Ces travaux s’inscrivent dans le cadre du projet GENOME (GEstioN OptiMisée de l’Energie). Ce projet s’intéresse aux solutions de packaging haute-température pour des modules de puissance 40 kW embarqués en aéronautique. Ils s’intègrent dans l’étude de fiabilité des modules de puissance, notamment, les solutions alternatives aux alliages de brasure. De par leurs propriétés physiques, l’argent et l’or-étain ont été sélectionnés comme techniques d’assemblage afin d’étudier et d’évaluer leur fiabilité. Pour ce faire, une méthodologie d’étude de fiabilité des modules de puissance a été définie dans le but de garantir l’exploitabilité des résultats. Ensuite, des analyses destructives et non-destructives ont été réalisées sur des véhicules de tests. Ceux-ci ont été vieillis en cyclages thermiques suivant différents profils afin de comparer leurs influences sur la fiabilité des VTs. L’étude du comportement thermomécanique des assemblages de puissance a été réalisée à l’aide de modélisations par éléments finis. Une méthodologie d’évaluation de la fiabilité des assemblages, basée sur l’étude de la contrainte thermomécanique accumulée dans les couches de joints métalliques, au cours de vieillissements accélérés, est développée. Un deuxième axe devrait permettre de comprendre les modes de défaillance, afin de mettre en lumière les limitations des vieillissements accélérés sévères. / This work is part of “GENOME” project which focuses on high-temperature packaging solutions for electronic power modules. Its mission is to study the reliability of power modules, in particular, the die attach layer. Due to the physical properties of silver and gold-tin, they were selected as die bonds to assess the evolution of their reliability during ageing. In order to achieve this, an appropriate methodology of the power modules reliability has been defined in order to guarantee the results exploitability. Destructive and non-destructive analyzes were carried out on samples aged by different profiles of thermal cycling. These analyzes allowed us to compare the influence of each cycling profile on the reliability of samples. A study of the thermomechanical behavior of power assemblies was carried out using finite element modeling (FEM). A methodology for evaluating the reliability of assemblies during accelerated ageing is developed. A second axis allows us a better understanding of the failure modes and their effects. It also highlights the limitations of severe accelerated ageing. Consequently, the choice of temperature profile is questioned and a limitation of the temperature profile severity must be considered, in order to avoid producing degradations that are not actually found in mission profile.

No. of bitstreams: 0 / Nas últimas décadas, têm aumentado substancialmente a quantidade de pesquisas focando no desenvolvimento e caracterização de materiais biodegradáveis, particularmente, filmes comestíveis. O uso de polímeros de fontes renováveis, preparados a partir de produtos vegetais, vem ganhando importância nessa abordagem. O concentrado de proteína de soja e amido de mandioca podem ser considerados uma alternativa aos polímeros petroquímicos. O processamento pela radiação ionizante pode ser empregado para a modificação de polímeros e macromoléculas, resultando em novos materiais com grandes perspectivas de utilização industrial. A indústria de alimentos, uma das indústrias tradicionalmente mais inovadoras, exige o desenvolvimento constante de novos produtos. A capacidade de proteínas e polissacarídeos de formar filmes, amplamente conhecida, é um ponto de partida para o desenvolvimento de novos materiais que atendam os variados requerimentos dessa pungente indústria. Neste trabalho elaboraram-se filmes a base de fécula de mandioca e proteína isolada de soja em duas proporções diferentes e posteriormente irradiados e analisados quanto às suas propriedades mecânicas, cor, absorção de água, permeabilidade ao vapor de agua, análise térmica TGA e DSC entre outros. Os filmes tornaram-se aparentemente mais solúveis e menos resistentes a perfuração com o aumento da dose de radiação aplicada. Com relação às propriedades térmicas observou-se que os filmes com maior proporção de proteína são mais resistentes. Os filmes apresentaram-se menos permeáveis na dose de 40 kGy, e, com relação a absorção de água, esta foi reduzida em função da dose de radiação. Filmes com boa resistência ao vapor de água e com reduzida absorção podem ser considerados adequados para embalagens de alimentos. A radiação mostrou ser uma ferramenta conveniente na modificação de materiais poliméricos principalmente para elaboração de filmes solúveis onde esta é uma nova tendência para embalagens bioativas. / Tese (Doutorado em Tecnologia Nuclear) / IPEN/T / Instituto de Pesquisas Energéticas e Nucleares - IPEN-CNEN/SP

