Thanks Alexander, Charles, and Dave for recent responses to my inquiry about
the max. % Zn and Co in Sn-Pb solder joints and industry specs. related to
same.  With regard to your specific questions:

        Charles - I'm located at LeaRonal's world headquarters in Freeport, NY,
USA.

        Dave - Yes, in two separate instances, Zn and Co may have been present
unintentionally in the surface finish and thereby are suspected to have
contaminated the solder joint.


==> I have one more question for Technet - what about the maximum % P
allowable in a Sn-Pb solder joint?

        Thanks.
