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
