Aluminum Nitride Substrates & Components
Accuratus maintains an inventory of standard
aluminum nitride
substrates for fast delivery requirements. They are stocked in industry
standard thicknesses of .025 inches and .040 inches. We will
be
happy to provide a quotation. Call us at 908-213-7070 or fax
your
requirement to 908-213-7069. If you prefer, you can submit
your
RFQ on-line at the Aluminum Nitride
Request For Quotation page.

Substrates
Aluminum nitride substrates available from Accuratus are produced using
tape casting or dry pressing methods. Tape casting produces
sizes
up to 5 inches by 7 inches and .060 inches thick. Dry
pressing
produces substrates up to 2 inches square and .250 inches thick.
A list of standard substrate sizes can be found on the Aluminum Nitride Substrate Sizes
page. Standard aluminum nitride process methods yield strong
substrates with consistent material properties and
at least
170W/mK room temperature thermal conductivity. Specialized
methods can yield room temperature thermal concutivity of up to 230
W/mK although the mechanical strength is lower. Typical
material
properties for the standard stubstrates are found at the Aluminum Nitride Substrate
Characteristics page.
Our substrates are ready to use as-supplied or can be further
processed. They are compatible with mechanical dicing, laser
scribing and cutting, thick film hybrid metallizing, thick film
refractory metallizing, thin film metallizing and direct bond copper
processes.
Components
Accuratus
also offers isostatically pressed aluminum nitride components.
These are available with up to 2 inch cross section and 8
inch
length as bars, rods and tiles. Typically components are
precision machined after firing to meet customer dimensional
requirements. Typical material properties for the isopressed
product can be found at the Aluminum
Nitride page in the Materials section of the website.
