Hi Van,
Of course you can  apply solder paste on CN pad and run through Reflow.
But you should pay attention some matters:
- Which side of PCB are CNs on? Your CNs should through Reflow only one
time.
- Solder paste may pass the hole and stick on the surface of supporting
plate of Printer, so you can exchange the supporting plate by supporting
pin.
- solder paste amount should be enough to decrease re-touch by solder iron.
I will attach our stencil specification of stencil opening for CN pad.
Please refer.
Bye
