Steven and all,

I found this to be an interesting development........

Abstract: Selective silver and solder plating is an important pre-plating
method for semiconductor leadframes. An ink jet printing system was
successfully used to resist mask the leadframe for selective plating. A BTA
aqueous solution was developed (as a new peeling solvent) to replace the
conventionally used organochloride solvent which is highly toxic.
