This method of operating increases the priority for a particular product and expedites its flow through the factory. However, the impact of the schedule disruption on the remainder of the products' scheduled is unknown. A simulation of a medium sized electronics factory provides an opportunity to analyze the impact of this procedure on the jobs being processed. The effect of increasing the percentage of \"hot\" jobs on the remainder of the jobs being produced is examined. The results indicate that as the percentage of \"hot\" jobs increases, the time to process normal orders also increases. The establishment of an upper limit on \"hot\" orders will permit a factory to operate effectively and minimize disruptions.<<ETX>>","PeriodicalId":206206,"journal":{"name":"Proceedings of 15th IEEE/CHMT International Electronic Manufacturing Technology Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130575525","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}

Two two LIC (line interface controller) modules are designed with two large ASICs (plus memory) and prototyped using thick film gold conductors with 3 mil line/space and 6 mil via criteria. The second prototype of the LIC module utilizes silver conductors at 5 mil line and gap to further reduce cost. The second module design uses more bare die (field programmable gate arrays and memory) for a much higher interconnect density but still uses existing design guidelines. It is believed that 4 mil vias can be achieved in production and will be developed for future designs require higher density. Diffusion patterning allows a 50% reduction (4-6 mil) in via size versus traditional printed vias (10-20 mil).<<ETX>>","PeriodicalId":206206,"journal":{"name":"Proceedings of 15th IEEE/CHMT International Electronic Manufacturing Technology Symposium","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132873701","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}

Three quality metrics are defined and used as measurements of process improvement. The application procedure is divided into five stages, of which the implementation stages one and two have been performed. The data show that a system can be described by an equilibrium state, a transition period responsive to shifts in the input, but exhibiting substantial hysteresis. A transition period between different equilibrium states is clearly observable. The memory that the pad has due to previous recipe is also clearly demonstrated.<<ETX>>","PeriodicalId":206206,"journal":{"name":"Proceedings of 15th IEEE/CHMT International Electronic Manufacturing Technology Symposium","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125645449","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}
