As the market leader in the development and manufacture of super-bright LED
arrays, Lamina brings solid state lighting to applications which until now were
only possible with traditional lighting sources.
Lamina’s LED arrays are manufactured by combining high brightness LEDs from
industry-leading LED manufacturers with Lamina's proprietary packaging tech-
nology, multilayer Low Temperature Co-Fired Ceramic on Metal (LTCC-M). LTCC-M
is a breakthrough in thermal performance for LED packaging technology, a key
factor in determining LED life and reliability. Unmatched thermal performance
coupled with package interconnectivity allows Lamina to densely cluster multiple
LEDs to achieve exceptionally high luminous intensity in very small footprints.
Lamina’s arrays are available in white, RGB and monochrome, from 1W to
100W, and also are available in custom packages.
Lamina BL-2000 white LED arrays are configured with seven cavities, each popu-
lated with multiple LEDs. Multiple LED die in each cavity, a unique feature made
possible with Lamina’s packaging techology, assure Lamina light engines deliver
optimal color uniformity.
Lamina’s white 4300K LED light engines are designed with an enhanced spectral
distribution rich in red for applications demanding improved color rendition (90
typcial CRI) and warmer color temperatures.

ATTACHMENT
RECOMMENDATIONS
Lamina’s BL-2000 Series is
configured with solder pads
compatible with Sn63 or Sn62
solder. As with many electrical
devices, non-acid RMA type solder flux should be used to prepare the solder pads before
application of solder. If wire
attachment is performed with a
soldering iron, care must be
taken to minimize heat transfer
to the die and minimize leaching of the solderable pads.
ASSEMBLY
RECOMMENDATIONS
Lamina BL-2000 LED arrays
are designed for attachment to
heatsinks with conductive
epoxy or screw down for flange
mount devices with thermal
grease in the joint. In limited
cases, thermal transfer tape
can be used, but will generally
result in higher than desired
thermal resistance creating
excessive heat and reducing
light output and die life.

ECOMMENDATIONS
Lamina LED arrays provide efficient transfer of heat from the
individual LED die to a customer supplied heat sink. All
Lamina LED arrays must be
operated at or below 125ºC. A
heat sink must be attached to
the array with sufficient cooling
capacity to keep the die junction below 25ºC. The temperature rise from the array base to
the die junction may be determined by calculating the product of the maximum package
thermal resistance and the
desired operating power level.
The appropriate heat sink may
then be determined by:
O
PTICAL RECOMMENDATIONS
Lamina LED arrays project a
Lambertian radiation pattern,
with projection angles built into
the package cavity at approximately 125º. It will be necessary for users to create an optical reflector and lens structure
that meets their light dispersion requirements. Please contact Lamina Application
Engineering for support with
your optical needs.

IGHT OUTPUT VS

TEMPERATURE
Light output from LED die will
decrease with increasing junction temperature. This effect is
particularly acute for die in the
580 to 750 nm range. As a
result we recommend that the
LED array heat sink design be
optimized to maintain the die
junction temperature as low as
possible.
ESD PROTECTION
LEDs are static sensitive and
susceptible to Electrostatic
Discharge (ESD) damage.
Lamina LED arrays must be
handled using ESD damage
control precautions.
HANDLING PRECAUTION
Contact with the silicone based
encapsulant on the surface of
the light engine must be avoided to prevent damage. Do not
apply pressure to the silicone
based encapsulant or allow it to
come into contact with sharp
objects. Lamina LED arrays
must be handled from the
sides.
