For reflow soldering, it is recommended to follow the reflow profile in figure 6 as a guide, as well as the paste
manufacturers guidelines on peak flow temperature, soak times, time above liquidus and ramp rates.

A.3.2 Soldering Paste and Cleaning
NXP does not recommend use of a solder paste that requires the module and pcb assembly to be cleaned (rinsed in
water) for the following reasons:
Solder flux residues and water can be trapped by the pcb, can or components and result in short circuits.
The module label could be damaged or removed.
NXP recommends use of a 'no clean' solder paste for all its module products.
