Manufacturing different led lighting devices require the best materials. The importance of using the best materials for manufacturing electronic devices cannot be underplayed because if the materials are sturdy; it will help in increasing the lifespan of the devices.
At the same time, Printed Circuit Boards (PCBs) have become a standard for producing electronic devices. Because of the excellence of these boards, you are confident that the devices you want to manufacture will provide the best service to your customers while lasting for many years.
In this article, we want you to understand everything about the LED PCB. This is not only one of the most used forms of circuit boards. It also makes the task of manufacturing electronic devices easier.
Meaning of LED PCB
First, we want you to understand the meaning of LED PCB because that is what you need to have in mind to understand how the board works in entirety.
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.
Metal core circuit boards are highly favoured in this case, and the aluminium PCB is one of the most used because its thin layer of thermally conductive dielectric material can conveniently dissipate the heat from the circuit board.
You may be wondering about the possible use cases of LED PCB. The applicable cases are many, but we will mention some of the popular ones.
It will interest you to know that the medical industry is one of the major beneficiaries of the applications of LED PCB.
Most of the medical equipment you know or see in the hospital are made from LED PCB. The reason for that is because LED PCB board tend to provide more light than traditional circuit boards would.
Also, preference is made for lighting tools used during medical examinations and surgeries. To ensure that the circuit boards are functioning effectively, aluminium PCB will be used during the manufacturing process because it effectively transfers heat while maintaining the stability of the medical pieces of equipment when in use.
Aside from being used in the medical sector, LED PCB can also be used in the telecommunications industry. There are two major roles played by these circuit boards in telecommunication devices.
First, LED PCBs (especially those manufactured with aluminium PCB) effectively transfer and dissipate heat from the board. Thereby, you are confident that the circuit board will stand the test of time because it is not in immediate danger of malfunctioning because of overheating.
Second and most important, LED PCB are used in the telecommunication sector because of the boards of the overall importance of the displays and indicators on the boards in telecommunication equipment.
If you are conversant with how the IT industry works, you will understand why LED PCB are mostly used instead of the other circuit boards. For instance, computers and Personal Computers (PCs) heat the most after some hours of use. That could cause damages to the internal components of the computers.
However, if the PCs and computers were manufactured with LED PCB, the damages will be limited because of the effective dissipation of heat from the circuit board.
This time, we are looking at how LED PCB can be the last resort for automobile manufacturers that want to improve on the quality and effectiveness of their indicators and brake lights.
LED PCB are mostly preferred during automobile production because of their increased efficiency and competitive pricing.
The four (4) applications of LED PCB are not the only ones. Instead, there are several other applications and use cases of the circuit boards you need to know about.
First, LED PCBs are used in producing consumer devices, such as:
- Power converters
- Aviation applications
- Decorative led lights
- Marine applications
- Lower-light environments
- Concealed light
- Elevator led lighting and
- Camping accessories
Manufacturing Process of LED PCB
Now, let us delve into one of the most important aspects of LED PCB production. If you are a circuit board manufacturer or consumer, you need to be armed with the knowledge of how the LED circuit board are manufactured.
So, here are the steps involved in the designing and manufacturing of LED Printed circuit board:
1. LED PCB Assembly
The first process involved in the manufacturing of LED PCB board is to assemble the properties. Note that you may want to source the materials if you are sure of what to buy and what not to buy. But, if you are not certain, you can always contact the LED PCB manufacturer to help you source the materials and components that will be used.
2. LED PCB Manufacturing
Once the circuit board components are ready, the next step is to start manufacturing the board.
Depending on your agreement with the PCB manufacturer, a prototype may be produced first so you will have an overview of what the final product will look like.
Important things to Note
We must mention that you need to have some things in mind before you decide to manufacture LED PCBs.
Here are some of the important points you need to take note of before any other thing:
You have to decide on the number of layers that the circuit board will have. Your choice depends on several factors, such as the capacity of the device it will be used, and the efficiency of the layers.
Ideally, there are three different types of layers that you can use on your LED PCB. They include:
- One layer (which is popular)
- Two layers and
- Four-layer LED PCB. This type is mostly used for outdoor LED Screen.
