Product detail
Aluminum nitride ceramic substrate is a precision ceramic component used for LED ceramic base, LED package substrate, LED lamp bead base and electronic heat dissipation applications. It provides both high thermal conductivity and excellent electrical insulation, making it suitable for LED and electronic devices that require fast heat transfer and stable insulation performance.
In LED packages and compact electronic modules, heat management is important for brightness stability, service life and long-term reliability. AlN ceramic substrate can help conduct heat from the chip area to the external heat dissipation structure while keeping the circuit electrically insulated.
Compared with alumina ceramic, aluminum nitride ceramic offers much higher thermal conductivity. Mascera's AlN ceramic can reach thermal conductivity of ≥170 W/m·K, while maintaining low dielectric loss, good mechanical strength and stable dimensional performance. It is a reliable material choice for high-power LED lighting, LED package substrate, laser diode base, power module insulation and other heat-sensitive applications.
Mascera supplies customized aluminum nitride ceramic substrates according to customers's drawings or samples. Available forms include small ceramic substrates, ceramic spacers, square ceramic plates, rectangular ceramic bases, thin ceramic wafers and other special-shaped AlN ceramic components. The size, thickness, tolerance, flatness and surface finish can be customized according to different application requirements.

Alumina Ceramic vs Aluminum Nitride Ceramic For LED Bases
Alumina ceramic and aluminum nitride ceramic are both insulating ceramic materials used in electronic and LED applications. Alumina ceramic has good electrical insulation and lower material cost, making it suitable for general insulation parts and low to medium power applications.
Aluminum nitride ceramic is recommended when better heat dissipation is required. Its much higher thermal conductivity helps transfer heat away from the LED chip area more efficiently, making it suitable for LED package substrates, high-power LED ceramic bases, laser diode bases and other heat-sensitive electronic components.
