Industrial Applications of LED PCB Boards
The LED PCBs used in the lighting have several advantages over the normal lighting bulbs. They use much less energy for the lighting purposes. Moreover, they are of the small size than those of the normal bulbs. They are environment friendly and don’t need much severe conditions.
They can save up to 80% of the energy as compared to the normal lighting bulbs. On the other hand, they have the stand time that is 25 times greater than those of normal lighting bulbs. Therefore, they have popular and tremendous usage in the lighting purposes.
In this article, you will find necessary information about the LED PCB assembly and their properties. Moreover, it will also illustrate the LED PCB assembly machine cost.
What are LED PCBs?
LED is the abbreviation of light emitting diode. They have the popular use in the lighting purposes in many different industries. LEDs are the electrical components that utilize the semiconductors to convert the electrical energy into light energy.
Printed circuit boards (PCBs) have provided the strength and support to the light emitting diodes. They have produced the value and support for the LED technology. The printed circuit boards have the fibre glass or plastic material in the construction and connect various components.
Therefore, printed circuit boards have become the crucial part of the LED technology. They provide the physical support to the LEDs. They help in the transfer of energy away from the LED bulbs. Moreover, they enhance their performance and save them from being damaged.
On the base of application of the PCBs, they come in variety of the designs and forms. There are different types of the materials for the construction of LED PCBs. LED PCB assembly machine cost is also an important factor that is worth mentioning in the construction process.
The most important thing in the construction of PCB assembly is the material used for the core of PCB. The material used in the core determines the properties of the PCB assembly. The common and frequent materials used in the core of PCBs are as follows:
FR-4 has the tremendous use as a core material. It contains the glass and epoxy in the constitution. The prominent feature of FR-4 is that it has the retarding feature against the fire issues. But one limitation of FR-4 is that it is not best for the purpose of transfer of the heat.
Epoxies are another best choice for the PCB assembly manufacturers as the core materials. The advantage of this material is that it is available in the market at the low cost. The limitation of this material is that it cannot provide much reliance and durability as the other materials.
Ø Metal core
The PCBs having the metal core have the metal alloy in their core. In the most cases, they have aluminium alloyed with copper or other metals as the core material. These types of PCBs have the high capability of electrical conductance. Therefore, they have capability of the heat transfer during course of process. The performance and efficiency of the process depends upon LED PCB assembly machine cost.
Aluminium LED PCBs
Aluminium printed circuit boards are the most common type of the LED PCBs. These PCBs have a base of the aluminium alloy. The alloy in the base consists of aluminium, silicon and manganese. These materials inculcate the specific properties in the PCBs that are essential for the different types of the applications. These PCBs consist of following layers.
Ø Base layer
This is the fundamental layer of printed circuit board of aluminium. It is the site where aluminium alloy is present. It consists of a sheet of aluminium, silicon and manganese. The whole printed circuit board sits on this base layer.
Ø Thermal insulation layer
This layer of PCB assembly is special and important in the thermal protection of the LED PCB. It saves the PCB from the mechanical damage. This layer of PCB consists of a ceramic polymer. When the current passes through the circuit, this layer is able to absorb the heat given out and transfer it to aluminium layer. The aluminium layer, in turn, can disperse this given heat.
Ø Circuit layer
This layer is the main layer of the PCB. It consists of the main copper circuit of PCB. There are various types of the circuit designs according to the applications of LED PCBs. In the working and cost of circuit layer, there is an important part of LED PCB assembly machine cost.
Types of LED PCBs
There are many different types and classifications of LED printed circuit boards. Each type of the PCB is special and important for the certain applications. Some of the types of aluminium PCBs are following.
Ø Flexible Aluminium PCBs
The flexible aluminium LED printed circuit boards have aluminium and polyimide in the construction. These materials bestow them with the flexibility and insulation during the lighting function. The advantage is that they have much better conducting capability due to the metal aluminium and other alloys.
The distinguishing feature of these PCBs is that they don’t need connectors and other essentials for the sake of connection. We are able to flex them in order to connect them according to our requirement. However, the flexing and bending feature in these boards is available only one time. Once we flex them and put to position, they are not available for further bending.
Ø Hybrid Aluminium PCBs
In these types of the LED printed circuit boards, there is a mixture of aluminium metal and a non-thermal material. The advantage of this non thermal material is that it decreases the cost of the PCB. Additionally, it provides the high-end capability to dissipate the heat. On the other hand, they increase the hardness and rigidity of PCB.
Ø Multilayer Aluminium PCBs
The multilayer aluminium PCBs have more than one types of materials as the dielectrics. Mostly, they have more than two sheets of materials that can conduct thermally. Due to this property, these PCBs have high and efficient performance. In addition, they also offer the better capability of dissipation of the heat. These PCBs are more related to LED PCB assembly machine cost.
However, there is a limitation of the multilayer Aluminium PCBs. The limitation is that they are not good at transfer of the heat to the metal layer. Therefore, they are different from the normal single layer and double layer PCBs.
Industrial Applications LED PCB
There are numerous industrial applications of LED PCBs due to their tremendous and enhanced popularity. Some of their industrial applications are as follows.
Ø Consumer lighting
The LED PCBs have the tremendous and excessive use in the consumer lighting. The flashlight and lamps use the LED PCBs.
In the field of telecommunication, there is a high-end use of LED indicators and displays. The reason is that they provide greater durability and performance rates. Moreover, they have better lifetime and ability to transfer heat.
In the field of medicine and surgery, the LED PCBs have the tremendous use in the surgical equipment and hospital lighting. These have the long working time and high efficiency.
