In the manufacturing process of the main board on tablets, in the area of welding technology, there was a problem in the micro USB connector soldering process causing high defect rates. The purpose of this article was to conduct assessment and proposal for improvement in this process. The methods and techniques used were quality tools PDCA cycle, cause and effect diagram and 5W2H. Among these solutions, the choice was to implement pallets of durestone to maintain the alignment of the connector on the reflow soldering oven. The results show a reduction in failure rates from 12.40% to 0.09% in the production line, which avoided the institution generate a total of 24,800 defective boards on the total to be produced. The total cost savings from logistics repair of these boards was approximately 70.002,80.

The objective of this work is to present the effects of the insertion of censored data in the reliability analysis of electric lamps using three non-parametric estimators, Kaplan-Meier, Nelson-Aalen and Life Table as comparative methods. The results showed that the difference between the survival function with the censored and uncensored data is more intense in the case of the presence of type I censorship. It was verified that the estimators tend to overestimate the survival with the censorship increase, independently of the Type of this, however, they maintain the same downward trend of survival over time. In the overestimation question, the estimator Nelson-Aalen showed ahead of the others.","PeriodicalId":236176,"journal":{"name":"Journal of Engineering and Technology for Industrial Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125269046","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}

The study was built from the comparative analysis method that seeks a causal inference, trying to define a comparative systematic illustration, that is, it seeks to verify the main attributes of a model and to compare it to another model by checking the advantages and disadvantages of one or the other. The choice of the theme was therefore motivated by the comparative analysis of the following points: the demand for more work in relation to the issue of slab production and execution; the ambiguity surrounding the discussions and proposals on the predominantly regional theme; and the need to evaluate the production and execution of the two (2) types of slabs (ribbed and steel deck type). the steel deck slabs have a lower cost than the ribbed slabs, corresponding to a 20.0% difference. However, for spans greater than 6.0 m, the relative cost of the steel deck slab increases significantly, reaching a difference of more than 70%.","PeriodicalId":236176,"journal":{"name":"Journal of Engineering and Technology for Industrial Applications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121881648","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}
