Quad Flat Package No Leads (QFN) Package
Design Notes
Electrical contact of the part to the Printed Circuit Board (PCB)
is made by soldering the leads on the bottom surface of the
package to the PCB. As a result, special attention is required to
the heat transfer area below the package to provide a good
thermal bond to the circuit board. A Copper (Cu) fill is to be
designed into the PCB as a thermal pad under the package. Heat
is transferred from the FX1 through the device’s metal paddle on
the bottom side of the package. Heat from here, is conducted to
the PCB at the thermal pad. It is then conducted from the thermal
pad to the PCB inner ground plane by a 5 x 5 array of via. A via
is a plated through hole in the PCB with a finished diameter of
13 mil. The QFN’s metal die paddle must be soldered to the
PCB’s thermal pad. Solder mask is placed on the board top side
over each via to resist solder flow into the via. The mask on the
top side also minimizes outgassing during the solder reflow
process.

the package. The cross section is of only one via. The solder
paste template needs to be designed to allow at least 50% solder
coverage. The thickness of the solder paste template must be
5 mil. It is recommended that ‘No Clean’ type 3 solder paste is
used for mounting the part. Nitrogen purge is recommended
during reflow.
