    LED PCB Thermal Dissipation Technology and Development Trend

    Led industry developing until today, Led lights have become energy save, electricity save, highly efficient, quick reaction, long work life, without Hg, Environment friendly. However, led light can only convert 20% of energy into light and 80% into heat. If the heat can be transferred away from the led bulb, it would let the led surface temperature overheat, then affect the Led bulb’s stability, luminous efficiency and work life. Thus, how dissipating the heat from the Led bulb is a significant problem.

    LED PCB Thermal Energy Transfer Substrate Layer Introduction


    SMT allows the miniaturization of electronic products whereas the dimensions of antecedently used perforated insert parts will now not be reduced.


    SMT makes the function of electronic products more complete. There are no perforated components used in the Integrated Circuit (IC) any longer.


    The use of SMT can realize the batch production of products as well as the automation of production. After the adoption of SMT technology, the PCBA manufacturers rely on low cost and high yield to produce high-quality products to meet customers’ demands and strengthen market competitiveness.


    The use of SMT can adapt to trends such as the development of electronic components, the development of integrated circuits (ICs), and the diversified applications of semiconductor materials.

    LED PCB Thermal Energy Transfer Substrate Layer Introduction

    Some will say, “Led heat transfer board can transfer heat from an Led chip. Can this show that it has excellent heat transfer ability?” The answer is “Yes.” We make two conclusions about heat transfer from the above introduction: one is a Led die substrate, and the other is an energy transfer system. Two ways to transfer the same energy generated by the Led die, pass by the Led die substrate to the system PCB, then pass to the air, and let the heat energy evacuate to the environment.

    The system PCB is the last part of led thermal transfer to the cooling fin, housing or air. In recent years PCB production technology is already matured. Initially, Led bulbs used standard PCB, but now more high-power Led bulb applications to request high heat energy transfer efficiency, but the standard PCB can’t meet the request. To solve the high-power Led bulb thermal energy problem, metal core PCB (especially aluminum) has been widely used in Led bulb production. Metal usually can put heat efficiently, solving the Led bulb’s high-power heat energy transfer problem.

    Though metal core PCB can transfer thermal energy to the air efficiently, the heat evacuation from Led die to the metal core PCB is still not well, so if we want to let the Led bulb evacuate heat more efficiently, we still need to solve the problem, how the heat energy can transfer faster from Led die substrate to the MCPCB.

    The Led die, substrate board, is an intermedium between the Led die and LED PCB that consist of eutectic or flip-chip, Led die and wiring bonding. Considering thermal energy evacuating, most Led die substrate boards adopt ceramic substrate. Classified by the bonding wire-making method, the Led substrate board can be classified into three types: thick film ceramic board, low-temperature burn ceramic board, and thin film ceramic board.

    Because the gold wire limited the heat energy evacuated from the Electrode efficiency, many Led manufacturers have tried their best to solve this problem in recent years. There are two ways to solve this problem. One way is to find a better thermal energy transfer substrate board instead of Alumina, such as an aluminum nitride substrate, silicon carbide substrate, anodized aluminum substrate, or Silicon substrate. The silicon carbide substrate and Silicon substrate, Material with semiconductor properties, make applying difficult. In addition, the anodized aluminum substrate is too easy to break, making it hard to use. At present, the Aluminum Nitride application is the most mature.

    The thin-film process of Aluminum Nitride can enhance the heat energy transfer from Led die to substrate to system PCB efficiency.

    The other way of handling thermal energy evacuation is complicated Led die and substrate in eutectic or flip-chip. It would improve the efficiency of the thermal energy transfer electrode lead to the PCB. But it strictly requests substrate wire accuracy and surface smoothness. Because the sintering shrinkage and screen opening process affects the accuracy of thick film and low-temperature burn ceramic, it is unsuitable for use.

    At present usually use thin-film ceramic substrate to solve this problem. The thin-film ceramic substrate uses light yellow lithography to make the circuit PCB. It uses chemical plating or electroplating to increase the thickness of the wire, which makes out PCB with high accuracy wiring and smooth surface. Eutectic and flip-hip use of the thin-film ceramic substrate should enhance the Led bulb’s work life and lighting power.

    Because the aluminum PCB developed so well, the Led bulb’s thermal energy transfer problem has been significantly improved, even developing trends to the flexible PCB. Besides, the Led die substrate board, also develops a low thermal resistance trend.

