Description

What is LED PCB Board Manufactureing ?

Both LED Aluminium PCB and FR-4 fiberglass circuit board belong to PCB. To say differently, only compare LED aluminium substrate with FR-4 fiberglass circuit board.

LED aluminium substrate is printed on the surface of aluminium material with better thermal conductivity, and then weld electronic components on it.

In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.

The voltage drop across an LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage greatly increases the current.

Very simple circuits are used for low-power indicator LED. More complex, current source circuits are required when driving high-power LEDs for illumination to achieve correct current regulation.

An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means.

PCB LED Applications

PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and

maximum design flexibility. Examples include Automotive headlights, Airport runway landing lights, Lighting used in military field applications,

Street lighting, Highway tunnel lighting, Photovoltaic (solar) lighting, Flashlights and lanterns, Traffic and signal lighting, Lighting in hospital

operating rooms, High growth plant lighting and many others.

About Aluminum PCBs

Most common among metal-core printed circuit boards is the aluminum PCB. This type of printed circuit board is built on top of an aluminum alloy

base, instead of a fiberglass base. The alloy usually consists of a combination of magnesium, aluminum , altering the properties of the

metal to best suit the needs of the application.

Among all Metal core PCB  (aka MC PCB, known for their ability to provide effective thermal dissipation for electronic products), Aluminum PCB is

the most common type- the base material consists of aluminum core with standard FR 4. It features a thermal clad layer that dissipates heat in a highly

efficient manner, while cooling components and increasing the overall performance of the products. Currently,Aluminum Backed PCB is regarded as

the solution to high power and tight tolerance  applications.

All aluminum PCBs consist of the following layers

There is a number of materials used in LED PCB but the primary materials are the following:

  • 1:The Base Layer
  • 2:The Thermal Insulation Layer
  • 3:The Circuit Layer

The Base Layer:

The base layer of the PCB is the aluminum alloy sheet upon which the rest of the PCB builds. This alloy is typically designed to provide maximum electrical insulation and thermal conductivity.

The Thermal Insulation Layer:

This layer is extremely important in the design of the PCB. Consisting of a ceramic polymer, this layer protects the PCB from mechanical or thermal damage by offering thermal resistance and viscoelastic properties. This works by absorbing the heat created as the current moves through the circuits and transferring it to the aluminum layer — there it disperses.

The Circuit Layer:

This layer contributes most to the end function of the board, containing the copper foil circuits needed for the PCB to function.
These layers occur in any number of variations, with one or several thermal and circuit layers depending on the particular application. The layers listed also lend a
number of different benefits to aluminum PCB, which can be of use to several key industries.

Types of Aluminum PCB

There are several Type for the LED PCB.

  • 1:Flexible Aluminum
  • 2:Hybrid Aluminum
  • 3:Multilayer Aluminum
  • 4:Through-Hole Aluminum

Why use LED PCB ?

In a sense, LED PCB and aluminum PCB belong to the same kind of PCB products, because their uses and materials are mostly the same.

With the popularization and widespread use of industrial lighting and civil lighting, whether outdoor or indoor, family or commercial buildings and

factories, lighting provides the guarantee of its normal operation.

Of course, nowadays, with the development of human society, environmental pollution has become a difficult problem in the world. In order to reduce

the consumption of coal, such as coal used for power generation in thermal power plants, coal combustion pollutes the atmosphere very seriously. In

order to save energy and protect the environment, LED lights and previous lighting methods have great advantages, except for energy. Besides

providing brighter lights, it also contributes to environmental protection.
