LED PCB Assembly: one stop LED lighting PCB solution

What is LED PCB Assembly?

The structure of LED PCBs is made of fiberglass, metals, and some other materials required to
make a connection with the electronic components.

The technology of the circuit board itself complements its valuable role in supporting LEDs
as it is essential for many applications.

The physical support of the LEDs conveys the heat away from the bulbs and boosts their performance to prevent damages.

Generally, LEDs emit more heat than other electronic parts that is why pairing with PCB  dissipates the heating attribute and gives it better usability.

It requires to have metal core PCB especially the aluminum core PCB to make it worthwhile.
The aluminum PCB includes a thin layer of conductive dielectric material that helps in  transferring and dissipating the heat with efficiency.
When the electricity passes through the components at a defined voltage the manufacturers can control the amount of electricity
and accumulate it according to need.

LED PCB Assembly methods

For the LED light circuit board assembly,
It entails two primary ways for attaching the electronic components and LEDs to the printed  circuit boards.
The following methods are used for the assembly:

  • Surface-Mount Assembly:

This method is done by mounting the components directly to the board surface.
It is an automated process that offers excellent flexibility and enables high-density connections
for LED applications.

First, the solder paste is placed on the board, then the components are placed into the machine through pick-and-place,
after that the solder joints are heated with the board, and lastly, ensures it functions correctly.

The Surface-Mount LED circuit boards are perfect for applications with complex circuitry in smaller devices.

  • Thru-hole Assembly:

This technique needs to drill holes in the PCB and put the components through these holes
and then apply solder to hold the pieces.

It is a stronger and durable method that helps the equipment to run through extreme environments and high temperatures.
To get assurance, it also requires multiple inspections for accuracy and efficiency.

Applications of LED PCB Assembly

Modern electronics are getting smaller and effective that requires to have high functioning PCBs.
The demand for LED PCBs are increasing for the following applications:

  • Consumer lighting:

The demand is quite high for the LED PCBs in consumer lighting products,
Such as flashlights, lanterns, lamps, spotlights, solar-powered lights, and so on.

  • Consumer electronics: 

Due to immense heat sensitivity, consumer electronics are commonly used in computers, tablets, smartphones, televisions, etc.

  • Telecommunications:

LED indicators are common in the telecommunication industry for their endurance and heat transferability.

  • Transportations:

The traffic and transportation systems utilize the benefits of LED PCBs in vehicles and spotlights. The headlights, brake lights, indicators of vehicles and traffic and signal lighting, highway tunnel lighting and street lighting as well as interior lighting, air landing, and running lights also use LED PCBs.

  • Medical Industries:

The hospital lighting and the lighting tools used in surgeries, medical examinations,
And medical scanning tools utilize the LED PCBs for better functionality.

Introduction to LED

LED stands for Light Emitting Diode.

They have been the latest technology that offers high-quality lighting.

The Light-emitting diode are a solid-state device that does not need additional heat to create a light, on the contrary, the light emits when the current

flows through them.

There is a recombination of electrons in the semiconductor with the electron holes. This process releases the energy that is responsible for creating

photons.

The usage of LED is not limited to lamps or bulbs, on the contrary, you can see their application over a wide range of both industrial as well as

consumer products. LEDs are a strong form of energy, but it requires effort and hard work to create robust LEDs.

Introduction of LED PCB Assembly

The evolution of Printed Circuit Boards has helped the manufacturer come up with better or sophisticated Printed Boards.

One of the major advancements of PCB technology is LED Printed Circuit Boards.

The modern Printed Circuit Boards incorporate LEDs.

These LEDs make it possible for the current to pass through the components at a defined voltage. Since the manufacturers are able to control the

amount of current, thus it is possible for them to come up with LED PCBs that can operate at high voltage.

The manufacturer’s solder LEDs to the circuit board along with a chip that generates light when connected electrically.

In order to bound the chip, they use a ceramic base along with a thermal heat sink.

An important thing to remember here is that LED PCB boards tend to generate heat at a high volume. Therefore, it is extremely difficult to cool them

down using orthodox methods.

Using a metal core PCB board is usually the first preference especially for LED application.

The reason being, a metal core PCB board has a higher ability to dissipating the heat, in comparison to the conventional boards.

Likewise, Aluminum PCB is a good choice for manufacturing circuit boards for LED lights.

LED light industry on whole has started to incorporate Printed Circuit Board technology due to its endless benefits. Some of these benefits include

enhanced light quality, improved shelf life among others.

Aluminum for LED PCB

The aluminum base are usually the most common LED PCB. They show effective results and offer high performance.

The conductive link between the Heat Sink and the IC is basically the thermally conductive dielectric layer of the aluminum base. This concept is

unlike FR4.

The aluminum and the copper have enhanced and improved the characteristics of the thermal expansion to a great extent.

Even the dimensional stability of an MPCB is much more than the conventional insulating material, FR4.

The great thing about the aluminum base is the versatility it offers. Since there are different types of aluminum available serving different purposes,

thus it is possible to have more specialized LED Printed Circuit boards.

Below, we are going to shed some light on different types of Aluminum.

Types of Aluminum

All these types are highly effective and they offer great results.

We are not doing a comparison on which type is better; on the contrary, we are providing the basics of every aluminum type.

Reasons to Choose LED Aluminum  PCB

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it.

Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.

The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the

semiconductor.

White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.

Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light.

Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics.

The first visible-light LEDs were of low intensity and limited to red. Modern LEDs are available across the visible, ultraviolet (UV), and infrared

wavelengths, with high light output.
