This stage has a moving-coil-type linear motor using an NdFeB magnet, which is about 1.5 times as strong as SmCo/sub 5/ rare-earth magnets. Computer aided engineering, including finite-element analysis, was applied to realize optimum design. A two-mode control method, consisting of a traveling mode and a positioning mode, has been developed to obtain stability and high speed positioning. Travel is 50 mm*50 mm, and maximum acceleration is 50 m/s/sup 2/, which is five times as fast as conventional XY-stages.<<ETX>>","PeriodicalId":137899,"journal":{"name":"Fourth IEEE/CHMT European International Electronic Manufacturing Technology Symposium","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125799847","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 authors examine the reliability of plastic leaded chip carriers (PLCCs) in two commonly used sockets. Components are found to have different planarity problems than are commonly found in surface-mount assembly. The engineering factors considered in choosing the appropriate leadframe material must change when sockets are used. There are also serious vibration-induced problems which limit the number of manufacturing application areas in which sockets may be of reliable use. Restraining clips placed over the devices were examined to determine if simple modifications could be implemented to improve the vibration-induced problems. Dissimilar coatings between the package leads and the socket contacts are examined and discussed, as is the environmental stress range over which these sockets are of practical use in a manufacturing environment.<<ETX>>","PeriodicalId":137899,"journal":{"name":"Fourth IEEE/CHMT European International Electronic Manufacturing Technology Symposium","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123393039","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 substrate materials have been chosen and processed to given them thermal expansion coefficients which are similar to that of silicon, thus avoiding the creation of stresses in the device during thermal cycling. The thermal expansion matching of the glass-ceramic to the metal is achieved by the controlled crystallization of phases of known thermal expansion coefficients. This has been confirmed by X-ray and microstructural examination of a lithium aluminosilicate type glass-ceramic on copper/Invar/copper and of a magnesium aluminosilicate type glass-ceramic on molybdenum and on tungsten give values for the relative permittivity of the glass-ceramic layer of 5.9 and 5.8 respectively and values for tan delta between 10/sup -3/ and 10/sup -2/.<<ETX>>","PeriodicalId":137899,"journal":{"name":"Fourth IEEE/CHMT European International Electronic Manufacturing Technology Symposium","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121171960","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}

Because these areas are reaching their technical and cost limits in advanced systems, novel technologies are needed to advance further. One such technology is the multichip module, a hybrid for wafer-scale integration. In multichip modules, rather than forcing PCB and thick-film technology to higher densities, IC manufacturing processes are used to bridge the feature size gap. The opportunity to purchase wafers and select good dies could make this technology a less expensive assembly approach than surface-mounting technology (SMT). The ability to mix IC technologies and exercise more efficient thermal management makes this development a major stepping stone towards wafer-scale integration. Emphasis is placed on its impact on the PCB and thick-film hybrid industries.<<ETX>>","PeriodicalId":137899,"journal":{"name":"Fourth IEEE/CHMT European International Electronic Manufacturing Technology Symposium","volume":"1 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":"121809524","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}
