Thermal Stability
Ceramic materials excel in high-temperature applications because they dissipate heat effectively and maintain structural stability under variable temperatures.
Insulation
Ceramic offers superb insulation, which means heat is less likely to pass through the substrate. This keeps the components on the circuit board safe from damage.
Inorganic Nature
Due to its inorganic composition, ceramic lasts longer and resists chemical erosion. This durability ensures functionality over extended periods without degradation.
Multi-Layering
Multi-layer ceramic PCBs enable more complex circuit designs. Ceramic’s robustness ensures the safety of other components even with the addition of layers.
Introduction to Ceramic PCB
If you’re working on demanding electronic applications that require high performance and reliability, consider using Ceramic PCBs. Unlike traditional boards made from fiberglass or epoxy, Ceramic PCBs use ceramic materials, offering unique properties and capabilities. They are suitable for environments that demand high thermal conductivity, high-frequency electrical performance, and durability in harsh conditions.
Because they handle higher temperatures and offer better thermal conductivity, Ceramic PCBs are ideal for power electronics, aerospace, and military applications. When you’re selecting a PCB fabricator, think about factors like cost, materials, and delivery time. At PCBAIR, we follow the latest IPC standards and DFM rules to ensure your next Ceramic PCB design meets your needs.
Ceramic PCB Manufacturing
Ceramic PCBs consist of a single ceramic substrate with copper layers applied to both the top and bottom. These copper layers are added through processes like sputtering, plating, sintering, or brazing.
Depending on the ceramic material you need, we offer AlN, alumina, SiC, Si₃N₄, BeO, and hybrid ceramic PCBs. We also provide different types based on the manufacturing process, including LTCC, HTCC, DPC, DBC, thick-film, thin-film, and AMB.
In our ceramic PCB fabrication process, we use two lamination methods to meet your specific requirements: normal lamination and sintering lamination.
In normal lamination, we bond two ceramic substrate layers under high temperature and pressure using a dielectric layer (PP), mainly composed of phenolic, epoxy resin, or specialized thermally conductive materials.
Sintering lamination, also performed under high temperature and pressure, causes the molecules at the contact surfaces of the two ceramic layers to migrate and fuse, forming a dense polycrystalline ceramic with a relative density exceeding 98%.
While normal lamination offers lower manufacturing costs, it significantly reduces the overall thermal conductivity of the ceramic circuit board, and its bonding strength isn’t as high as that of sintering lamination.
If your application demands high thermal conductivity and strong bonding strength, we recommend the sintering lamination method. This technique creates a strong and reliable bond between the copper and ceramic materials without affecting the ceramic substrate’s properties, especially its thermal conductivity and flatness.
Our team is ready to help you determine the best lamination method for your specific needs, ensuring that your ceramic PCBs meet all your performance requirements.
