SANTA CLARA, Calif., Jan. 24 /PRNewswire/ -- sp3 Diamond Technologies,
Inc., a leading supplier of diamond film products, equipment and services,
announced that testing has demonstrated the feasibility of its DiaTherm(TM)
Diamond Heat Spreaders for laser packages and LED devices. The decrease in
device junction temperature achieved by the increased thermal conductivity of
DiaTherm allows manufacturers to design improved device reliability margin or
longer lifetime with increasing laser and LED optical power by up to 300
percent.
DiaTherm offers thermal conductivity three times that of copper, a common
heat sink, and five times greater than aluminum nitride (AlN) or beryllium
oxide (BeO), common heat spreaders. These values equate to higher brightness,
closer spacing and longer lifetimes for LED devices and higher laser power
with the same device reliability.
"We have seen significant performance increases when DiaTherm is used as a
device's heat spreader," stated Dwain Aidala, president and COO of sp3 Diamond
Technologies, Inc. "Whether the designer uses this thermal benefit for longer
life, higher brightness, higher output power or a combination, the end result
is a cost effective material that provides differentiating capability to the
end product. This is a key message to both the design and marketing
communities."
Replacement of copper heat-spreaders used in bright LED devices with
DiaTherm enables an increase in LED optical power output of over 200 percent
at the same junction temperature. DiaTherm fits directly in LED device
assembly processing with solder attachment to the LED die and PCB or heat
sink. Cost increase for replacement of copper heat-spreaders with DiaTherm is
relatively small as the CVD diamond heat-spreaders have an unmetallized price
of about $1.5 per cubic millimeter.
"These results demonstrate how cost effective diamond can be as a heat
spreading technology. A diamond heat spreader represents only one to two
percent of the total bill-of-materials for laser packages, but its performance
offers benefits that far outweigh the cost. DiaTherm enables these devices to
operate at 300 percent greater optical power with the same reliability than
devices using traditional AlN or BeO heat-spreaders," continued Aidala.
Available as bare, freestanding diamond segments or in metallized form,
sp3's DiaTherm heat spreaders are laser cut from sheets of pure diamond formed
by chemical vapor deposition in DC torch reactors. DiaTherm is 100 percent
polycrystalline diamond with a density of 3.5 g/cubic cm. The material
achieves a thermal conductivity of up to 1400 W/m-k. In addition to its heat
conductivity, electrical insulating properties and ability to be machined to
tight tolerances, diamond is a passive heat spreader consuming no power.
