In recent years, with the miniaturization, lightweight design, and high performance of electronic devices, the importance of heat dissipation measures due to high-density mounting of electronic components has been increasing.
In particular, with high-brightness LEDs, it has become difficult to implement heat resistance measures with resin package specifications, making alumina ceramics materials indispensable for heat dissipation and heat resistance. Additionally, due to the recent increase in demand for ultraviolet LEDs, interest in ceramic packages has been rising. Our company offers ceramic package substrates with excellent heat resistance characteristics based on our unique technology. Our unique technology for "improving heat dissipation performance" has become increasingly important alongside the high brightness (high output) of LED elements, leading to a significant rise in the demand for heat resistance in packaging materials and heat dissipation characteristics. We have received many inquiries regarding "improving heat dissipation using a general-purpose alumina ceramics substrate compared to a heat-dissipating aluminum nitride substrate." By applying our unique printed circuit technology, we process through-holes in the alumina ceramics substrate and fill the through-hole sections with "special silver-based materials," achieving a higher heat dissipation effect than typical alumina ceramics substrates.
