Composite circuit board device and manufacturing method thereof

Abstract

The invention discloses a composite circuit board device which comprises a hard printed circuit board assembly and a soft printed circuit board for providing a driving signal of a light source, wherein the hard printed circuit board assembly is provided with a bearing section and a connecting section, the light source is arranged on the bearing section, and the connecting section is electrically connected with the contact section of the soft printed circuit board, wherein a positioning hole is formed on the contact section of the soft printed circuit board, and a positioning piece is arranged on the connecting section of the hard printed circuit board assembly. In addition, the soft printed circuit board is provided with at least two bent parts, and the soft printed circuit board is bent at the position of the contact section. By the special structural design of the combining part, the positioning piece of the hard printed circuit board assembly passes through the positioning hole of the soft printed circuit board to be combined and fixed, thus additional element processing programs are not needed, the product cost is lowered, and the manufacturing efficiency is improved.

Description

technical field [0001] The present invention relates to a circuit board fixing device and method; specifically, by combining the circuit board fixing device with the positioning element structure corresponding to the circuit board, the use of adhesive materials is reduced. Background technique [0002] Currently, the market is flooded with a variety of display electronic products, among which liquid crystal display devices are widely used, including LCD TVs, desktop monitors, and notebook computer LCD screens and other related products. [0003] like figure 1 Shown is a schematic diagram of a conventional liquid crystal display device. The display device 1 has a display panel 100 and a backlight module 200. The backlight module 200 includes a light emitting module 210. The light emitting module 210 provides the backlight required by the liquid crystal display panel 100, so that the display device 1 can display full-color images for users to watch. [0004] see Figure 2A ...
