What is LED Printed circuit board | YMSPCB

LED PCB board technology has developed into many new product innovations. A good example is developing PCBS for LED lighting.

The LED is welded to a circuit board, and the chip generates light when electrically connected.The heat sink and ceramic base are used to connect the chip to absorb heat and cool the process.



PCB LED panels tend to generate a lot of heat, which makes cooling by conventional means difficult. Therefore, metal core LED circuit board is usually chosen to improve LED heat dissipation.

In particular, aluminum is commonly used to make circuit boards for LED lamps. Aluminum base board typically include a thin layer of conductive dielectric material that repositions and dissolves heat and has excellent coherence compared to unyielding PCBS.

PCB LED application

PCB LED lamps can be integrated into many lighting applications because of their outstanding energy efficiency, low cost and maximum design flexibility, such as:

Traffic light

Car headlights

Military lighting

Street tunnel lighting

The airport runway

Street lamp lighting

Photovoltaic (solar) lighting

Flashlights and lanterns

Lights in the hospital operating room

Factory lighting and so forth

YONGMINGSHENG – LED PCB, metal core PCB manufacturer

As an LED circuit board solution with many years of experience, we are able to provide LED circuit board production, procurement and assembly of components under the same roof.

We are pleased to work with you to develop custom aluminium/metal circuit boards for your specific applications.

We offer a reasonably priced standard fr-4 circuit board coated with hot aluminum that effectively dissipates heat, cools all LED circuit components and significantly improves product performance.

What is embedded LED PCB and how it works?

Leds stand for light-emitting diodes. They are semiconductor diodes, which belong to the group of electroluminescent lamps. They produce light through the combination of charge carrier pairs in the semiconductor and have appropriate bandgap. Because of its low voltage, working power, compact size, long life and stability, leds are used in industrial and consumer markets.

One of its most attractive features is its ability to generate light without generating a lot of heat, making it safe for everyday use.Its function is the main reason why leds are integrated into printed circuit boards (PCBS).

Leds are reliable and efficient enough for PCB applications. They act as light, especially in non-touch film switches. Integrated LED circuit boards are commonly used for polyester graphics and rubber keyboards.

The user interface

Circuit boards are commonly used in the lower circuit of thin-film switches, especially because they provide it.Display LED display window.

These are usually easy to integrate into PCB switch designs, but there are some options when it comes to which type of LED to use.

Single point and block LED

They are the most versatile and work best with almost all types of surface materials. Note that matte or textured surfaces are best used for larger light diffusions. It is also important to remember that although leds cannot touch the active area of the switch, they can be convinced by graphical manipulation that they are part of the switch.

Integrated or surface-mounted single point LED

Integrated or protruding single point leds can be installed in the lower ring of the lower layer. For these types of leds, different colors can be used, including two-color leds.

When the graphics layer is formed to receive the LED, the end connection is easily terminated from the same end of the connector.Note that you do not need to save the LED completion chart in a separate queue.

Advantages of integrated LED PCB

As electronic components become thinner and thinner, it is advantageous to use LED film switches because it makes product delivery and final assembly easier.

These integrated LED CARDS are best suited for low illumination, consumer, equipment, medical equipment, light to medium industrial and certain Marine and aerospace applications. Regardless of the application, there are many advantages of integrated LED board:

Light and unobtrusive

Low cost backlit film switch

Resistant to dust and moisture

Easy integration into complex interface games

Low energy consumption

There are many colors, sizes and strengths can be chosed

It can be used for flexible silver film switch and flexible copper film switch.

If LED is integrated into circuit board, it is easier to combine LED film switch with keyboard, touch screen and other types of film switch. Even when creating complex backlight switch components, built-in or embedded LED PCBS provide greater design freedom.

The small thickness of LED film switches reduces the total area of these complex switch interfaces. Designers and engineers often choose integrated LED PCBS when inspecting and updating products.

In general, LED PCBS provide the most user-friendly backlight for thin-film switches. Sometimes they are a better choice for small backlit ICONS and symbols, because uniform backlighting of larger ICONS and symbols with embedded LED PCB circuits is not easy to achieve.