The role of lumens in circuit boards, especially LED PCBs cannot be ruled out. There is a need for more lumens to be added to the circuit board, and an excellent way to do that is via a super white solder mask.
The rule of thumb is that the more super white solder masks are used on the circuit board, the more the lumens.
On the other hand, the importance of lumens on LED PCB cannot be ruled out. Generally, lumens are the singular reason why your LED PCBs will give your lights better brightness.
So, if you want your LED PCB to be more efficient in terms of providing more light, it makes sense that you liaise with the PCB designer to increase the number of lumens on the board.
The other factor you must put in place is to increase the number of LED lights on the circuit board.
You should always remember that the work of LED PCBs is to use the LED lights to increase the thermal performance of the circuit board.
For that reason, you must always increase the number of LED lights on the LED circuit board so that the thermal performance of the board will be good.
Also, the absence of enough LED lights could bolster an increase of the temperature of the circuit board. And when that happens, the LED light chips will die.
Therefore, do not fail to add lots of LED lights so that your LED PCB will increase the material thermal performance of the circuit board while reducing the risks of destroyed light chips.
How to Reduce LED PCB Temperature
Aside from adding lots of LED lights to reduce the temperature of the circuit board, you can use another method.
One of the most effective methods of reducing the temperature of a LED PCB is to use aluminium as the base material.
Types of LED Used in PCBs
If there is anything you must be intentional about when designing a LED PCB, it has to be the materials used for the production.
Also, we must point out that these materials are mostly based on LED. So, you are not overly concentrating on the circuit board material, but on the type of material that the LED is made of.
Here are the LED types you want to consider when you want to manufacture the circuit board:
This type of LED PCB is manufactured in the same way that the Surface Mount Technology (SMT) is used to manufacture other circuit boards. The design process here entails mounting the LED on the bottom layer of the lower circuit.
Besides, there may not be a need for you to emboss the graphics layer to put up the LED. That is because of the provision of LED termination on the separate connector tail as of the switches.
The Surface Mount LED is also called Integral Single Point LED, and it is available in a variety of colour ranges.
Also called Single Point LED, the Block LED is another type of LED PCB. It will interest you to know that this is one of the most used types of LED PCBs because of the multiple use cases.
Second, a Block LED PCB provides excellent light diffusion because of the matte or textured surface.
Moreover, you want to adopt this type of LED PCB into your next circuit board design because of the excellent performance with almost every kind of finished material surface.
Types of LED Printed Circuit Boards
Manufacturing a LED Printed Circuit Board (PCB) requires the best circuit boards.
Here are some of the popular and most efficient LED circuit boards that PCB consumers love to use:
As the name signifies, a hybrid LED circuit board is the type that uses two components. The composition of the board involves using a material that has a basic metal core (such as aluminium) and another that has a non-thermal material.
The reason for the combination of the two materials is to bolster the heat dissipation of the circuit board.
Here are some of the benefits of designing your circuit board with hybrid LED PCB:
- The circuit board is more rigid and that makes it one of the strongest LED PCBs.
- Hybrid LED PCBs are affordable.
LED PCBs also have some disadvantages, including non-flexibility, which makes it hard to bend the circuit board.
2. Single-Layer LED PCB
Unlike the hybrid LED PCB, the single-layer LED PCB only has one layer of substrate that also doubles as the only side of the circuit board.
PCB consumers love this type of LED PCB because it is easier to design, which means they will spend less and have their circuit board after a few days.
Also, a single-layer LED PCB can be used in a variety of applications. So, if you are looking for a versatile LED circuit board, this is the one to go for.
3. Flexible LED Circuit Boards
Most times, PCB consumers want to design circuit boards that can twist and bend at will. That makes the flexible LED circuit board one of the best you can find out there because it can be moved in different directions.
The flexibility of the board is one feature you cannot ignore. For one, you rest assured of saving some money that you could have spent to create different circuit board designs to align with what you want the board to do.
If you are looking for a LED PCB that can be used in hazardous environments, the flexible LED PCB is the one to go for. The shock resistance to oils of high temperature, the waterproof and the shockproof are some of the features that will preserve the circuit board even when it is exposed to hazardous environments.
