Hello guys.
I'm making a PCB and I will use solder paste and a reflow oven to solder the components.
My question has to do with the fact that I will also have to solder some vias with a solder iron. Should I solder first with the iron or should I use the reflow oven in the first place? I don't know if the soldered wire will get out in the oven or not

 

If you mean soldering a piece of wire inside through hole, then it will most likely fall out.

 

Yes, that's it. I will solder it after then.
Thank you
