LED PCB -The Most Useful Introduction

LED PCB -The Most Useful Introduction

Abstract

The evolution in PCB technology has brought the world to re-innovate the application of circuits. Especially in the field on Light Emitting Diodes LEDs. The LED is the device that emits light rays in the visible region upon giving voltage at its terminals. The LED has positive (anode) and negative (cathode) polarities. The LEDs are soldered on the PCB and applied electrical interconnection to illuminate. The heat produced by this LED PCB is so great. That it requires the ceramic based and thermal sink to dissipate heat.

1.What is LED PCB

 

The aluminum is commonly used in manufacturing circuit board for LED lights. It based PCB/PWB has the thermal conductive thin layer of dielectric material that can efficiently dissipate heat as compared to traditional rigid PCBs.

2.LED PCB Applications

 

Due to their combination of excellent energy efficiency, low cost and maximum design flexibility. There are many applications of LED lights PCB including traditional home appliances like LED Lights, Automobile lights, emergency lights, and solar-powered street LED lights, flashlights and LED torch. Copper alloy or CEM3 PCBs are used instead of the standard FR4 substrate due to their high heat dissipation property.

 

3.The aluminum base

 

The aluminum base with thermal conductive dielectric layer will perform as the conducive link between IC and heat sink. Unlike FR4. The copper and aluminum have improved thermal expansion characteristic. The dimensional stability of metallic base PCB is more than FR4 insulating material.

4.Types of Aluminum

 

 4.1 Flexible Aluminum

 

Polymide resins are used with ceramic fillers to provide great insulation and flexibility while maintaining aluminum thermal conductivity.

4.2 Hybrid Aluminum

 

A non-thermal material merged with aluminum metal makes hybrid aluminum. The non-thermal material here is FR4. It provides rigidity while maintaining aluminum super thermal conductivity.

 

4.3 Multi-layer Aluminum

 

In high complex PCBs the multi-layer aluminum provides great thermal conductivity and excellent heat transfer. The advantage of LED lights PCBs is low power consumption, free of mercury, high efficiency, compact and long life.

 

5.LED PCB Service

 

As a PCB manufacturer company, we can provide LED PCB service as well. Enriched by our vast industrial experience in this business. We are involved in offering an enormous quality range of PCB LED Strip Service. But it should see the specific requirements.
