The relatively high failure rate of the (so-called) freaks is quickly demonstrated in such a test and can indicate a marginal or out of control process. This method of process control concentrates on the initial fallout as a means of determining the reliability of final products. Greater than 150°C stress temperatures should not be applied to plastic encapsulated devices. Since most epoxies have glass transition temperatures in the range of 150°C to 180°C permanent damage to the package could result.","PeriodicalId":369161,"journal":{"name":"13th International Reliability Physics Symposium","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122795675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through an analysis of the forward I-V data and specially performed tests, it was de-termined that the initial degradation was due to increases in the space charge recom-bination current while later degradation was due to decreases in the diffusion current. The initial changes in the space charge recombination current were caused by the diffusion of zinc atoms to the junction region via the Longini mechanism. Zinc diffusion also resulted in an initial increase in Po both under stress and room temperature storage conditions. The mechan-ism responsible for the decrease in the diffusion current was not identified, but most probably involved the silicon dopant atoms.","PeriodicalId":369161,"journal":{"name":"13th International Reliability Physics Symposium","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121417430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Below 175°C the fastest growing intermetallic compound was Ag3Sn. The Ni-Sn compoknd, Ni3Sn, was the slowest growing phase below 150°C, but the fastest growing phase above 175°C. The two Cu-Sn intermetallic phases, Cu3Sn and Cu6Sn5, had a combined growth rate which increases more slowly with temperature than the single intermetallic phases observed in the Ni-Snand Ag-Sn systems. The growth rate data plotted against reciprocal temperature satisfies the Arrhenius relationship and yields a range of apparent activation energies between 14.8 Kcal/mole for Ag3Sn and 37.6 Kcal/mole for Ni3Sn4. The growth of intermetallic compounds can affect the reliability of electronic parts through a reduction in lead solderability or a decrease in the mechanical strength of soldered connections. Lap shear testing of metal strips bonded with Sn demonstrated that strengths of both bonded Ni and Cu strips decrease as the thickness of the intermetallic compounds increase during annealing at 213°C. In the case of Ni-Sn, a 50% reduction in joint strength occurred after only one day-at temperature. For Cu-Sn, the reduction in joint strength occurred at a slower rate, and only a slight decrease was observed in the Ag-Sn lap shear samples. The degradation observed in the Ni-Sn and Cu-Sn systems is related to the growth rate of brittle intermetallics forming at the interface (i.e. Ni3Sn4 and Cu3Sn).","PeriodicalId":369161,"journal":{"name":"13th International Reliability Physics Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130015929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
