SAMSUNG SMD LEDs in your PCB

There are many devices including LEDs on a PCB using surface mounted components. If the wires are quite thin, through hole components can bend slightly so that it looks cheap from the outside. If making it right to solder the SAMSUNG SMD LED, it will be rigid on the board. What’s more, it can also place the SAMSUNG SMD LED behind a screen, and cheaper LED that use a bulb will stick out through the packaging. So it can place the SAMSUNG SMD LED behind a small screen in your packaging to be cleaner for your device. As you know, many PCBs that contain LEDs are fabricated with multilayer FR-4 substrates, so you need to have a pattern of closely-spaced filled or plated through vias under each component so that it can transmit heat, as well as get to your power and ground layers. 

 If your LEDs have a small footprint and are surfaced mounted, it can use our vias. Probably there will be a weak solder joint or even tombstoning because it doesn’t fill or plate over the vias and then solder can wick into the vias during assembly, so the reason why it’s better to just use SAMSUNG SMD LEDs on an LED lighting array is that the problem with wicking. A single LED with decent power output will not lead to damaging to your board because of undue thermal. However, if you are going to have a system for lighting applications, it will need to suffer from a massive heat for the board that supports your LEDs, and make it hard to cool with traditional methods for the boards. Because the individual SAMSUNG LEDs are too small, you can’t really attach a heatsink anywhere, and a heatsink will block the emitted light anyways. Because there is a great demand on thermal, the boards with a metal core are usually used in LED lighting applications due to their ability to dissipate a great deal of heat. In general, aluminum is used for LED lighting applications as the metal core in PCB. What’s more, aluminum is the most metal used as the core among all the possible metal core PCBs. As well as copper and iron are used for metal core PCBs. 

The advantages of LED PCB

With the electronic products is more and more smaller and thinner, making it popular to use LED PCB, and there are various advantages with using SAMSUNG LED PCB as follows:

· Lightweight, low profile

· dimensional stability 

· thermal expansion 

· heat dissipation

· Lower cost backlit membrane switch

· Dust and moisture resistant

· Make it easy to integrate into complex interface assemblies

· Efficient low power consumption

· Available in a wide variety of sizes, colors, and intensities

· May be used in silver flex membrane switches and copper flex membrane switches.

There are two main reasons which make the SAMSUNG LED PCB be popular in addition to increasing the light output of the fixture with integrating multiple SAMSUNG LED components. 

1. It’s easy to tune the color function by integrating the LED components with different color temperatures or different colors into the same PCB. 

2. It can achieve the various light fixtures to meet different lighting requirements with the boards that have different shapes, sizes and materials.
