· Ball shear strength of nonencapsulated silver wire decreases dramatically after PCT aging compared with copper wire or gold wire and some samples show zero shear strength after PCT 96 hours and PCT 192 hours for silver wires doped with Pd/Au. Furthermore, larger bonding power induces higher ball shear strength.

Soon gold was being degraded by the deliberate addition of platina, which was difficult to detect because of its similar density. Indeed the first written reference to platina noted that the mixing of platina and gold was banned ().This contamination required the colonial authorities to improve the existing methods of identifying platina and of separating it from the gold with which it occurred.
