Lamina's BL Series Light
Engines are 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
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.

Lamina's BL Series Light
Engines, 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.
