Frequently Asked Questions
Alumina (Al2O3) is widely used for general high-temperature and insulation needs, while Aluminum Nitride (AlN) offers significantly higher thermal conductivity, making it ideal for extreme heat dissipation requirements.
Matching the CTE between the substrate and the attached components prevents mechanical stress and delamination during rapid temperature cycles, ensuring the circuit doesn't crack.
Yes, they are ideal for aerospace due to their high thermal stability, resistance to environmental degradation, and ability to operate in extreme temperature ranges.
They provide superior electrical insulation and a high dielectric constant, which prevents electrical arcing and short circuits in high-voltage environments.
LEDs generate significant heat at the junction. Ceramic PCBs move this heat away much faster than FR4, preventing lumen depreciation and increasing the LED's operational life.
Absolutely. The ceramic base is chemically inert, making these PCBs highly resistant to moisture, acids, and other corrosive agents found in industrial settings.
