Board Handling Instructions & Quick Start
When operating the evaluation board for the first time, please follow the procedure to ensure safe
handling and proper EVB usage.
Before board operation, refer to the EVB Operation Conditions Section to determine whether the fan/heat
sink assembly (hereby referred to as fan assembly) is required. If yes, install fan assembly to the back of the
EVB by removing the protective film from the thermal interface material, then proceed to insert the push-
pins through the mounting holes from the EVB backside. Plug fan connector into the fan socket on PCB
front side (Figure 2, block 4) to power the fan on.
In the instance that tests are to be conducted under conditions both with and without the fan assembly, it
is highly recommended to first conduct all non-fan assembly tests followed by higher power test with the
fan assembly installed, as the thermal interface material is difficult to remove.
