How Do SMD Leds Work? How to Use It and What Distinguishes SMD from COB Led
Using through hole components can be tiring especially when components need repeated mounting/dismounting such as LEDs and capacitors. This is where surface mounted technology (SMT) comes in handy. A surface mounted device (SMD) can be easily secured on any PCB by the means of solder. This tech is becoming the industry standard and has largely replaced the through hole technology. There is a variety of SMDs that are in prevalent use but in this article, we are most interested in SMD LEDs, their testing, application and difference between them and COB LEDs. What is a SMD LED? Surface-Mount Device, Light-Emitting Diode, or SMD LED , is a category of LED that is distinguished by having a 3 in 1 encapsulation, or integrating all three colours (Red, Green, and Blue) in a single system. SMD LEDs are currently the most used type of LED on the market. The large-scale production of manufacturers has made it the cheapest kind of LED available in the market at the moment.
