Product Description

Industrial 96% Al2O3 Alumina Substrate Strip Long Ceramic Sheet

Product Description

Alumina (Al2O3) has a board range of applications due to its versatility and cost-effective advantage. It offers a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperatures and chemical corrosion.

We supply plenty of alumina substrates and sheets via tape casting, dry pressing, Isostatic pressing, and so on. All these industrial ceramic substrates are available in different dimensions, thicknesses, shapes and different grade of material.

FAQ

Q01: 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.
 

Q02: 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.

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.
