Abstract

The invention relates to a method for fixing LED lamp beads, an LED lamp belt and a mobile terminal, wherein the method for fixing LED lamp beads includes: using an FPC fixture to perform FPC positioning; printing solder paste at a plurality of first designated positions on the upper surface of the FPC; Dot red glue on multiple second designated positions on the upper surface of the FPC after solder paste printing; check whether the printed solder paste meets the requirements through SPI solder paste printing inspection equipment; solder multiple LED lamp beads to the FPC one by one by reflow soldering, And control the welding temperature to 150°C to make the red glue harden after being heated. The LED lamp bead fixing method provided by the present invention increases the process of pointing red glue, and controls the welding temperature to 150°C, so that the red glue can be cured immediately after being heated, so that the LED lamp bead and FPC that were originally only welded together by solder paste , adding red glue bonding, improving the fixing reliability of the LED lamp beads on the LED strip, and improving the anti-push performance of the LED lamp beads.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a method for fixing LED lamp beads, an LED lamp strip and a mobile terminal. Background technique [0002] The backlight (Back Light) is a light source located behind the liquid crystal display (LCD), and its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). Backlight is widely used in touch screen, LCD / LCM, mobile phone, tablet computer, GPS and solar cell and other industries; it is mainly composed of light source, light guide plate, optical module and structural parts; among them, the light source mainly includes EL, CCFL and LED Types of backlight sources; light guide plates are divided into printing, chemical etching (Etching), precision mechanical characterization (V-cut), light lithography (Stamper), internal diffusion, hot pressing; optical modules: enhancement film / sheet, Diffusion film / sheet, reflection sheet, ...
