Ceramic Packages For Semiconductor Discrete Device Power Electronics

By -

Innovacera develops ceramic packages and metal packaging shells to meet customer customized requirements. Innovacera’s factory has established robust capabilities in the research and development of ceramic and glass materials, tape casting for green ceramics, microwave/RF simulation, packaging technologies including the ceramic packaging shells/substrates, brazing/sealing, and surface treatment processes, offering customers comprehensive and integrated packaging solutions.

Ceramic Packages For Semiconductor Discrete Device Power Electronics

 

Innovacera offers ceramic packages for semiconductor discrete device power electronics by using ceramic-to-metal sealing technologies. Ceramic packages adopt a ceramic sidewall structure instead of the traditional bead-type insulated ceramic design, significantly improving the voltage withstand performance of the housing. Copper-cored kovar lead pins and WCu heat sinks are bonded onto multilayer alumina ceramic packages or aluminium nitride ceramic packages. It is primarily used for encapsulating high-power transistors, diodes, triodes, and power modules.

Boron Nitride ceramic (BN)   with various applications, stands out as a versatile and high-performance compound in advanced materials. From its low thermal expansion excellent heat resistance outstanding electrical insulation and high wet resistance to molten metals,  boron nitride has found its way into various industries, including electronics, high-temperature furnace construction, ceramic manufacturing, semiconductor industry, aerospace, and now the realm of Physical Vapor Deposition (PVD) coating technology.   PVD coating is a process used to produce thin films or coatings on various substrates by evaporating and condensing a material in a vacuum environment. This technique is widely employed in automotive and optics industries, where thin films of metals, ceramics, or other materials are deposited onto surfaces to enhance their properties such as wear resistance, corrosion resistance, or aesthetic appeal.   Boron Nitride Ceramic has emerged as a game-chang...
