Product Description

Electrical 0.385 mm/0.50 mm/0.635 mm/1 mm Alumina Ceramic Substrate for Circuit

Description of alumina ceramic substrate
Alumina (Al2O3) is one of the most cost-effective technical ceramics and extensively used ceramic substrate materials in microelectronic applications. 

96% alumina ceramic substrate is a kind of standard thick film substrates which is widely used in the manufacturing of hybrid microelectronic circuits. The availability, low cost, and technical quality of 96% alumina make it a cost-effective option for building hybrid devices. The substrates offer excellent electrical insulating properties, mechanical strength, good thermal conductivity, chemical durability, and dimensional stability.

We have been producing many selection thicknesses via tape-casting, the typical thickness includes 0.25mm, 0.385mm, 0.50mm, 0.635mm, 0.8mm, and 1mm thick.

The advantages of alumina ceramic substrate: 
1.High thermal conductivity, up to 24 W/m.k at 25℃                       
2.Good thermal shock resistance, greater than 220 T(℃)           
3.Good surface roughness, flatness to be 0.05mm
4.High dielectric strength, low dielectric constant, and dielectric loss.                       
5. Laser cutting or precision machining cutting makes tight tolerance.
Typical applications of alumina ceramic substrate:
LED packages, Power modules, Substrates for chip resistors, HIC substrates for heat dissipation, FAX substrates for thermal printer head, Substrates for automotive parts, Substrates for general thick film application, Substrates for sensor parts, Substrates for electronic devices