    The most crucial subject is reducing the thermal resistance of Led ceramic thermal evacuating substrates to enhance the Led luminous efficiency. Classified by wiring bonding, they can be separated into thin-film ceramic substrate boards, low-temperature co-burned multilayer ceramic boards, and thick-film ceramic substrate boards.

    In recent years thin-film ceramic substrate boards have been widely used as Led die-evacuating energy heat substrates. They can solve the thick-film process screen opening problem and the problem of shrinkage ratio after multi-layer sintering and lamination. Thin-film heat-dissipation substrates board are manufactured by yellow light lithography, electro/electrochemical deposition and sputtering. Its feature below:

    • Under low temperature(below 300℃) process, it can avoid.
    • Dimensional change and material damage by high temperature.
    • Higher accurate substrate can be made out.
    • It can prevent the metal wire from falling off.

    With those advantages, a thin film ceramic substrate board is the best material to make a highly bright, small-size, high-power Led bulb suitable for highly accurate flip chip and eutectic processes.

    Low-temperature process technical is an excellent way to form multilayer ceramic substrate. Ceramics is the core of the PCB substrate material on the surface of PCB printing screen printing. But the wiring on the low-temperature multilayer is also printing out, so it still affects by mesh opening, rerror hard to avoid. Moreover, in this technical, the shrinkage problem still exists. So it would need a higher standard if using the low-temperature co-fired multilayer ceramics to make out specific circuit alignment eutectic/flip chip Led products.

    Screen printing technology is the primary technique used to produce Thick-film ceramic substrates. Materials are printed on the substrate with a squeegee and are made through drying, sintering, laser and other steps.

    The screen printing technology makes out the line usually needs to be more accurate. Therefore, for high-power LED products with smaller and smaller size requirements and finer and finer circuits in the future, or LED products produced by eutectic or flip-chip processes requiring accurate alignment, the accuracy of thick-film ceramic substrates It is gradually running out of use.

    LED PCB Design

    A schematic diagram can start the Led circuit board design process. After you have the schematic, you should proceed with other steps, such as the component layout and Parameter setting. The LED PCB board wiring is a vital aspect to consider. It can be tricky if you don’tdon’t have experience in Led circuit board wiring.

    Schematic Diagram of the LED PCB Design Process

    Before starting the LED PCB design process, create a Schematic diagram. This design is the basis for the PCB design, so mistakes in the schematic diagram can cause errors in the final PCB. You should follow specific rules and guidelines when drawing a schematic diagram to get a great result. Here are a few tips to make the entire process run smoothly.

    First, use the Schematic Diagram Tool.

    Next, you must ensure your schematic diagram follows the same logic as your circuit. It will make it easier for you to read the circuits and make the design more readable. Make sure the connections are logically separated using global symbols instead of considerable power and ground lines. Try to avoid creating complex circuits that have multiple connections in one diagram. This way, you can quickly troubleshoot your circuit.

    What is Led Driver PCB?

    To understand how this circuit works, let’slet’s first discuss some of the characteristics of Led drivers—led connect with AC Power through Led driver. They convert incoming AC power into DC output current and are available in wide varieties. The most common are buck-boost and flyback.

    The Led-driven output line usually comprises a positive red and black negative pole. The other lines are coloured grey, white, and blue-brown. The Led also connects the positive and negative lines on an Led driver PCB. The Led-driven output line is connected to a positive supply voltage through a pin on the board, while the negative and ground connections connect to the other two pins.

    EMI (electromagnetic compatibility) refers to the ability of Led drivers to function in an electromagnetic environment without disturbing adjacent equipment. Good EMI design means the Led driver is compatible with various electrical and electronic components. The THD value is a percentage and is crucial because it can lead to issues with power distribution equipment. If THD is too high, the Led driver will not work correctly or may even lead to electrical shock.

    LEDs have several advantages over other lighting sources, including low power consumption, fast turn-on time, and low heat generation. However, a vital issue with LEDs is that their driver must be cost-effective. Discrete Led drivers are not very cost-effective, but an integrated Led driver may be better for your Led lighting system. So, which one is the best?

