- 96% alumina ceramic / aluminum nitride ceramic
- customized as per required specification
- 100 pcs
- high power electronic modules
Ceramic PCBs have much beter heat dissipation performance, current-carrying capacity, electrical insulation, thermal expansion coefficient than ordinary glass fiber PCB board. Unlike ordinary PCBs, which use adhesives to bond copper foil and substrate together, ceramic PCBs are produced by bonding the copper foil and ceramic substrate directly in a high temperature environment. Ceramic PCBs have strong bonding force, copper foil will not fall off, leading to high reliability and stable performance under high temperature and high humidity environment. Ceramic PCBs are widely used in high-power electronic modules, aerospace, military electronics and other products.

Mascera is able to provide ceramic PCBs with alumina ceramic substrates and aluminum nitride substrates. Alumina ceramic is the most commonly used material for ceramic substrates which have good mechanical strength, heat resistance, impact resistance, electrical insulation and corrosion resistance. Because of the sufficient raw materials, affordable prices, and complete manufacturing and processing systems, alumina ceramic PCBs are the most cost-effective in the electronic packaging industry. Comparing with alumina ceramic substrate, aluminum nitride ceramic substrates have much higher thermal conductivity (7-10 times that of alumina ceramic), and its coefficient of thermal expansion (CTE) is close to that of silicon wafers, they are widely used in high-power semiconductor modules or large-scale integrated circuits.
Available Metallization Technology
Mascera develops two metallization technologies to produce ceramic PCB, one is DBC (direct bonding copper) and DPC (direct plating copper). DBC is suitable for circuits that line width and thickness are not critical, DPC is used to produce circuits that line size should be accurately controlled.
