UVLED sources can be used continuously for up to 20,000 hours or more. As LEDs emit more energy, they also generate more heat, which needs to be managed. Thermal management technology removes excess heat from the system, while providing a consistent and stable operating temperature for the diodes, ensuring optimal performance and extending the lifespan of the light.
To enhance the luminous efficiency and lifespan of LEDs, addressing the heat dissipation issue of LED products is one of the key challenges at present. The development of the LED industry is also focused on high-power, high-brightness, and compact-sized LED products. As a result, ceramic substrates with high thermal conductivity and precise dimensions are becoming a trend in the future development of LED heat sinks. Currently, replacing copper or aluminum substrates with ceramic substrates, or using eutectic or epitaxial processes to replace the gold wire bonding method for particle/substrate bonding, is the mainstream approach to improving LED luminous efficiency.
Under this trend, the alignment requirements for the circuitry of ceramic substrates are extremely stringent, and they must also possess high thermal conductivity, compact size, and excellent adhesion of metallic lines.
