SMD LEDs and SMD LED Chips: what they are and their meaning
SMD LEDs are the acronyms for the English expressions Light Emitting Diode and Surface Mount Device. The association of these acronyms indicates the electronic components made up of LED modules that are mounted directly on one side of the printed circuit through surface mounting technology, called SMT.
SMD LEDs are characterized by a parallelepiped shape, called a chip, containing the emitting surface inside. On the sides, however, there are the diodes that allow the device to be powered.
Soldering SMD LEDs: how to do it?
SMD LED chips are self-contained LED devices that are mounted to the surface of the printed circuit board (PCB) by soldering, using SMT technology. This practice allows you to solder the SMD LEDs on both faces of the circuit, without engravings or drilling being applied to the board.
The advantages deriving from the use of this type of component assembly are:
· the possibility of using smaller components and creating more compact electronic boards ;
· the reduction of the production of waste resulting from the circuit drilling operation;
· A consequent reduction in work times, as a series of automated machinery is used, including the Pick Place machine.

Types of SMD LEDs: all the ones you need to know
There are different types of SMD LEDs, each variant is identified by means of a series of numbers which define its size and associated brightness level. The LED identification number corresponds to the dimensions, expressed in millimeters, of the chip itself.
As regards the main types of SMD LEDs, the most widespread on the market is the 3528. It is one of the first LEDs to appear on the market and is characterized by a power of between 6 and 8 lumens, a consumption of 0.20W, and a somewhat reduced light output.
The 5050 SMD LEDs guarantee a power of between 16 and 22 lumens. They are among the first chips capable of generating greater power and, therefore, are suitable for general lighting needs.
The 5630 and 5730 SMD LEDs were recently developed, they guarantee good brightness with limited consumption and, for this reason, they are very widespread. These are SMD LED diodes suitable for use where high lumens are required.
Finally, the 2835 and 3014 outdoor SMD screen are identified as the devices with the longest life and best performance, thanks to the presence of the heat sink inside them which prevents the source from overheating. This type is usually used on LED strips with both lighting and purely decorative function.
