Product Description
The BH006A0 aluminum nitride (AlN) thick film gold paste ceramic circuit board represents the cutting edge of ceramic substrate technology for advanced electronic applications. Aluminum nitride is a premier ceramic material known for its outstanding thermal conductivity — exceeding 170 W/m·K — combined with a coefficient of thermal expansion (CTE) closely matched to silicon, making it the substrate of choice for high-power semiconductor packaging and hybrid microelectronics.
Our thick film gold paste printing process deposits high-purity gold conductor traces directly onto the AlN substrate through precision screen printing, followed by high-temperature firing. This creates mechanically robust, chemically stable conductors that resist oxidation even at elevated temperatures. The gold conductors support gold wire bonding, a critical requirement for hermetic packaging in military, aerospace, and telecommunications applications where long-term reliability is essential.
The 2-layer design with through-hole vias enables more complex circuit routing compared to single-layer solutions. Via holes are metallized with gold or silver-palladium conductors, providing low-resistance vertical interconnects between the top and bottom circuit layers. This architecture supports higher component density and more sophisticated circuit functions while maintaining the superior thermal management of the AlN substrate.
At 1.0mm thickness, the BH006A0 strikes an optimal balance between mechanical strength and thermal performance. The board is suitable for direct attachment of bare semiconductor die, SMD components, and wire-bonded devices. Its compact form factor and excellent thermal characteristics make it ideal for space-constrained, high-power-density applications.
