How strong are the alumina ceramic plates commonly used in the electronics industry
In today's rapidly developing electronic industry, the application of high-performance materials is crucial for improving the performance and reliability of electronic products. Alumina ceramic plates have become a highly anticipated material in the electronics industry due to their excellent performance, and are widely used in multiple key fields.
Alumina ceramic plates are made of high-purity aluminum oxide and have outstanding high thermal conductivity, with a thermal conductivity coefficient of up to 24W/(m · k). This feature enables it to quickly dissipate the heat generated in the circuit, effectively reducing the operating temperature of the circuit and greatly improving its stability and reliability. For example, in high-power electronic devices, alumina ceramic plates can quickly dissipate heat, ensuring stable device operation and avoiding performance degradation or failure due to overheating.
At the same time, alumina ceramic plates have high insulation properties, with an insulation breakdown voltage of up to 15kV/mm, which can withstand high voltage and high current shocks, prevent circuit breakdown and short circuit faults, and provide solid guarantees for the safe operation of electronic devices. In electronic devices, reliable insulation performance is a key factor in ensuring the normal operation of circuits and avoiding signal interference.
Its high pressure resistance is also excellent, with a bending strength of 350MPa, which can withstand large mechanical stresses, ensuring the integrity and safety of the circuit in various environments. Whether it is slight vibrations that may occur in daily use or complex mechanical stresses in industrial environments, alumina ceramic plates can stably support circuits.
In addition, alumina ceramic plates also have high wear resistance, high temperature resistance (fire resistance temperature up to 1600 ° C), and high chemical corrosion resistance. High wear resistance enables it to resist external forces such as scratches, friction, and impact during long-term use, extending the service life of the circuit; High temperature resistance allows it to work normally in high-temperature environments and is suitable for various extreme conditions; Good acid and alkali resistance, as well as resistance to saltwater solutions, prevent the circuit from being corroded by chemical substances, and maintain the cleanliness and stability of the circuit.
Based on these outstanding properties, alumina ceramic plates are widely used in the electronics industry. It is an indispensable key material in the manufacturing of electronic components such as semiconductor devices and integrated circuits, effectively improving the performance and stability of electronic products. In the manufacturing of chip resistors, alumina ceramic substrates significantly improve circuit reliability and wiring density due to their small size, low thermal expansion coefficient, high reliability, and thermal conductivity, making them an ideal carrier material for chip resistor components.
In the field of hybrid integrated circuits, alumina ceramic substrates provide support for complex circuits by carrying metal conductors and dielectric materials through thick film or thin film processes, with 99% of alumina ceramic substrates being the most commonly used.
For power device packaging, alumina ceramic substrates are widely used due to their excellent thermal conductivity, insulation, heat resistance, and voltage resistance. For example, DBC and DPC technologies have become the preferred materials, and products with 99% aluminum oxide content are particularly common.
In high-power LED heat dissipation solutions, alumina ceramic substrates also perform well, with efficient heat dissipation performance and excellent airtightness, not only improving LED luminous efficiency and lifespan, but also ensuring its weather resistance in different environments, becoming an indispensable part of the LED packaging field.
With the continuous advancement of technology, the electronic industry has increasingly high requirements for material performance. With its excellent performance, alumina ceramic plates will have a broader application prospect in the electronic industry, which is expected to promote electronic technology to new heights and inject new vitality into the industry's development.
