Hi Neighbor,
Dendrite and related Electrochemical Migration is supported by residual
contamination, moisture and bias. Have you tried an extraction cleanliness
method/test like IC or HPLC to determine cleanliness? (Not Ionic
Conductivity)

Best regards,

Subject: [TN] Dendritic growth tests


Hello All,
 I have received components from a certain vender in the past and over
a period of time the parts experience rapid dendritic growth. We have
tested the parts per the following specs, but I was wondering if there
were any other tests that could help us determine this issue sooner?

Specs: Telcordia GR-78
Component Type: QFP 44 pin
