I beg to differ, especially if you use a little wire whose diameter was significantly smaller than the hole or even perhaps a porous metal insert, so as to allow the solder to penetrate the hole and make contact with all the layers. Through hole plating seems to have become an industry secret with only a few board house employees that know the process entirely...isn't this a forum for the do-it-yourselfer?
Don't get me wrong, chemistry is fun too......but if we can eliminate some steps to make it easier for the homebrewer, why not? Then more people can get involved with less intimidation to try something new.
To heck with molten solder, why not use conductive ink that has a high viscosity similar to a gell then just inject it into the holes with a syringe?
