What is ceramic PCB material?
Ceramic PCB materials are special materials, and ceramic PCB materials have good thermal conductivity and insulation properties. Ceramic PCB materials are inorganic materials, and the core of ceramic PCB materials is alumina or aluminum nitride。
The Difference between Ceramic PCB and PCB
1. Different materials. Ceramic PCB materials are inorganic materials, and the core of ceramic PCB materials is aluminum oxide or aluminum nitride; ordinary pcb boards use FR4 glass fiber boards, which are organic materials. Ceramic PCB materials and ceramic substrates are fragile and cannot be pressed together. Ordinary PCB boards can be laminated in multiple layers.
2. The required properties and applications of ceramic PCB materials are different. Ceramic substrates require special ceramic PCB materials, which are used in industries that require high heat dissipation, such as high-power LED lighting, high-power modules, high-frequency communications, track power supplies, etc. Ordinary PCB boards are widely used, mostly in private above commercial products.
The Difference between Ceramic PCB and High Frequency PCB
The difference between ceramic PCB and high-frequency PCB is that the materials of ceramic PCB and high-frequency PCB are different; the application fields of ceramic PCB and high-frequency PCB are different; the performance of ceramic PCB and high-frequency PCB is different; ceramic PCB and high-frequency PCB can be used in combination .
Classification of ceramic PCB materials
The classification of ceramic PCB materials mainly includes: alumina ceramic PCB material, aluminum nitride ceramic PCB material, silicon nitride ceramic PCB material and gallium nitride ceramic PCB material. Ceramic PCB materials are all insulating and heat-conducting materials.
Ceramic PCB material application
Ceramic PCB material application in the fields of electricity, electronics, electronic packaging, hybrid microelectronics and multi-chip modules; Ceramic PCB material application in refrigeration chips and systems, high-power modules, automotive electronics, high-frequency communications and other fields.
Advantages of ceramic PCB materials
Ceramic PCB materials have good high-frequency performance and electrical performance, and have high thermal conductivity, chemical stability and thermal stability. Ceramic PCB materials are ideal packaging materials for the production of large-scale integrated circuits and power electronic modules. Aluminum nitride ceramic pcb board has the highest thermal conductivity, and silicon nitride ceramic pcb has better strength.
