With the development of electronic technology, PCB lays a good foundation for a various of electronic products, such as the development of PCB for LED lighting. A prime example is the development of the PCB for LED lighting. The LED is soldered to the circuit board and features a chip that creates the light when electrically connected. A thermal heat sink and a ceramic base are used to bond the chip.
It is difficult for an LED PCB board to cool with traditional methods because it tends to create a high volume of heat. So metal core PCBs are often chosen for LED application as their enhanced ability to dissipate heat. Especially aluminum is often used to fabricate circuit boards for LED lights. The aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.
What is LED PCB?
LED is an acronym for light emitting diode, which is semiconductor diodes. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Needless to say, LED PCB is the core of LED lighting, and an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. So metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum is often used to fabricate PCB for LED lights. In general, the aluminum PCB contains a thin layer pf thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.
Now SMD packaging type is the most widely used packaging form in LED applications. In general, it’s limited for the light emitted from a single LED component. So multiple LED components would be used for a single light fixture to achieve sufficient light. Like other semiconductor devices, PCB is the best method to electrically connect the LED components. And a PCB with LED components soldered is usually called as “ LED PCB ”.
