3.4.  Mounting 
3.4.1.  Hornet 
The Hornet was designed for mounting on a printed circuit board (PCB) via 2 mm pitch 0.51 
mm square pins. When integrating the Hornet into a device, be sure to leave about 1 cm (0.4") 
outward from the heatsink to enable free air convection around the drive. We recommend that 
the Hornet be soldered directly to the board. Alternatively, though this is not recommended, 
the Hornet can be attached to socket connectors mounted on the PCB. If the PCB is enclosed in 
a metal chassis, we recommend that the Hornet be screw-mounted to it as well to help with 
heat dissipation. The Hornet has screw-mount holes on each corner of the heatsink for this 
purpose – see below. 
Figure 3: The Hornet Footprint 
When the Hornet is not connected to a metal chassis, the application’s thermal profile may 
require a solution for heat dissipation due to insufficient air convection. In this case, we 
recommend that you connect an external heatsink. Elmo has an external heatsink (Catalog 
number: WHI-HEATSINK-2) that can be ordered for this purpose – see below.
