Friday, July 26th, 2024

The led light circuit board, also called the LED circuit board, is actually the abbreviation of the printed circuit board (PCB). PCB is a stable carrier of electronic components, which not only realizes electrical connection, but also plays a supporting role. In LED lamps, the PCB board integrates LED components, and through this integrated PCB board, the LED lamp can realize its function. The driving circuit of the LED lamp, such as constant voltage drive, constant current drive, PWM drive, etc., are all integrated on this small circuit board, which is necessary to light up the LED lamp beads. Therefore, it can be said that the circuit board of the LED lamp is the printed circuit board inside it, which is responsible for converting electrical energy into visible light, and controlling the brightness and performance of the LED through different driving methods.

Advantages of led light circuit board

Lower power consumption: Replacing incandescent lamps with LED lamps can reduce power consumption by more than 80%.

Longer life: The service life of LEDs can generally exceed 20,000 hours, and they can be used around the clock for 3 years, which is 25 times longer than incandescent lamps. Not only can it save costs, but it also reduces the frequency of replacement.

Higher efficiency: Incandescent lamps release more heat. LED lamps can reduce it by up to 20%. This means that while using more powerful LED lamps, unnecessary heating can be reduced.

Smaller size: Due to their small size, LED lamps can have various sizes and can be used in different places. Manufacturers can add LEDs to anything, whether it is electronic equipment or cars, and even traffic lights and signs on the road.

Environmental protection: Compared with other bulbs, LED lamps do not contain mercury. Therefore, LEDs have less impact on the environment and are easier to handle.

LED is the abbreviation of light-emitting diode, which is a semiconductor diode. LEDs are soldered to a printed circuit board and equipped with a chip that generates light through electrical connections. A heat sink and a ceramic base are used to connect the chip. Undoubtedly, LED PCB is the core of LED lighting. An LED PCB tends to generate a lot of heat, but it is difficult to cool it by traditional methods. Metal core PCB is widely used in LED applications due to its strong heat dissipation ability, especially aluminum is often used in the production of PCB for LED lamps. Usually, aluminum PCB contains a thin layer of thermal conductive medium material, which can transfer and dissipate heat much more efficiently than traditional rigid PCB.

Why led light circuit board use mcpcb

Aluminum substrate is a metal-based copper-clad board with good heat dissipation function. Generally, a single-sided board consists of three layers, namely circuit layer (copper foil), insulation layer and metal base layer. There are also designs for high-end use as double-sided boards, with the structure of circuit layer, insulation layer, aluminum base, insulation layer and circuit layer. Very few applications are multi-layer boards, which can be made of ordinary multi-layer boards with insulation layer and aluminum base.
LED aluminum substrate is PCB, which also means printed circuit board, but the material of the circuit board is aluminum alloy. In the past, our general circuit board material was glass fiber, but because LED generates more heat, the circuit board used for LED lamps is generally aluminum substrate, which can conduct heat quickly. The circuit boards used for other equipment or electrical appliances are still glass fiber boards!

How are LED patches installed on PCB boards?

Use double-sided PCB board, patch LED on the front, and drive power circuit on the back. LED can be designed into a circle shape, through metallized holes to the back, there are plenty of places to handle these leads
On the corresponding pads of PCB board, brush tin, use patch machine to apply it, and then reflow soldering, it is on, but in actual operation, you need to pay attention to many problems, anti-static, equipment quality, etc.

Do You Know Who Is the King Among the Metal Core PCBs?
Saturday, October 14th, 2023

Have you ever encountered these problems: your LED beads overheat, lose brightness, and shorten their lifespan? Have you ever thought of using a better PCB material to solve these problems?

If you are considering this question and your answer is yes, then you must learn about thermal-electric separation copper PCB, the king of Metal Core PCB (MCPCB), which can make your LED lamps achieve unprecedented effects.

What is Metal Core PCB?

It is a type of printed circuit board that uses metal material as the heat dissipation layer, commonly used in LED and other high-power electronic products. There are many types of metal core PCB, among which the most common one is aluminum PCB, which has a thermal conductivity of about 1W, suitable for low-power LED lamps.

However, with the development of high-power electronic products and high-frequency PCBs, aluminum PCBs can no longer meet the requirements of heat dissipation and volume. Therefore, more and more products choose copper PCB, which has a thermal conductivity of up to 400W, 400 times that of aluminum PCB. But ordinary copper PCB also has a drawback, that is, its circuit layer and heat layer are on the same layer, which requires connecting the beads and the heat layer through an insulating thermal conductive material, which will reduce the thermal efficiency. To solve this problem, a more advanced copper PCB structure has emerged, called thermal-electric separation copper PCB or SinkPad PCB.

Introduction to Thermal-electric Separation Copper PCB

The feature of thermal-electric separation copper PCB is that its circuit layer and heat layer are on different layers so that the beads can directly contact the heat layer, achieving zero thermal resistance heat dissipation. This structure can greatly improve the luminous efficiency and lifespan of the beads, and reduce light decay and heating. Thermal-electric separation copper PCB is very suitable for single high-power beads, especially the COB package, which can make the lamp achieve better effects. In addition, thermal-electric separation copper PCB can also be made into different shapes and structures according to different design needs, such as copper protrusions, copper recesses, parallel heat dissipation, etc.

Below is the structure diagram of ordinary copper PCB and copper substrate bump thermoelectric separation as an example to give you a more intuitive understanding of the advantages of thermoelectric separation copper substrate processing technology.

(Diagram_structure_comprasion)

From the ordinary copper PCB diagram on the left, it can be seen that the heat dissipation needs to pass through the insulating and thermally conductive material (purple part in the picture), which is more convenient to process. However, after passing through the insulating and thermally conductive material, the thermal conductivity is not so good. This kind of suitable for low-power LED lights, which is enough.

If the heat dissipation requirements are very large on automotive LED lamp beads or high-frequency PCBs, both normal aluminum PCB and copper core PCB cannot meet the requirements. It is common to use thermoelectric separation of copper substrates. Because the circuit trace and thermal layer are on the different layers, the thermal layer part directly contacts the LED beads (as shown on the right side of the picture above) to achieve the best heat dissipation (zero thermal resistance) effect.

Besides, there are also many various surface treatment options for the thermal electric separation copper PCB, such as OSP, immersion gold, ENIG, immersion silver, silver plating, ENEPIG, etc. It can be carried out according to different needs, and the surface treatment layer and lifespan are reliable.
