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. 1 Vishay Thin Film Lead Free Wraparound Process Vishay Longest whisker observed. 2 Vishay Thin Film Lead Free Wraparound Process Vishay 3 Vishay Thin Film Lead Free Wraparound Process Vishay 4 Vishay Thin Film Lead Free Wraparound Process Vishay Qualification Report # 28249 Vishay Thin Film Lead free wraparound process Models series: P ns, PTN, L ns, M Eight lead-free wraparound termination lots consisting of 20,000 units with terminations of 96.5%Sn/3.0% Ag/0.5% Cu were subjected to the following Test: Table 1 Eight production lots tested Standard VTF In-House Process Qualification per MIL-PRF-55342 TEST REQ.
