Ceramic pcb boards are many high-power packaging materials because of their high thermal conductivity, good insulation, low dielectric loss, and low thermal expansion coefficient. They are widely used in products such as semiconductor devices and power modules.
First, there are several materials for ceramic pcb boards
Ceramic PCB mainly has four core materials: alumina ceramic substrate, aluminum nitride ceramic substrate, silicon nitride ceramic substrate, and gallium nitride ceramic substrate. These four materials are made into alumina ceramic pcb board, aluminum nitride ceramic pcb board, silicon nitride ceramic pcb board, and gallium nitride ceramic pcb board. They are all insulating and thermally conductive materials, and their applications are slightly different. Aluminum nitride ceramic PCB has the highest thermal conductivity, and silicon nitride ceramic PCB has better strength.
Second, the difference between ceramic circuit boards and traditional PCBs, can ceramic substrates replace PCBs?
Ceramic circuit boards are ceramic PCBs, also known as ceramic substrates. They have significant heat dissipation and are different from traditional PCBs. Traditional PCBs conduct heat from 1W to 3W, and ceramic PCBs conduct heat from 15W to 170W. The heat conduction is more than ten times to hundreds of times that of traditional PCBs. . But the ceramic substrate is very good, but it may not be able to replace all PCBs. It is inevitable to replace it with a ceramic substrate that requires heat conduction but insufficient heat dissipation. Traditional PCB boards are used in many areas where the product requirements are not very high. The use of PCB can reduce the cost. After all, FR4 and ceramic substrate materials are relatively low in price and manufacturing technology.
Third, the purpose of pcb ceramic board? Where is the pcb ceramic board used?
PCB ceramic plates have many uses. PCB ceramic plates should be used in high-power power electronic modules, solar panel components, etc.; high-frequency switching power supplies, solid-state relays; automotive electronics, aerospace, and military electronics; high-power LED lighting products; communication antennas , Car ignition; insulation resistance ceramic pcb board; semiconductor devices; refrigeration equipment, etc.
Fourth, how much is the pcb ceramic board?
Ceramic pcb proofing
How much is the PCB ceramic board? This is indeed different from the PCB board. After all, the ceramic board is much more expensive than the FR4 board. Therefore, the price of the PCB ceramic board is much more expensive, which is basically more than three times that of the PCB. The price of ceramic PCB proofing is also different from the batch price. Naturally, the batch price is cheaper.
How to quote ceramic pcb
How to quote ceramic PCB, the specific quotation depends on the drawings, process requirements, strength and difficulty, including the utilization rate of the ceramic substrate. Generally speaking, aluminum nitride ceramic PCB is more expensive than alumina ceramic PCB, but the thermal conductivity is much better. The specific quotation is still subject to the evaluation of the provided information and documents.
