usages of ceramic substrates

Ceramic substrates refers to a special substrates board in which copper foil is directly bonded to the surface of aluminum oxide (Al₂O₃) or aluminum nitride (AlN) ceramic substrate at high temperature. So, what do you know about the usages of ceramic substrates?
1. Application of ceramic PCB in chip

Ceramic substrates are often used in LED chips to achieve better thermal conductivity. In addition, ceramic substrates are often used in the following electronic devices to make ceramic chips:

a. High-power semiconductor modules.

b. Semiconductor refrigerators, electronic heaters; power control circuits, power hybrid circuits.

c. Intelligent power components; high frequency switching power supply, solid state relay.

d. Automotive electronics, aerospace and military electronic components.

e. Solar panel components; telecommunication private exchange, receiving system; laser and other industrial electronics.

2. Application of ceramic substrates in the third generation semiconductors

Mainstream power devices represented by MOSFET, IGBT, transistors occupy a place in their respective frequency and power supply power segments. Due to its comprehensive excellent performance, IGBT has replaced GTR and become the mainstream device in inverter, UPS, frequency converter, motor drive, high-power switching power supply, especially in the electric vehicles, high-speed railways and other power electronic devices.

3. Application of alumina ceramic substrate in electronic power field.

In the field of power electronics, such as power switching, power supply and electric drive, ceramic substrates dielectric are needed to achieve better thermal conductivity and prevent current burnout and short circuit.

4. Application of alumina ceramic co-fired substrate in lithium battery industry

With the development of artificial intelligence and environmental protection, the automobile industry has also launched electric cars, mainly through battery storage. Lithium batteries made of ceramic substrates can achieve better current and heat dissipation functions, and promote the market demand for new energy vehicles.

5. Application of ceramic substrates in integrated circuits

Small sized ceramic substrate chips (less than 3mm*3mm) can also realize the packaging of small sized integrated circuits through technology, so the application of integrated circuits is also growing; after all, the development of integrated circuits has the characteristics of precision and miniaturization.

The above is the purpose of the ceramic substrate, do you understand it?
