I used a heat gun. You will need ventilation, those fumes can't be good for
you.
I covered the PCB with the paste and always did it in one pass. But I've
since read that it is better to do multiple passes with a thinner coat. I
have to agree with that, a thick coat can easily turn into a mess. I've
lost a lot of time with that.
It is much easier to add another coat, than to try to wipe off excess paste.
I used ordinary white paper towels, not that brown paper, the nice white
stuff. The excess paste wipes off nicely when the layer is not thick.
Right now I'm using liquid tin from MG Chemicals; just drop the PCB in a
plastic bin and let it soak in the liquid for a few minutes. I do it
outside and I don't know how many PCBs this liquid can process. I figure it
is depleting and eventually will do nothing.
