Perhaps, but third-world recyclers are not known for gentle treatment
during the parts removal process. There have been lots of videos and
descriptions on the web that are truly eye-opening. The process
generally involves an intense heat source (everything from gas stove
burners to campfires) over which children hold PC boards, and when the
solder is good and flowing (maybe hundreds of degrees above its melting
point) they give the boards a mighty whack on the edge of a table so the
parts come flying off.
They are NOT using temperature-controlled vacuum desoldering stations.
I'm not particularly interested in a voltage reference IC that has been
overheated for a prolonged period, then subjected while hot to a 50G whack.
Best regards,
Charles