4. Multi-Layer LED PCB
Do you want to design a circuit board that has multiple layers? It wouldn’t be a bad idea to manufacture a multi-layer LED circuit board because this is the type of LED PCB that can provide the kind of efficiency you want.
The design of this type of LED circuit board involves the sticking of multiple layers between different types of insulators. A special type of glue is used to make this possible.
On the one hand, the inclusion of multiple layers is to enhance the complicated electrical applications where the circuit board may be used.
On the other hand, the multiple insulators used on the board are there to prevent melting of the LED PCB, especially when the heat becomes excessive on the circuit board.
5. Rigid LED PCB
The other type of LED PCB is the Rigid LED PCB. It is called rigid because it is not in the league of the flexible LED circuit board that can be bent.
Instead, a rigid LED PCB is designed with solid materials that double as the substrates. These materials are the primary reason why the circuit board cannot be twisted or turned to different directions because they are meant to be static.
Despite the obvious disadvantage of being hooked to a particular direction, a rigid LED PCB is also important in some cases. For example, you want to use it to design a circuit board that you do not want to alter its original form or design. It is also the best type of LED PCB to use when you want to manufacture circuit boards in different forms, such as multilayer, single and double.
LED PCB Materials
There are several materials out there that can be used to design LED circuit boards. They are discussed below so you can understand how they work and select the one that works best for you.
1. Composite Epoxy Material (CEM)
Composite Epoxy Material (CEM) is one of the most used types of materials for LED PCB production. It is a strong competitor to the Flame Retardant Grade 4 (FR-4) material.
Here are the different classifications of the Composite Epoxy Material (CEM) so you will understand how the material is used for circuit board design.
CEM-1 PCB Material
The first classification is CEM-1. Generally, a Composite Epoxy Material (CEM) is produced from a cellulose-paper-based laminate that has a layer of woven glass fabric.
The CEM-1 is the most preferred because it has the most flame-retardant properties that help in the mass production of circuit boards. Besides, it is affordable to manufacture this type of circuit board.
We must mention that the CEM-1 LED PCB has some disadvantages that include limitations to single-sided circuit board production because of the impossible metallization through holes.
CEM-3 PCB Material
Although the CEM-1 Material is one of the most used, it is not the only classification of the Composite Epoxy Material (CEM).
The CEM-3 Material is another classification that the PCB consumers always want to use to design their circuit board.
The CEM-3 Material is preferred because it has a better performance on heat transfer. So, if you have been looking for a way to facilitate heat dissipation and transfer from your LED PCB, the CEM-3 PCB material is the one to use.
2. Flame Retardant Grade 4 (FR-4)
The FR-4 is another type of LED PCB material. The primary reason why PCB consumers want to use this type of material is because of the least vulnerabilities of the material when compared to the others, especially the CEM-1 material.
Custom PCB Led Lighting
As the popularity of Printed Circuit Boards (PCBs) continues to grow, PCB consumers are looking for additional ways to make the most out of their circuit boards.
Custom PCB are now the in-thing with many PCB consumers looking to design LED circuit boards that meet their specifications.
If you must design a custom PCB, here are some of the factors you must consider:
1. Use Quality Soldering Material
The first thing you must consider to design custom LED PCB is the quality of the soldering material.
If the soldering material is not durable, it will rub off on the circuit board. Os, always ensure that the soldering material is of the utmost quality because that will reduce the risks of making mistakes when designing the LED circuit board.
2. Maintain Preventive Measures
Higher heat dissipation is required when designing custom LED PCB because any slight mistake at this point could cause serious damages to the entire circuit board.
How to Choose a LED PCB Manufacturer
When you are ready to hire a LED PCB manufacturer to design the board for you, here are some of the attributes you want to look for:
1. Ability to Meet Your Requirements
You will find it pleasurable to hire the services of a LED PCB manufacturer that will take care to attend to your needs.
You want to hire a manufacturer that can meet most of your requirements, so you will be satisfied with the LED PCB after it is designed.
Some of the requirements you want the LED PCB manufacturer to meet include:
- Proper hole dimensions and
- Power rating
2. Delivery Rate
Depending on the quantity of LED circuit boards you want to design, you want to hire a manufacturer that can manufacture and deliver the circuit board in the shortest time possible.
