7w Bulb Aluminum LED PCB


LED PCB Aluminum smd led pcb board 94v0 3w 5w 7w Bulb Pcb

The first thing we want you to understand is that LED means Light Emitting Diode. It features semiconductor diodes, which when soldered to a Printed Circuit Board (PCB) will create light on the board.


Generally, LED PCB is considered to be a circuit board that has the LED components soldered to it. However, there are other important properties and compositions of the circuit board that we want you to understand too.

For a LED PCB to function effectively, a ceramic base and a thermal heat sink will be used to bond a chip to create light as electrically connected on the circuit board.


Worthy of mention is that manufacturing LED PCB tends to take a different turn, especially when it comes to cooling heat. Because traditional methods aren’t easy to cool the heat on a LED PCB, it became imperative to use the materials that can do the work.
