The air cavity between substrate and substrate is connected by solder balls and control of its stand of height is important to keep antenna performance. But the AiP would have higher solder ball crack risk under reliability test due to larger package size than AiP applied in mobile device. Thus, stress simulation was performed to check high stress location of solder balls under thermal cycle test (TCT) of package level reliability (PLR) and drop test of board level reliability (BLR), and a solution of adding glues was proposed to reduce solder ball crack risk. Warpage simulation was also performed to check warpage performance. Stress simulation showed solder ball stress could be reduced about 30% and 6% for TCT and drop test conditions, respectively. And both reliability results with adding glues showed passed. For package warpage portion, warpage value and contour were close and similar between simulation and moiré measured results. Thus, adding glue was a successful solution to reduce stress and pass reliability tests.","PeriodicalId":413776,"journal":{"name":"2022 International Conference on Electronics Packaging (ICEP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125692964","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}

Therefore, we propose the low temperature sapphire bonding using SPAB by introducing SiO<inf>2</inf> intermediate layers. For this, in this study, we investigate the applicability of SPAB to the deposited SiO<inf>2</inf> layer on sapphire wafers by reactive sputtering. The SiO<inf>2</inf> layer has a suitable surface smoothness and composition, which are comparable to the fused silica.
