What Is an LED PCB
LEDs are semiconductor diodes that belong to the category of electroluminescent lights. And they produce light by combining sufficient energy gaps with charge-carrier pairs in a semiconductor. LED PCBs are single or double color LEDS that come in white or blue.
Hence, they act as indicator lights for membrane switches. And they are most suitable under rubber keypads and polyester materials. So, LED PCB Assembly is the soldering of Light-emitting diodes to a PCB, by a manufacturer, along with a small chip that produces light when electrically connected.
Here are the major types of LED printed circuit boards available in the market.
Single Layer LED PCB
The single-layer LED PCB has only one layer of the substrate or one side of the circuit. The single layer is usually made of copper, which is a great conductor. Also, this PCB is relatively straightforward, very simple to design, and pretty affordable.
Flexible LED PCB
Flexible LED PCBs consist of a flex material that can twist in any direction without breaking. So, they come in different forms like single, double, and even multiple layers. However, they are one of the most expensive LED PCBs because you need to print the circuit on them. Hence, they are durable, and you can use them for environmentally hazardous areas.
Multi-Layer LED PCB
From the name, this type of PCB has two or more layers of LED PCB. The numerous layers stick together with the help of a special type of glue. Also, you can find different insulators in between the layers. The work of the insulators is to keep the LED from melting because of excess heat.
Rigid LED PCB
This PCB is the exact opposite of the flexible LED PCB. The rigid PCB is quite stiff and doesn’t bend easily like the flexible ones. But, most manufacturers prefer to use it when they want an electronic device to stay in shape. So, you’ll mostly find them on computers. And they come in various forms; single, double, and multiple.
Hybrid LED PCB
This PCB comprises a non-thermal material merged with a base metal like aluminum. Most times, the hybrid LED PCB comes with an aluminum substrate and a conventional FR4 binding. With both materials joined together, it's simple for the PCB to dissipate heat, making it more rigid but less flexible.
Why Is LED PCB Assembly
These days, with many electric devices getting smaller and thinner, more engineers and manufacturers use LED PCBs. Hence, using LED PCBs comes with loads of benefits.
The Applications of the LED PCB
Because LED PCBs have outstanding design flexibility, exceptional energy efficiency, and low cost, you can incorporate them in various lighting applications. And they are as follows:
What Are the Design Techniques Applied for
LED PCB Assembling?
Pitch is a design method you can use on different parts of the board. And there’s an effective way to achieve this feat if you’re dealing with the copper layer. Hence, it’s imperative to cover one side of the board with pads arranged in the matrix.
Also, the assembled LED has four pads, and the components usually get arranged on the driver’s side. And avoiding a large LED is essential for resolution and display effect, especially for a smaller LED pitch.
Also, it’s crucial to note that there is a range you should use. Hence, the LED pitch is usually between 1.0 to 4.0 (mm). And the or SMT pitch ranges between 0.45 to 1.6 (mm).
The LED installing holes are non-penetrating, and they have individual specifications. So, the installing holes should have a board thickness of -0.5mm. Plus, it’s vital to stick to a drilling angle of about 1300. Also, it’s ideal to have a depth tolerance of not more than ±0.2mm. The diameter tolerance, on the other hand, should be ±0.5mm.
If you notice that the holes have inadequate distance at the copperless area, you have to plate through holes. That way, your copper won’t be bare at the margin of vias.
It’s essential to maintain enough space between the outer margins and the pad.
And it’s because when there’s a lack of space, you may experience problems like copper exposure and milling detections.
