In the era when data is king, the PCB industry must also be able to keep up, and ceramic circuit boards must also be constantly updated and upgraded to keep up with the pace of the industrial revolution. With the expansion of LED downstream applications and the increase in market penetration, emerging markets such as high-value-added lighting, small-pitch displays, and automotive LEDs will bring incremental space to the industry. Driven by factors such as the expansion of production passivation in midstream packaging factories and the expansion of downstream application demand, it is speculated that LED prices are expected to rise or heat up in the future.

LED is a semiconductor device that can convert electrical energy into light energy. It has the advantages of energy saving, environmental protection, safety, long life, and low power consumption. From the perspective of the industry chain, LED mainly includes upstream chip manufacturing, midstream packaging and downstream applications. Among them, downstream LED applications are mainly divided into fields such as lighting, display, backlighting, decoration, and automotive lighting. The application of LED ceramic circuit board is an important link with high added value in the entire industry chain.

Although ceramic circuit boards are no longer a new product, their application in China has just begun. However, compared with other PCBs, ceramic circuit boards are a substitute for the older generation of substrates and can completely replace metal substrates and transparent substrates. Due to the characteristics of high thermal conductivity, high insulation, and better thermal expansion matching coefficient, it is more popular in the field of high-power lighting. Moreover, the ceramic circuit board industry has been developing for many years and has matured. At present, the overall market structure is also very clear. The continuous influx of small and medium manufacturers is sufficient to explain its market prospects.

In order to improve the luminous efficiency and lifespan of LEDs, solving the heat dissipation problem of LED products is one of the most important issues at this stage. Providing ceramic circuit boards with high heat dissipation and precision dimensions to dissipate heat has also become a trend in the future development of LED heat dissipation substrates at this stage.

Ceramic circuit boards improve the luminous efficiency of LEDs by means of aluminum nitride substrates and alumina substrates, which has become the mainstream of development. Under this development trend, the heat dissipation substrate itself has extremely strict requirements for line positioning accuracy, requiring high heat dissipation, small size, and strong bonding force of metal lines. Therefore, it has become an important path for using laser technology to promote high output of LEDs.

At present, the largest market for ceramic circuit boards in LED downstream applications is in the field of lighting, followed by backlight applications and displays. Among them, the scale of display applications is growing steadily. Especially with the maturity of small-pitch LED display technology, the application of ceramic circuit boards has gradually expanded from large-scale outdoor displays to rapid expansion of indoor applications, which has further improved the entire downstream application of LED displays. The share in the industry chain.
