If you are looking for QFN soldering reflow details for the NRF52840-QIAA-F-R7 IC from Nordic Semiconductor, please refer to the details below.
The manufacturer recommends using the solder profile outlined in the “Solder Reflow Profile” for soldering QFN packages. However, factors such as circuit board thickness, component size, other semiconductor packages, passive components, and reflow equipment may affect the overall profile time.
Note:
• Package thickness < 2.5 mm and volume < 350 mm2.
• All temperatures refer to the center of the package, measured on the package body surface
that is facing up during assembly reflow (for example, live-bug).
• Actual board assembly profiles should be developed based on specific process needs and
board designs and should not exceed the parameters in this table.
