Solder bead can violate electrical clearance on electronics assemblies, while the detection under such component is only possible via X-Ray. Therefore, understanding and preventing such failures are a great concern in high-reliability industries (such as automotive and aerospace) to maintain a reliable and cost-effective manufacturing technology. This study analyses the solder paste position offset and cold and hot slump behaviour. The experiments are executed in a surface mounting factory environment, using automatic inspection methods, optical and X-Ray imaging for analysis. The results give an understanding of the failure mode of the solder beading, which can be used to ensure a preventive design and process parameters.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114976848","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}

Each of the five blocks adopts prior knowledge from the source fab in order to predict the yield in the target fab. The methods used for features selection are Pearson Correlation Coefficient, Distance Correlation, Maximal Information Coefficient (MIC) and Hilbert-Schmidt Independence Criterion Lasso (HSIC Lasso).

The intensity characteristics for two types of sources (1x36W and 2x36W) were investigated in relation with the distance from the source. Furthermore, the 2D space distribution of the intensity was analyzed by means of a customized mobile platform built on an iDrive Rock Climber vehicle. Other facilities of the proposed measurement experiment include live video transmission, automated data saving/analysis and remote control. Functionality tests performed in the laboratory confirm that the proposed system was properly designed and implemented. As future development, we will focus on correlating the effectiveness of a disinfection device, based on such UV-C lamps, in relation with exposure time, distance and target colonies type.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123366570","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}

Our challenge was to create a device light, cost effective, easy to use and with small power consumption that will work perfectly as an add-on to the cane indoor. Searching for a solution that is both versatile and cost effective, we came across an ultrasonic sensor, a light, easy to use, cost effective and low power consumption module that fitted our needs perfectly. The sensor can spot an obstacle at minimum 2 cm and maximum 4 meters [1] from the user, which makes is it the perfect candidate for our purpose. Creating a system composed of a programmable board, a jack module, a headset and a library that translates the distance to the user, we manage to make a fully functional prototype that can help any visual impaired user, with a little training, navigate indoor. The upgrade of the system will include more sensors and also an AI algorithm that will help even more the user and make the training even faster.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122971006","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}

Thereby, we introduce different N degree multilinear forms of the RLS algorithm, which come with a decrease in computational complexity and analyse their performance features.

The method how it works is really simple, some information has to be projected on the windscreen of the car, so the driver won’t have to look down on the gauges, and he can keep his eyes always on the road. A head-up display (HUD) is useful due to the fact that it can project the speed of the car on the windscreen and this way the driver can avoid speeding tickets. Also the projection on the windscreen it’s small and transparent, so it won’t bother the driver, which can watch the road, not the gauges. The projection method is straight forward, due to the fact that almost any object is reflected on a car’s windscreen, and a light up display, of a mobile phone, on low lighting conditions, it’s reflected even more. The goal of this work is to create a head-up display (HUD) using an Android mobile phone. This way this expensive feature for cars can be used in any car, by the use of a mobile phone only. The work presents the development process of an app, on a mobile phone, which can be used to project speed and optionally other informations on the windscreen of a car. The main concern of creating such an app is to figure out the mirroring of the mobile phone’s screen, to see an image which is not rotated, on the windscreen of a car.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129358517","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 power supply of the whole system was design to operate the system in the safety region and to bring the system in a homing position if the power supply is too low. The whole system is controlled over Bluetooth communication by a smartphone application. The degree of novelty is represented by the three available modes of operation, any of them can be used via smartphone application. The first mode of operation is a manual one, that can be very useful if the user wants to change the position of the biological probe tubes, the number of probe tubes, or to create a custom pattern of movement. The manual mode allows the user to move each motor to the desired position. This position can be saved to be able to run these positions, from the first to the last. Also, the saved positions can be deleted anytime. The second mode of operation is the semiautomatic mode. Using this mode of operation, the user has the possibility to choose which probe tube he wants to move and the position where the specific probe tube is placed. The third mode of operation is the automatic mode, which allows the user to move all biological probe tubes, one by one. The user has the possibility to stop this process anytime. The speed of movement can be changed within all modes of operation.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126082333","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}
