3.4 Mounting
3.4.1 Whistle
The Whistle was designed for mounting on a printed circuit board (PCB) via 2 mm pitch 0.51
mm square pins. When integrating the Whistle 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 Whistle be soldered directly to the board. Alternatively, though this is
not recommended, the Whistle can be attached to socket connectors mounted on the PCB. If
the PCB is enclosed in a metal chassis, we recommend that the Whistle be screw-mounted to
it as well to help with heat dissipation. The Whistle has screw-mount holes on each corner of
the heatsink for this purpose – see below.