3. Production Costs
Last but not least is that you need to consider the cost of the LED PCB you want to manufacture. The service costs of the manufacturer should be something you can accommodate in your budget so you don’t overspend.
You now understand all there is to manufacturing LED PCB. So, the next time you want to design this type of circuit board, we at Ray PCB will be ready to help you design the type of LED circuit board you want, whether custom or otherwise.
LED PCB Board technology has evolved to bring many new product innovations. A good example is the development of PCB for LED lighting. The LED is soldered to the board and has a chip that generates light when connected electrically. A heat sink and a ceramic base are used to connect the chip in order to absorb the heat and cool down the process.
A PCB LED panel inclined to initiate a high volume of heat, making it laborious to cool through traditional ways. Hence, mental core LED circuit boards are customarily picked up for their LED’s enhanced heat dissipation capability. In particular, aluminum is often used for the production of circuit boards for LED lights. The aluminum PCB generally includes a thin layer of thermally conductive dielectric material relocate and dissolves the heat with exceptional coherence than an unyielding PCB.
PCB LED Applications
The PCB LED lights can be integrated into many lighting applications thanks to their excellent energy efficiency, low cost and maximum design flexibility, such as:
- Traffic lights
- Car headlights
- Military lighting
- Street tunnel lighting
- Airfield runway

What Are Embedded LED PCBs board And How They Work?
LED stands for Light-Emitting Diodes, they are semiconductor diodes and belongs to the group of electroluminescent luminaries and produce light by recombination of pairs of charge carriers in a semiconductor with a suitable energy band gap. Due to their low voltage, operating power, compact size, long life and stability, LEDs are used in the industrial and consumer market. One of its most attractive features is its ability to generate light without generating much heat, making it safe for daily use. Its features are the main reason why LEDs are integrated into printed circuit boards (PCBs). LEDs are sufficiently reliable and efficient for PCB applications. They serve as light, especially in non-touch membrane switches. Integrated LED circuit boards are often used in polyester graphics and also in rubber keyboards.
Circuit boards are often used for the lower circuit of a membrane switch, especially because they provide it. Show window with LED displays. These are often easily integrated into the printed circuit board switch design, but there are some options when it comes to what type of LED to use.
They are the most versatile and work well with almost all types of surface materials. Note that a matt or textured surface is best used for greater light diffusion. It is also important to remember that although LEDs cannot pass the active area of a touch switch, they can be graphically manipulated to make them believe that they are part of the switch.
Integrated or Surface-Mounted, Single-Point LED
An integrated or protruding single-point LED can be installed in the lower circle of the lower layer. For these kinds of LEDs, different colors are available, including two-color LEDs. It is quite easy to allow termination from the same end of the connector as the switches when the graphics layer is shaped to receive the LEDs. Note that you do not need to save the LED completion chart in a separate queue.
Advantages of Integrated LED PCBs Board
As electronic components become smaller and thinner, it is advantageous to use LED membrane switches because it enables easier product delivery and final assembly. These integrated LED cards are best suited for low light, consumer, device, medical device, light to medium industrial, and certain marine and aerospace applications. Regardless of the application, the benefits of the integrated LED pcb board are numerous:
- Led Light, unobtrusive
- Low-cost backlit membrane switches
- Resistant to dust and moisture
- Easy to integrate into complex interface games
- Low energy consumption
- Available in a variety of colors, size, and intensities
- Can be used in flexible silver membrane switches and flexible copper membrane switches
If the LED lights is integrated into the board, it is easier to combine the LED membrane switch with keyboards, touch screens and other types of membrane switches. Built-in or Embedded LED PCB Board offer greater design freedom, even when complex backlight switch assemblies are created. The small thickness of an LED membrane switch reduces the total area of these complex switching interfaces. Designers and engineers often choose integrated LED PCB Boards when inspecting and updating products.
In general, LED PCB circuit Boardprovide the most accessible backlight for membrane switches. Sometimes they are a better option for backlighting small icons and symbols because the uniform backlighting of larger icons and symbols with embedded LED PCBs circuits is not so easy to achieve.
