· 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
- 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.
- 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.
- 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.
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.
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.
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.
