In the first case the convection from the top of component is blocked by the molding process. In the second case, free convection from top of component is considered. In both cases, the interconnection of components should be realized using printed conductive paste, as in the modified variant proposed in [1]. In this way, the heat generation in electronic components, in our case mid power LEDs, will be added with the supplemental dissipation caused by the current flow. For comparison purposes, there were investigated structures containing fixed linear resistors and/or structures printed on flat substrates.","PeriodicalId":6674,"journal":{"name":"2019 42nd International Spring Seminar on Electronics Technology (ISSE)","volume":"33 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91284862","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 polymer thick-film technology and the printed circuit technology are used as principles of the assembly and connection technology for the realization of conductive structures. Furthermore, the assembly of components on copper conductive bonding and the mechanical strength of the joints was tested.
