Typical Beam Pattern
Lamina’s BL-4000 LED arrays project a 125º (2θ1/2, 50% of peak value) Lambertian radiation pattern. Narrower beam distributions can
be produced by use of selected popular LED optics. Please contact Lamina Application Engineering for support with your optical needs.

Electrical Connections
Lamina’s BL-4000 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 solder pads. For more information
refer to Lamina’s Attachment application note which can be found on the website, www.LaminaCeramics.com.
Unlike the other BL-4000s, Lamina’s BL-42D2-0344 is designed for low voltage (4.3V) portable applications and is not designed
with an isolated base. The base may be conductive with the cathode (V-) terminal
Lamina has developed EZConnect PCB adapters with connectors for BL-4000 products for ease of assembly.
