Products Description

Metallization Ceramics are advanced structural ceramics that achieve hermetic welding and electrical connections between ceramic and metal, or ceramic and alloy, by sintering a metallized layer onto the surface of a high-performance ceramic substrate. Widely used in new energy, power semiconductors, aerospace and military applications, medical imaging, laser modules, high-voltage power devices, and other fields, they are an irreplaceable key material for achieving high-power density, high-voltage withstand, and high-reliability packaging.

As a direct-from-OEM metallized ceramic manufacturer, we possess a complete production line, from ceramic injection molding, metallization sintering, precision polishing, electroplating, to finished product testing. We offer customized support across multiple specifications and processes to meet the design requirements of diverse end-use packaging systems.

Full-process manufacturing capabilities ensure stable and consistent delivery

As an original equipment manufacturer with independent intellectual property rights, we offer a comprehensive manufacturing system that encompasses everything from the ceramic substrate to the metallization layer, including fine grinding, plating, and final packaging. This enables the construction of highly consistent, efficient, and clean ceramic packaging production lines. Specific manufacturing advantages include:

In-house molding of the ceramic body: Both alumina and aluminum nitride substrates utilize high-purity raw powders, formed by dry pressing or tape casting, achieving a secondary sintering density exceeding 98%.

Advanced metallization technology: We utilize state-of-the-art Mo-Mn sintering lines and continuous tunnel kilns. Combined with a controlled hydrogen reduction atmosphere, we ensure a dense metallization layer with strong adhesion.

High-precision grinding and pattern processing: We utilize precision CNC grinders and laser trimming systems to meet diverse and complex customer designs.

Professional and reliable coating processing: We utilize automated electroplating lines that support a range of coatings (Ni/Ag/Au), offering customized conductivity and weldability.

Strict quality control: We are equipped with specialized equipment such as a three-dimensional coordinate measuring machine, roughness tester, airtightness tester, micrometallographic analyzer, and adhesion tester to ensure traceability and complete documentation of test data for each Metallized Ceramics.

Every metallized ceramic component we ship undergoes rigorous quality control across multiple dimensions, including dimensional inspection, electrical performance testing, airtightness testing, adhesion testing, and visual inspection, ensuring that every metallized ceramic delivered to our customers is stable, reliable, and offers excellent performance.

Production Technology and Application of Metallization Ceramic

Applicable Applications and Industry Value

Metalized ceramics offer irreplaceable structural and functional value in the new energy and high-reliability electronics sectors, and are widely used in the following applications:

Power semiconductor packaging: such as SiC MOSFET modules, IGBT modules, and power converter device substrates;

New energy vehicles: Insulation support and heat dissipation substrates for OBCs, DC-DCs, and electric drive modules;

High-voltage power systems: High-insulation sealed structures for power capacitors, high-voltage fuses, and smart circuit breakers;

Industrial lasers and communications devices: Laser packaging housings, optocouplers, TO packages, and other high-sealing applications;

Military/aerospace electronics: Sealed ceramic interface components for extreme environments, such as radar components and satellite electronic modules.

Due to their high airtightness, high reliability, and high process stability, metallized ceramics are gradually replacing traditional plastic or glass encapsulation processes, becoming a core material for next-generation high-density, high-voltage packaging solutions.
