3.
Place the LED on the thermal pad such that the hole patterns
match (Pre-drilled holes seen in Figure 10).
4.
Insert screws in the holes of the core
board and tighten. To ensure equal pressure is exerted by all screws,
alternate tightening each screw until the board is securely fastened. The use of a torque wrench, with a torque
setting of 40
ounce--inches (oz-in)
, is recommended.
Note : The heatsink described in this manual may change in later revisions, connections will be the same, and
thermal properties will be qualified by similarity.

recommendations
4.2 Additional Lab Equipment Needed By User
Additional lab equipment such as a 12 V or 24 V laboratory
power supply, an oscilloscope, a waveform generator, a
multimeter, and a photodetector are required to power and
evaluate the DK-236. Table 1 lists recommended models for
each of these pieces of equipment. The Lambda power
supplies recommended in Table 1 assume operation of one
device at a time.
4.3 Driver Board Operation
Arrange the evaluation kit, required lab power supplies, and
measurement
equipment
(e.g.,
digital
multimeters,
oscilloscope) preferably on one table. Refer to Figure 16 for
an example of the recommended equipment setup for
evaluation (no wire connections shown). It is also
recommended that the table has an ESD Protected Area
(hereafter referred to as "EPA"). Please refer to Appendix B for
ESD precautions.
