Ceramic Substrate Manufacturing Process

Material Selection
The first step in the manufacturing process is selecting the appropriate ceramic material for the substrate.

Powder Preparation
The selected ceramic material is usually in the form of a powder. The powder preparation involves several stages, including grinding, mixing, and blending.

Forming
The ceramic powder is transformed into a green body through various forming techniques.

Drying
After forming, the green bodies undergo a drying process to remove the excess moisture and improve their strength.

Firing
The dried green bodies are subjected to a high-temperature firing process called sintering. Sintering involves heating the green bodies to a temperature below the melting point of the ceramic material.

Machining
Once the ceramic substrates are sintered, they undergo various machining processes to achieve the desired dimensions and surface finish. This may include cutting, grinding, drilling, and polishing.

Surface Treatment
To enhance the performance and compatibility of the ceramic substrates, surface treatments are applied. This can involve coatings, such as metal or dielectric layers, to improve electrical conductivity or insulation.

FAQ

Q: What is a ceramic substrate?

A: Ceramic substrates are basic materials used to carry electronic components and circuits. They are usually made of ceramic materials such as aluminum oxide and aluminum nitride, and have excellent thermal conductivity and electrical insulation properties.

Q: What factors need to be considered when using ceramic substrates?

A: Consider thermal expansion mismatch with other components, ensure good electrical insulation, pay attention to mechanical stress, and the specific operating conditions of the application. Also consider compatibility with bonding and sealing materials, and whether surface treatment or coating is required.

Q: What are the characteristics of alumina ceramic substrates?

A: Alumina ceramic substrates are one of the most commonly used types, with high mechanical strength, good electrical insulation, stable chemical properties, suitable for high temperature applications, and easy to obtain.

Q: What are the metallization processes on ceramic substrates?

A: Common metallization processes include direct bonded copper (DBC) and active metal brazing (AMB). DBC can directly connect copper to the substrate without additional materials; AMB requires brazing copper to the ceramic plate through active metal.

Q: What are the most important performance considerations when designing a new ceramic substrate?

A: This depends on the end application of the product. Ceramics are chemically inert and resistant to corrosion, moisture and high temperatures. When designing a new substrate, electrical, thermal and mechanical properties are equally important. Dielectric strength is an important factor in meeting isolation requirements and needs to be set according to the standards, specifications and regulations of the target application.

Q: How to choose a suitable ceramic substrate?

A: First, we need to understand the heat dissipation requirements of power semiconductor devices, and then calculate the required substrate thermal resistance based on the chip and ambient temperature. However, the combination of copper and ceramics does not always achieve the ideal thermal resistance.
