Ceramic-to-Metal Seal The Ceramic Surfaces for Brazing, the surface must be metallized. Compare to Glass seal, Ceramic seal has exceptional resistance to thermal and mechanical shock as well as corrosion. While it requires more complex manufacturing processes and sophisticated engineering, the price is obviously higher.

Mo Mn Ceramic Feedthrough Ceramic Vacuum Electrodes The Ceramic Surfaces for Brazing, the surface must be metallized. Compare to Glass seal, Ceramic seal has exceptional resistance to thermal and mechanical shock as well as corrosion. While it requires more complex manufacturing processes and sophisticated engineering, the price is obviously higher. Advantages of Ceramic-to-Metal Seals * More solid, durable hermetic seal and better electrical insulation * Used for more harsh conditions, such as high and low (cryogenic) temperature, corrosive, high pressure, and high vacuum environments * High mechanical strength, less fracture when applied to high vibration and high g-load conditions * Shows strong bond and an excellent seal with metals and alloys, such as copper and Cu alloys (CuNi) and to nickel and Ni alloys.

In a development that could have a significant impact on the electronics industry, the latest ceramic metallized insulators are making strides in enhancing semiconductor packaging and related applications. These insulators offer a range of practical benefits that can improve the performance and durability of electronic components. Let’s take a closer look at what sets them apart: Key Features of Ceramic Metallized Insulators: 1. Stability and Strength: The ceramic material employed in these insulators boasts an even texture, ensuring every batch maintains stable quality and flexural strength. This consistency in material quality is pivotal for the reliability of electronic components. 2.Dense and Weldable Metal Layer: The metal layers in these insulators are densely applied, providing a smooth and even surface. This not only enhances their appearance but also makes them easy to work with, particularly in manufacturing processes.

DBC ceramic substrate: Direct bonded copper (DBC) substrates are commonly used in power modules, because of their very good thermal conductivity. They are composed of a ceramic tile (commonly alumina) with a sheet of copper bonded to one or both sides by a high-temperature oxidation process (the copper and substrate are heated to a carefully controlled temperature in an atmosphere of nitrogen containing about 30 ppm of oxygen; under these conditions, a copper-oxygen eutectic forms which bonds successfully both to copper and the oxides used as substrates). The top copper layer can be preformed prior to firing or chemically etched using printed circuit board technology to form an electrical circuit, while the bottom copper layer is usually kept plain. The substrate is attached to a heat spreader by soldering the bottom copper layer to it. 1. Thickness of substrate can be thin: 0.25mm,0.28mm,0.45mm,0.5mm,0.635mm,1.0mm,1.5mm, 1.8mm,2.0mm 2.

High Hermeticity Metallized Ceramic Bushing /Innovacera Features: 1.Material: 96% Aluminia(AL2O3) 2.Coating Layer:Molybdenum-Mananese(Mo/Mn) 3.These metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos. So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing . A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different coefficient of thermal expansion. A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering. The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing.
