copper inside the PCB usually does not contain lead... if you have  
screen on resistor or embedded resistor, it might contain lead (in  
glass  format).
copper  used in  PCB  are for electrical conductor  purpose,  
impurity, Pb included, will decrease conductivity... ideally, you  
want as pure as possibly, with minimum strengthening element, Pb is  
not consider as such.
IMHO.
