What they SHOULD have done, yes ... but our ham-club presentation from
a professional re-work soldering instructor said that's rather more
observed in the breach these days, most boards leave the line "dirty".
The new EU RoHS rules probably change everything again -- the new
silver-solder will take somewhat higher heat, luckily the current
board designs don't have a lot of metal to heat -- and luckily the
cheaper, less-strong varieties of silver solder being developed for
the RoHS applicatoins are Eutectic or Near-Eutectic, so we won't have
the large number of cold joints we had with Sn60/Pb40 penny-pinching.
