　　What are the advantages and characteristics of using SMD LED beads? SMT LED is attached to the surface of circuit boards, suitable for SMT processing, and can be reflow soldered. SMT LED effectively handles issues such as brightness, viewing angle, flatness, reliability, and consistency. Compared to other packaging equipment, it has advantages such as strong vibration resistance, low solder defect rate, and good high-frequency characteristics. It encapsulates more LED chips on a smaller area, using lighter PCB and reflective layer data, The reflective layer requires less epoxy resin to be filled.

　　By removing the heavier carbon steel data pins and reducing the size, the product weight can be easily reduced by half. The volume and weight are only about 1/10 of traditional plug-in components. After using SMD packaging, the volume of electronic products is reduced by 40-60%, and the weight is reduced by 60-80%, making use more perfect. The following characteristics:

　　1. The principle of luminescence belongs to cold luminescence, rather than luminescence through heating or discharge, so the lifespan of the component is about 50-100 times longer than that of a tungsten filament bulb, which is about 100000 hours.

　　2. No warm-up time is required, and the response time for lighting is faster than that of ordinary electric lights (about 3~400ns).

　　3. High electro-optic conversion efficiency, low power consumption, saving about 1/3 to 1/20 of energy consumption compared to light bulbs.

　　4. Excellent shock resistance, high reliability, and low system operating cost.

　　5. Easy to compact, thin, lightweight, no shape restrictions, easy to make into various uses.
