but what exactly is the advantage over oven/reflow soldering?
I mean the whole industry does it this way, they must have reasons for it.
what i would use a cnc for is application of solder paste.
(and placement of parts ;-) )
i would have this plotter here, any idea how to make a solder paste
applying jig for it?
it surely can carry a thin hose and a nozzle....
any ideas welcome..
(and also ideas welcome where i can get CHEAP solder paste, is there any
way to make it
at home (like tin filings and flux or so)??
