Description

Technical Field

[0001] The utility model relates to the technical field of circuit board fixtures, and in particular to a glass-based Mini LED circuit board fixture. Background Art

[0002] Mini LED circuit boards are the electrical connections for Mini LED backlight modules. As display resolution requirements increase, the spacing between LEDs is shrinking, leading to higher heat dissipation per unit area. Glass substrates offer superior heat dissipation compared to conventional PCB substrates, and their excellent surface flatness further enhances the display quality of fine-pitch LEDs, making them the preferred choice for high-end Mini LED backlight modules.

[0003] When using existing circuit boards, it is easy to damage the circuit boards when transporting glass-based circuit boards of different sizes. At the same time, when using plasma to treat flexible circuit boards, the four sides of the flexible circuit boards are prone to warping during the discharge process, which has a certain impact on the treatment effect. In order to address the shortcomings of the existing technology, we propose a glass-based Mini LED circuit board fixture. Utility Model Content
