of the welding device and the circuit board according to the present invention. The welding device of the present invention is used for welding the first circuit board 11 and the second circuit board 12 that are arranged oppositely. In this embodiment, the first circuit board 11 The second circuit board 12 may be a flexible printed circuit board (FPC). The first circuit board 11 has a solder hole 15, the second circuit board 12 has a solder joint corresponding to the solder hole 15 on a side close to the first circuit board 11, and the solder joint has a second solder 16.

[0022] The soldering device 17 includes a soldering iron 18 and a heating device 19. The soldering iron 18 is used to dip the first solder 20 into the solder hole 15. The heating device 19 is arranged on a side of the second circuit board 12 away from the first circuit board 11 and corresponds to the second solder 16. In addition,...

Abstract

The invention provides a welding device and a welding method. The welding device is used for welding a first circuit board and a second circuit board which are oppositely mounted. The first circuit board is provided with welding holes; the second circuit board, near one side of the circuit board, is provide with welding points corresponding to the welding holes, and the welding points are provided with soldering tins; the welding device comprises an soldering iron and a heating device. The soldering iron is used for dipping the first soldering tin to the welding holes; the heating device isinstalled on one side of the first circuit board which is far from and corresponding to the second circuit board.

Description

Technical field [0001] The invention relates to a welding device and a welding method, and in particular to a welding device and a welding method for liquid crystal display modules. Background technique [0002] With the advancement of science and technology, various electronic products have become an indispensable part of people's lives. Among them, the display is an important component of multimedia electronic products. In the display, there are many components and control signals that need to be controlled. For example, the liquid crystal display panel and the backlight module require different driving signals to drive the liquid crystal molecules of the liquid crystal display panel and the light source in the backlight module. . These driving signals are generally transmitted from the driving unit to the liquid crystal display panel and the backlight module through a circuit board (such as a flexible printed circuit board, FPC) respectively. [0003] At present, in the proce...
