- Alumina or aluminum oxide (Al2O3) is a compound of aluminum metal and oxygen usually used in the alpha alumina structural form. In its pure form alumina is a white, high hardness ceramic. Fully dense alumina can be translucent. Alumina has found wide application due to its versatility and a relatively low raw material cost.
- Depending on the purity and density, alumina is used for refractory tubes, industrial crucibles, analytical labware, dielectric substrates, wear components, refractory cements and abrasives. Alumina's main drawback is its relatively poor thermal shock resistance due its higher coefficients of thermal expansion and lower thermal conductivity compared to other pure ceramic materials such as SiC.
- Alumina is an advanced ceramic material that possesses several good properties including mechanical, thermal, electrical and chemical properties. Therefore, it is used as different kinds of products such as milling ball, milling vial liner, spark plug insulator, crucible, sand blast tube and electronic substrate. The industries involving alumina are very important basic industries for the development of other domestic industries.
- A raw aluminum blank substrate is machined for edge and surface preparation prior to nickel alloy plating. This process sets the ultra smooth surface finish for the aluminum substrates as well as critical edge chamfer design points. The substrates are annealed to relieve stress in the material as well as temper the parts for the next steps in the process.
- A modified Ziegler alcohol process produces high purity gels, derived from aluminum metal. This manufacturing process for these products begins with primary aluminum to produce an alumina of extraordinary purity.Currently, alumina (Al2O3), glass and glass ceramics are used to manufacture substrates. These materials, however, do not possess the increasing property demands like high thermal conductivity and compatible CTE.
- This high grade alumina substrate has good features made by an application of its own substrate manufacturing techniques.This substrate is also available as processed substrate, having via-halls and / or grooves.
- It has the features of Excellent surface roughness, High bending strength, High purity, Better density, Good electric features, Capable of offering substrate in thickness as thin as 0.1mm
- The aluminum substrate’s thermal conductivity (the ability to dissipate heat) is characterized at 173W/m-K — far superior to other types of traditional substrates (0.8W/m-K for FR4 PC board; 17.3W/m-K for 304 stainless steel; or 21W/m-K for 96% alumina ceramic). An aluminum alloy substrate consisting of either 3003 or 6061 aluminum delivers high thermal conductivity and low cost. Long term thermal shock testing confirms the ruggedness of the dielectric medium.
