Product Description

Alumina ceramic sheets are formed by tape casting, dry pressed or Isostatic pressed and sintered under high temperature to be a strong and dense ceramic part. We can produce different grades of materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies.

In order to reach some special applications, like enhancing the insulation strength, dielectric, and precision assembly, we always proceed with these ceramic alumina plates with the secondary process with our in-housing manufacturing types of equipment, including diamond polishing, glazed surface, high precision dimensions, and super flat surface and metalized.

Typical Applications

 

Remark:
Due to the ideal thermal conductivity,  coefficient of thermal expansion similar to Si and unmatched mechanical strength and corrosion resistance,  ceramic substrate is widely used in HIC, LED lights and power modules.

Product recommendation

 

Remark: 
Our facility supplies a large number of ceramic substrates, ceramic sheets, and ceramic plates in a selection of advanced ceramic materials, mainly including alumina (Al2o3), Zirconia (ZrO2), and Silicon nitride (Si3N4), Aluminum Nitride (AlN), and so on.

FAQ

Q01: What are the main advantages of a Ceramic PCB?

A: Maximum operating temperatures of the substrates of over 800°C, high Thermal Conductivity of up to 180W/mK, very low CTE (Coefficient of Thermal Expansion), 0% water absorption for Hermetic packages, low signal loss and fine microcircuit applications with the DPC production method.

Q02: What sizes are available for the Alumina substrates?
A: The typical largest size available is 280x240mm. Maximum standard thickness is 1.27mm and up to 2.0mm thicknesses are available per request. We offer customized products for special requirements.

Q03: What is the via diameter available for Alumina substrates?
A: Round vias with diameters of 0.2mm are available. Square holes and special shape holes are also available per request. Please contact us for details.

Q04: How are the ceramic substrates machined?
A: We use 100% laser processes. This is the best way to ensure precise and clean milling and drilling of the ceramic.

Q05: What other products do you manufacture?
A: Yes, we also produce metalized ceramics, ceramic seals and high precision pump plunger and pistons besides alumina ceramic substrates.
