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/m°K room temperature thermal conductivity. Specialized
methods can yield room temperature thermal concutivity of up
to 200 W/m°K 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.
