An investigation was made of the merits of suction vs pressure cooling, to find an effective cooling design for a certain module assembly. This showed that suction cooling has certain advantages because of the air flow escape from the circuitry section to adjacent spaces. Its air flow pattern provides maximum air accretion at the air exit, which is a critical area. That suction cooling will minimize air temperatures in that area is qualitatively developed and then quantitatively analyzed.","PeriodicalId":313371,"journal":{"name":"IEEE Transactions on Product Engineering and Production","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1965-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129619094","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}

Reduction in size and weight are obvious consequences of the technique. Reduced cost and improved reliability are still to be proven. Shrinking electronic assemblies and sub-assemblies bring about interconnection problems to the packaging engineer. Interconnecting devices are not only a factor in weight and size, but are a weak link in the reliability chain of the complete electronic system. These matters are considered in this report with especial attention to multilayer printed circuit boards.","PeriodicalId":313371,"journal":{"name":"IEEE Transactions on Product Engineering and Production","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123708857","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}

In conclusion, philosophical reflections are expressed concerning the marriage of both fields of engineering in this application, and the attendant obligations of management.","PeriodicalId":313371,"journal":{"name":"IEEE Transactions on Product Engineering and Production","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132382279","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}

Shielding calculations and their validity are demonstrated where applicable. The entire facility was provided with radiation safety features in the event of power failure. The electrical control circuit was designed for convenient and failsafe operation.","PeriodicalId":313371,"journal":{"name":"IEEE Transactions on Product Engineering and Production","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134629753","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}
