In some documents, people use the symbol - Pb - to indicate lead metal based 
solder.  Component "lead" is too well entrenched to change.  
 
So, dare we call lead metal solder parts Pb'd or Pb'ed finish? 
 
Also, wish we had called the RoHS compliant parts "Pb safe" or "Lead-Safe" and 
not Lead-Free, as they can contain 0.1%, or 1000 ppm, of Pb.  
 
The utlimate oxymoron is to take a Pb-Safe component and "re-tin" it with Pb 
based solder. 
 
What a mess!!!!!

It would nice if we could work out a way of distinguishing between 
"leaded" meaning having contacts via leads rather than pads and 
"leaded" meaning containing the element lead.
