12W SMD 2835 Aluminum LED PCB 94v0 Emergency Light Circuit Board

SMD stands for Surface Mount Device. The surface mount technology (SMT) has almost replaced the through-hole technology. However, through-hole technology is still used for the components that cannot be surface mounted. Therefore, Surface Mount LED PCB is very popular

SMDs are compact components that can be directly placed over the PCB. There is no need for a hole because the components do not have leads or might have small leads. There are only small contacts at the ends of the device that are used to make connections. Consequently, the PCBA is very compact. SMDs are soldered using reflow soldering. At first, the solder paste is applied on the bare board. Then, the components are picked and placed in the desired place. Finally, the board is passed through a reflow oven, and the components are directly mounted without any hassle.

An SMD LED PCB board contains SMD LEDs that are more compact than their through-hole equivalents. SMD LEDs are widely used nowadays. They provide higher lumen output, which improves the level of illuminance in the area. They are more efficient and brighter. This is the reason SMD LED PCB boards are preferred.
