3.4 Mounting
3.4.1 Butterfly
The Butterfly was designed for mounting on a printed circuit board (PCB). It is connected by
2mm pitch 0.51 mm square pins. When designing the Butterfly into a device, be sure to leave
about 1 cm (0.4") outward from the heatsink to enable free air convection around the Butterfly.
We recommend that the Butterfly be soldered directly to the board. Alternatively, the Butterfly
can be attached to socket connectors mounted on the PCB. If the PCB is enclosed in a metal
chassis, we recommend that the Butterfly be screw-mounted to it as well to help with heat
dissipation. The Butterfly has screw-mount holes on each corner of the heatsink for this
purpose.
3.4.2 Dragonfly
The Dragonfly was designed for mounting on a printed circuit board (PCB). It is connected by
2mm pitch 0.51 mm square pins. When designing the Dragonfly into a device, be sure to leave
about 1 cm (0.4") outward from the lower board to enable free air convection around the
Dragonfly. We recommend that the Dragonfly be soldered directly to the board. Alternatively,
the Dragonfly can be attached to socket connectors mounted on the PCB.
Note: Elmo recommends you leave approximately 1 cm (0.4 in) of space on the side opposite
the terminals to allow for free air convection.
