Isn't it possible to get away with the sioldering without a soldering iron
at all? The manufacturing lines are using allegedly some kind of solder
flowing in circles that makes a bulge on the surface of the liquid and
the PCB is stuck into the bulge. At least someone has been describing it to
me this way.
Isn't it possible to heat up amount of solder in an old pot or pan, add a
handful of rosin and then carefully dip the board into it?
I have once seen in TV how some guy was casting tin soldiers this way at home.
I have been soldering a copper HDD water cooler this way - put an iron plate
over gas stove, heated the biggest part up, and then it was just play with
liquid solder and rosin (I bought a 1kg bag in a drugstore).
Someone has also described a homebuilt thru-plating station (however it
isn't still probably a finished design yet).
Just add a homemade 150 000 rpm compressor-driven spindle PCB drill with
linear X-Y drives and 2um precision and you can save walking to PCB
manufacturer (however the machine weighs 6 tons - I fear it would
probably fall through the room's floor ;-) )
