Analysis Report for Vishay Thin Film
Date:
5/26/04
To:
Brett Shipley
From:
Peter J. Bush
Charge #:
Subject: Thermocycled lead free samples
Description of Sample:
Six samples of Sn96Ag3Cu0.5 surface mount resistors.
500 hrs 85c/85RH + 500 cycles -55-125c
Analysis Findings:
Three out of the six samples exhibited whisker growth. The whiskers were
short and typical in morphology for whiskers grown by thermocycling.
Maximum length observed 10 microns. The whiskers were all on the ends the
chips. Grain changes and recrystallization were observed, again typical of
thermocycled pure tin finishes.
Whiskers of this type have been observed to grow up to 50 microns after themocycling for 3000 cycles under similar conditions.
