Increasing power and minimization of dimensions results in diametrical increase of thermal flux density. Current works are focused on high performance TIMs (Thermal Interface materials). The main role of such TIMs is efficient dissipation of heat from electronic device to the surface. Within the frame of the study thermal interconnections made of sintered nano silver pastes were evaluated in terms of the application as layers that effectively remove the heat from semiconductor structures. Structure of TIM interconnections between silicon die and ENIG (Electroless Nickel Immersion Gold) on copper/FR4 substrate was the object of the study. X-Ray CT analyses have shown that voids presence, contact surface and interconnection thickness strongly depends on nano-filled paste composition and technique of application. The results will be compared with results of further studies (i.e. electrical and thermo-mechanical measurements).","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123669185","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}

Gaze follows the movement of an item - “a target point” on the PC screen, the video camera captures the images of the eye and the PC determines the gaze position; this appears as “a map” on which the positions detected show as points around the target point. It is essential for the result to consist in a stable image or a map for gaze direction to be recognized by the PC. This paper presents a procedure for achieving stable cursor movement using low-pass filtering. It discusses the design, achievement and test results of a digital low-pass filter used in order to ensure the stableness of the point on the map that corresponds to gaze direction.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122717188","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}

Affects of processing parameters variation (firing profile) on properties of ferrite LTCC tape are determined for the commercially available ESL40011 tape. Obtained results provide information for complex permeability values for four different peak sintering temperatures (885°C, 1000°C, 1100°C and 1200°C) in the frequency range from 300 kHz to 1 GHz. Provided results show significant increase in permeability value with increase of the peak sintering temperature. This increase is followed with increase of losses in the ferrite material and the cut-back of the useful frequency range. In addition, these results can be correlated with results obtained by optical inspection of prepared samples.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116344287","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 both, the equipment and production processes have to be very flexible and well controlled. Nevertheless experience in PCB-production affirms that the outcome of some processes can be significantly influenced by the PCB-layout. Design of Experiments (DoE) is widely used for optimizing manufacturing processes and identifying influencing variables. Hence DoE should be useful for tagging crucial workpiece variables and evaluating their influence on particular manufacturing processes and machines. Using the example of copper deposition in mechanically-drilled areas of PCBs, a possible realization of DoE and its effectiveness is shown. The importance of focusing on the characteristics of the product to improve knowledge and quality of its manufacturing processes is also illustrated.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121584426","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}

Solder joints were fabricated on imm-Sn surface finish. The samples were aged in elevated temperatures and different humidity levels to induce the tin whisker formation. Three kinds of aging conditions have been used: 85°C/85RH%, 105°C/100RH% and 105°C/20RH%. The test duration was 3000 hours. Whisker growth was checked after every 500 hours by scanning electron microscope.

This paper shows a possibility of how to integrated two different types of filters in one multilayer module without mutual interference in HF area.

The sensor is a completely ceramic structure equipped with two gas inlets, hence measurements of differential pressure up to 20 kPa is possible. The properties of the sensor are determined in resonator mode, where frequency shift is observed during pressure and temperature changes. The sensor exhibits sensitivity of about -400 Hz/kPa and a thermal drift of about -2000 Hz/°C. Electronic circuits: amplifier and frequency counter are described. The thermal drift is compensated using an integrated thick-film PTC (positive temperature coefficient) resistor and software correction.","PeriodicalId":375711,"journal":{"name":"Proceedings of the 2014 37th International Spring Seminar on Electronics Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125744717","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}
