Improving thermal conductivity of alumina substrates with printed circuit technology [For mounting power devices!]
Leveraging the strengths of a "ceramics substrate specialized manufacturer," we have achieved "high thermal conductivity of alumina substrates" through via formation technology and printed circuit technology!
In the implementation of power devices, where applications are expanding in areas such as home appliances and EV vehicles, expectations for "thermal conductivity performance of the substrate" are rising significantly. Through the mass production achievements of our flagship high-power LED packages, we have developed technologies to improve heat dissipation performance associated with higher power output. In particular, we have received many inquiries regarding "improving thermal conductivity using general-purpose alumina ceramic substrates compared to aluminum nitride substrates, which excel in thermal conductivity" for ceramic circuit boards. We have achieved improvements in thermal conductivity by applying through-hole processing technology (via formation) and printed circuit technology, filling the via sections of alumina ceramic substrates with "metallic materials," while using general-purpose alumina ceramic substrates. For high-power LED package substrates, we have achieved a thermal conductivity of "369 W/mk" with alumina ceramic substrates. If you are facing challenges with "thermal measures" for ceramic substrate implementation of high-power power devices, please consult with us.
