Product description
Characteristics of Aluminum Nitride Ceramic Substrate
(1) Superb high thermal conductivity, 6 times that of high purity alumina ceramic at least.
(2) The CTE ((4-6)×10-6/℃)) matches that of semiconductor silicon material (2.8×10-6/℃).
(3) Good mechanical properties, high flexural & compressive strength, close to high alumina.
(4) Excellent electrical properties, with extremely high insulation resistance and low dielectric loss.
(5) The compatibility of circuit materials is good, and multilayer wiring can be carried out to realize high density and miniaturization of packaging.
Our Manufacturing Capacity
Our rectangular shapes for as-fired aluminum nitride ceramic substrates are available up to 140mm×190mm.
The standard thickness is 0.38mm, 0.50mm, 0.635mm and 1.0mm.
For products that require high dimensional accuracy, we can use various processing methods to process ceramic substrates,
such as lapping, polishing, laser scribing, laser cutting, etc.
Besides AlN ceramic substrate, alumina ceramic substrate and si3n4 ceramic substrate are within our business scope,
these substrates could help our customers to settle their different needs.
