LED is an acronym for light emitting diode, which is semiconductor diodes. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. In general, the aluminum PCB contains a thin layer pf thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.

Like other semiconductor devices, PCB is the best method to electrically connect the LED components. And a PCB with LED components soldered is usually called as “LED PCB”. In this passage, we will provide you everything about the LED PCB assembly, if you are interested in LED PCB please check and read the content below for more.

What are the 5 tips of LED PCB assembly?

1.      Knowing the types of aluminum in LED PCB assembly

The aluminum base is 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.

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

·  Flexible Aluminum

·  Hybrid Aluminum

·  Multi-Layer Aluminum

2.      Get into the design rules of LED PCB

For an LED PCB, you need to cater to two main aspects of the design. First, it is important to ensure that the LED sits within the circuit board’s drilled holes. Ensure that the holes are part of the design. Second, you need to focus on the distance between the holes. 

You need to save the file in the industry Standard format of the Printed Circuit Boards i.e. the Gerber File. Ensure that the Gerber files have the required number of layers. Each layer will be showing different aspects of the Printed Circuit Board.

After you have the Gerber file, you need to create a text file that contains information regarding the layer content as well as the board dimensions.  Pay close heed to the required voltage and ensure that the LED has the ability to withstand the power supply that you need to your Printed Circuit Boards.

3.      Avoid defects during LED PCB assembly

The LED PCB assembly may suffer from gradual performance degradation, and it is challenging to identify its root cause. Your custom LED PCB may be subject to trace degradation, oxidation, incorrect copper weight, condensation, and solder flux corrosion.

If you inconsistently apply solder paste, it can lead to short or open circuits in the LED PCB. If you use it in limited quantity, the solder joints will be more prone to rupture. If you haphazardly use it in excess, it may connect with the nearby connections and cause short circuits.

In this case, you will burn not only the LED but also the sensitive nearby electrical components. You should make sure that the LED PCB does not get environmental contamination. Furthermore, you may also use electrical testing to find the location of the short and open circuits.

4.      Knowing the applications of LED PCB

PCB LED lights have excellent energy efficiency, low cost and maximum design flexibility, so it can incorporated into numerous lighting applications.

Computer

LED displays and indicators are more and more popular in the computer applications. And aluminum PCB LEDs are an ideal solution because of the heat sensitivity of computer machinery. Expect for LED applications, aluminum PCBs are also used for the computer parts.

Medical

Lighting tools used in surgeries and medical examinations commonly use high-powered LED lights, and these LED lights often use aluminum PCBs, which is primarily because of the durability and heat transfer capabilities of aluminum PCB LEDs. Expect for lighting tools, medical scanning technology often uses aluminum PCBs as well.  

Automotive

Aluminum PCB LEDs also are used for cars on indicators, brake lights and in headlights, as well as other applications. There are some factors making the aluminum PCBs be ideal within the automotive industry, such as the durability and competitive prices.

5.      Pay attention to the thermal issues during LED PCB assembly

LEDs, diodes, and other electronic components in the LED PCB may produce heat while functioning. If they provide extreme hear, it can damage them or affect their performance.

There must be some supplemental cooling to maintain their temperature within their safe, defined limits. One way is to use a heat sink in your LED PCB design. It will prevent overheating of any electronic devices. Heat sinks are optimized and designed to allow the electronic components to operate within the safe limits.
