Advantages of Alumina Metalized Substrate


1. The thermal expansion coefficient of DBC DPC alumina metalized substrates is close to that of silicon chips, eliminating the need for transition layers such as Mo sheets, thereby reducing material and processing costs.

2. DBC DPC alumina ceramic substrates reduce the number of solder layers, simplify packaging and assembly, lower thermal resistance, minimize voids, and enhance product yield.

3. Metalized alumina ceramic substrates exhibit excellent thermal conductivity and high current-carrying capacity, enabling compact chip packaging, significantly increasing power density, and improving the reliability of systems and devices.


Applications of Alumina Metalized Substrate

Alumina metalized substratess can be applied in automotive electronics, aerospace, solar panel arrays, communication equipment, laser devices, and other fields.

It serves not only as carrier plates to support components but also function as heat dissipation and insulation materials. Additionally, they enable interlayer circuit interconnection, achieving superior electrical performance. They are widely used in automotive electronics, sensors, power modules, high-frequency switching power supplies, relays, communication modules, LED modules, and other applications.

Usage Instructions


1. Metalized alumina ceramic substrates should avoid prolonged exposure to high-temperature environments and contact with organic solvents to prevent performance degradation.

2. Before use, inspect the surface of the substrate for scratches, cracks, or other defects and only use it after confirming its integrity.

3. Ensure proper connection of the metalized alumina ceramic substrate to the power source and correct grounding to prevent electrostatic damage to the substrate.