    A constant-current Led driver is characterized by a voltage stabilizer that allows it to operate without a load-short circuit. A regulated drive circuit also depicts it, and each Led string is fitted with a resistor based on the average brightness of a resistor. The Feedback voltage is a considered factor in adjusting Led string voltage, and the voltage determines the brightness of Led. Several layers of LEDs are connected to an Led driver. Led drivers can operate several Led modules in parallel or series. A constant current driver must also withstand power dissipation when the load is short-circuited, as it would result in a short circuit.

    Types of LED PCB

    Hybrid LED PCBs are printed circuit boards (PCBs) that utilize a combination of light-emitting diodes (LEDs), which are used to produce various colours and effects, as well as other components like resistors and capacitors. Hybrid Led circuit boards can be used in multiple applications – from automotive lighting to consumer electronics – making them an attractive choice for many industries. The advantages of Hybrid LED PCB boards are mainly stated below.

    • Low power consumption
    • Long life span
    • High brightness levels
    • More efficient thermal management

    With the proper design considerations, hybrid Leds can provide superior performance while reducing costs significantly. As a result, hybrid LED PCBs are becoming increasingly popular due to their many advantages, making them an ideal choice for many applications.

    Single-sided LED PCBs are circuit boards that provide a simple and cost-effective way to utilize LEDs in various applications. Single-sided LED PCB boards consist of one layer of copper foil, which is etched with the desired circuitry and then laminated onto an insulating substrate. Single-sided Led circuit boards are ideal for lighting systems, automotive components, medical instruments, smart home devices, communication equipment and more. They can be designed to fit any application requirement with features such as high-speed signal routing or custom mounting options.

    Many types of Led need to be bent or twisted when under use. So the normal Led made with rigid PCB can’t meet this request. So, in this case, the flexible LED PCB was developed.

    One of the essential features of a board is its flexibility. It allows you to create different design solutions for your board. In addition, you can save money by not having to spend a lot of money on creating other circuit boards.

    If you are looking for a Led board that can be used in harsh environmental conditions, such as in hazardous areas, then the flexible Led board is the one for you.

    A Led made of flexible PCB would be sound-in, waterproof or shockproof, giving the Led higher survival ability when working in harsh environments.

    It will be a good idea if you want to create a multi-layer Led circuit board. This type of board can provide you with the kind of efficiency that you need. This type of board design involves multiple layers of insulating materials being stuck between them.

    Each layer has unique electrical properties, and several layers combine to be a Led board, improving the LED PCB performance. On the other hand, the insulating materials used on the board can prevent the melting of the Led components.

    Unlike the flexible Led circuit board, which can be bent, rigid LED PCBs are not designed to be bent. Instead, they are made with solid materials that prevent them from being twisted or turned in different directions. It is the main reason they cannot be used for other applications.

    Despite the disadvantages of having a rigid Led board, it is still essential to consider using it in specific applications. For instance, a rigid Led board is the best choice to create a circuit board that doesn’t change its original design.

    According to the number of rigid PCB layers, rigid PCB can also be classified into single-layer Rigid PCB, double-layer Rigid PCB, and multi-layer rigid PCB.

    Why Is Aluminum Popular in LED PCB?

    The Benefits of Using Aluminum to Make LED PCB

It helps to prevent external temperatures from becoming too high, damaging the components, or even causing the board to catch fire.

    Improved performance

    Using aluminum in LED PCB boards offers many advantages in terms of improved performance. Aluminum has a high thermal conductivity, which helps dissipate heat away from the circuit board quickly, allowing for more efficient operation and lower power consumption. Additionally, aluminum is less susceptible to oxidation than other metals, making it highly resilient and reliable. It makes aluminum an ideal choice for Led circuit boards that require high performance and reliability in even the most demanding environments.


    LED PCBs made from aluminum to have several advantages, particularly in terms of cost-efficiency. Aluminum is an abundant resource, meaning it is relatively inexpensive to acquire for manufacturing. It makes LED PCBs made from aluminum much more affordable than those made from other materials such as copper or gold. So aluminum material are widely accepted by LED PCB manufacturer and LED PCB user.

    Easier soldering

    LED PCB boards made of aluminum offer many advantages when it comes to soldering. The metal is known for its low electrical resistance, meaning less heat must be applied during the soldering process, which makes it easier to solder components onto the PCB and also reduces the risk of damaging delicate electrical components.
