It was found that at high frequencies the tangential electrical fields will be much greater than the values reported in the literature. Despite relatively strong longitudinal E-fields and radial currents, the comparison revealed that, provided the circuit parameters are properly evaluated, the errors introduced by a simple distributed circuit model under the quasi-TEM assumption are not excessively large. Therefore, the telegraphist's equations may give good results up to frequencies of 10 GHz or higher for transmission lines of small geometries commonly found in microelectronics packaging. A second case of three coupled microstrips of rectangular cross-section was also analyzed and compared with network measurements. It was found that the dispersion occurring in microelectronics packaging interconnects at frequencies up to the microwave band is anomalous.<<ETX>>","PeriodicalId":202574,"journal":{"name":"Proceedings 1992 IEEE Multi-Chip Module Conference MCMC-92","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131228219","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 equation for lossless lines is linear and very simple; the equation for lossy lines is quadratic. In terms of computational costs, the evaluation of delay involves 24 multiplications, and is several orders of magnitude faster than using circuit simulation or transmission line analysis programs to calculate delays. Using the macromodel, the authors derived the dependence of delay on several technology parameters, and calculated the sensitivity of delay to the circuit parameters.<<ETX>>","PeriodicalId":202574,"journal":{"name":"Proceedings 1992 IEEE Multi-Chip Module Conference MCMC-92","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130871814","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 author offers perspectives on the performance and economics of MCMs and VLSIs. In particular, he examines the dependencies and contrasts the competitiveness between these two integration technologies. The analysis points to opportunities and action agendas for MCMs. It is concluded that the MCM is an important system integration technology that, if properly utilized, can provide significant added value. It should not be approached as a VLSI replacement. Rather, it should be used as an important adjunct to VLSIs.<<ETX>>","PeriodicalId":202574,"journal":{"name":"Proceedings 1992 IEEE Multi-Chip Module Conference MCMC-92","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121896293","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 end product was to be a working MCM prototype that could be characterized and tested at speed. The project was divided into four phases: (1) vendor evaluation; (2) electrical design; (3) mechanical design; and (4) reevaluation. Each phase is described. This work led to the determination that MCMs are a viable technology when speed and real estate are design drivers. It was found that maintaining good communications with the vendor throughout the design cycle is important. The limitations on the design tools may require the use of multiple tools to verify the functionality and performance of an MCM.<<ETX>>","PeriodicalId":202574,"journal":{"name":"Proceedings 1992 IEEE Multi-Chip Module Conference MCMC-92","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129925518","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}
