Typical Customer Cases
Due to the power density of the RF module in a portable MRI device being increased to 20W/cm³, the traditional FR4 substrate (with a thermal conductivity of 0.3W/m·K) results in the chip junction temperature reaching 150℃ and thermal expansion mismatch causes solder joint cracking.
  • Material Innovation: Adopt aluminum nitride (AlN) substrates with a thermal conductivity of 170W/m·K (567 times that of FR4) and a coefficient of thermal expansion (CTE) of 4.5ppm/℃. It is highly matched with silicon chips (3ppm/℃), fundamentally solving the thermal mismatch problem.
  • Process Optimization: Achieve metallurgical bonding between ceramics and copper layers through the direct bonded copper (DBC) process, with an interface thermal resistance < 0.5℃·cm²/W. Combine with copper pillar array design to form vertical heat conduction channels, reducing the total thermal resistance to 0.15℃/W.
  • Reliability Assurance: Use active metal brazing (AMB) to enhance thermal shock resistance. After 1000 cycles of testing at -55℃~150℃, the solder joint strength retention rate is > 95%.
  • Results: The chip junction temperature is reduced to 85℃ and the power density reaches 22W/cm³. The product has passed ISO 13485 medical certification, meeting the device's 10-year service life requirement.

Customer Reviews

Authentic feedback from clients, validating our product quality and service level.

"Our industrial power modules operate long-term in high-temperature environments above 150℃. Previously, using ordinary PCBs led to frequent thermal failures. After switching to ceramic-based PCBs, the thermal conductivity efficiency has significantly improved. They've run continuously for 6 months with zero failures, and the device temperature has dropped by 28℃ compared to before. The stability has completely exceeded expectations—truly a reliable choice for high-power applications!"

—— Mark Reynolds, Senior Power Electronics Engineer

"The core heat dissipation area of our high-end projectors has long been limited by space constraints. The thin and lightweight properties of ceramic-based PCBs perfectly fit the product design: despite a thickness of only 0.6mm, they quickly conduct heat away from the chip. This allows the projector to operate continuously for 3 hours while keeping the body temperature below 45℃. User feedback indicates a significant improvement in experience, with the repair rate dropping by 35%."

—— Emily Carter, RF Systems Engineer

"When selecting a substrate for our automotive radar module, we compared multiple options and ultimately chose ceramic-based PCBs. Not only can they withstand vibration and impact during vehicle operation, but signal transmission remains stable within the wide temperature range of -40℃ to 125℃. After 1,000 thermal cycle tests, there was no cracking or desoldering whatsoever—fully meeting automotive-grade reliability requirements."
