The application of alumina substrates in the automotive manufacturing industry
09-May-2023
Alumina substrate is the most widely, most economical and effective ceramic substrate material. It has good insulation, stable chemical properties, high thermal conductivity, good comprehensive performance. In the field of automobile industry, thanks to the rapid development of the industry, the demand for alumina ceramic substrates is increasing year by year.
The application of alumina substrates in the automotive manufacturing industry:
①IGBT packaging
IGBT is the leading device in modern power electronic devices. It is the third most representative product of the third revolutionary revolution in the world. In the traditional IGBT module, alumina substrate is the most commonly used precision ceramic substrate.
② Sensor chip packaging
Alumina ceramic substrate is heat-resistant, erosion, wear resistance, and its potential excellent electromagnetic and optical functions. In recent years, with the advancement of manufacturing technology, the sensors made of alumina ceramic materials can fully meet the above requirements. Represents the application include lidar, camera, millimeter wave radar, etc.
③ LED packaging
In recent years, LED lighting technology has been widely used in automobile manufacturing, such as headlights, taillights, indicators, etc., ambient lights, display backlights, etc. At present, the use of alumina ceramic substrates not only has low cost, but also can efficiently and environmentally friendly produce ceramic heat dissipation substrates for LED with high power, high precision, low cost, high adhesion and high surface flatness, so it has been widely used in the LEd field.
