FAQ
Q: Do you have an office address that could be visited?
A: Our office address is Tianyue Building, Bao 'an District, Shenzhen.
Q: Will you attend the exhibition to show your products?
A: We are planning on it.
Q: How many specific materials are there for ceramic PCB boards?
A: There are four main core materials for ceramic PCB boards: alumina, aluminum nitride, silicon nitride, and gallium nitride. These materials are used to fabricate alumina ceramic PCB, aluminum nitride ceramic PCB, silicon nitride ceramic PCB, and gallium nitride ceramic PCB, respectively. Each of these materials is an insulating and thermally conductive material with slightly different applications. Aluminum nitride ceramic PCB have the highest thermal conductivity, while silicon nitride ceramic PCB offer better mechanical strength.
Q: What is the difference between ceramic circuit boards and traditional PCB? Can ceramic substrates replace PCB boards?
A: Ceramic circuit boards, also known as ceramic PCB or ceramic substrates, are distinguished by their superior heat dissipation properties compared to traditional PCB. Traditional PCB typically have a thermal conductivity of 1W to 3W, whereas ceramic PCB can range from 15W to 170W, which is ten to hundreds of times greater than that of traditional PCB. Although ceramic substrates are excellent, they may not replace all PCB. In applications requiring thermal conduction but not extensive heat dissipation, ceramic substrates are likely to be used. However, in many fields where traditional PCB do not demand high product specifications, using PCB can reduce costs. After all, the price and production process of FR4 and ceramic substrate materials are not comparable.
Q: What is the use of ceramic PCB? Where are ceramic PCB used?
A:ceramic PCB have a wide range of applications. They are used in high-power power electronic modules, solar panel components, high-frequency switching power supplies, solid-state relays, automotive electronics, aerospace, military electronic products, high-power LED lighting products, communication antennas, automotive ignition systems, insulation resistance ceramic PCB, semiconductor devices, and refrigeration equipment, among others.
Q: How long does it generally take to deliver HDI high-frequency PCB?
A: We have raw material inventory (such as RO4350B, RO4003C, etc.), and our fastest delivery time can be 3-5 days.