Cette thèse s'inscrit dans le cadre du projet français FUI8-ORIGIN qui vise à développer les performances des réseaux domestiques en apportant des solutions sans multi-Gigabits faiblement radiatives, économes et pérennes. La solution ORIGIN est caractérisée par l'action complémentaire de deux technologies: les communications sans fil 60 GHz, avec notamment la création récente en Janvier 2013 de la nouvelle norme WiFi 60GHz, et la mise en place d'une infrastructure Radio-sur-Fibre (RoF) afin d'étendre la propagation de ses signaux radio fortement atténués par l'atmosphère et les murs, au sein de l'ensemble de la maison. Cette thèse porte sur le développement des composants et modules optoélectroniques bas couts, permettant d'assurer ces contraintes. Le travail implique de couvrir de la puce semi-conducteur au modules et jusqu'au système intégré dans le démonstrateur. Les puces sélectionnées sont caractérisées de manière précise en développant des bancs de mesures adaptées aux applications analogiques RoF. Les performances RoF ont été évaluées et comparées en termes de réponse en fréquence, de bruit et de non-linéarités. Un dimensionnement complet de l'infrastructure Radio-sur-Fibre pour le démonstrateur est ensuite mené, intégrant et dimensionnant le bilan de liaison global à partir modules et cartes réalisés et développés par les partenaires du projet. Le module transmetteur Radio-sur-Fibre (TRoF) est ainsi conçu, assemblé et testé. Les performances du module ont été mesurées et simulées à chaque étape de la procédure d'intégration. Le démonstrateur final basé sur l'architecture multipoint-à-multipoint a été réalisée à l'aide d'un nœud central optoélectronique pour la répartition du signal et d'une Green Box permettant le contrôle de l'allumage des différentes pièces, et ainsi la rationalisation du rayonnement et de la consommation du système. Une transmission bidirectionnelle en temps réel entre deux dispositifs de Wireless HD commerciaux à ~3 Gbit/s a été démontrée. Dans une dernière section de cette thèse, des directions pour améliorer les lasers à cavité émettant par la surface (VCSEL) et les phototransistors SiGe sont explorées. Des VCSEL analogiques avec une bande passante de plus de 25 GHz sont développés avec la société Philips ULM Photonics et mesurés. Notre action s'est concentrée sur les dimensions latérales de la structure, en bénéficiant des améliorations des couches verticale de la part de ULM Photonics. Outre les dimensions du VCSEL propre, ce travail a aussi visé l'amélioration des lignes d'accès pour permettre à la fois une meilleure dissipation thermique et une meilleure adaptation réactive du VCSEL à son électronique amont. Une nouvelle technologie de couplage optique collective et passive est enfin proposée. Originale et brevetée à l'occasion de ce travail, elle permet le couplage optique vertical à la fibre optique multimode et monomode de dispositifs optoélectroniques de petites tailles, inférieurs à 10µm, ainsi permettant simultanément de réduire les pertes de couplage, d'augmenter la fréquence de fonctionnement des composants couplés en réduisant leur dimensions, et de réduire le coût et le temps de réalisation du couplage / Wireless communication technologies have become one of the most popular and indispensable part of people's lives in the recent years, offering mobility and services never before available from mobile communication until local network communication. This work is based on the frame of the French ORIGIN project and intended to explore the Home Area Network using the most recent Wi-Fi standard at 60 GHz with the goal to present a solution for the upcoming days where MultiGbit/s wireless communication will be required. The ORIGIN solution is characterized by the complementary action of two technologies: 60 GHz Wireless communication and Radio-over-Fiber (RoF) infrastructure. The project pretends to propose a real prototype based on RoF transducers and a Multipoint-to-Multipoint architecture to cover the entire house. This thesis covers from the single optoelectronic chip devices until the system implementation and the final demonstrator. The light source and the photodetector choice were very important since it dictated the RoF transducer architecture. Our choice was on 850 nm multimode devices (GaAs VCSEL and SiGe HPT) which allow relaxed constraints on the optical packaging and, therefore, low cost solutions. In terms of performances those devices are limited in a few tens of Gigahertz of bandwidth which was the reason for the intermediate frequency (IF) architecture. This thesis work addressed the electrical and optical interconnection of the optoelectronic chip devices. It explored the integration of hybrid amplification stages and passive networks within optoelectronic receivers and emitters. The optical packaging issues were addressed through a conventional coupling technique using a ball lens first. The die device performances were evaluated and compared with a packaged module in terms of frequency response, noise and nonlinearities. Since performances are usually measured as link performances we proposed a definition of the Opto-microwave figures of merit, such as Opto-microwave gain, noise, nonlinearities and EVM. They are presented and integrated into behavioral models, allowing both the individual performances extraction and system design. The integration of the RoF module in the system is the final part of this thesis. The performances were measured and simulated at each integration step. The final demonstrator based on the multipoint-to-multipoint architecture was implemented using an optoelectronic central node for the signal repartition and the Green Box for signal controlling. Real-time bidirectional transmission between two commercial WirelessHD devices at ~3 Gbit/s was validated. In a final section directions to improve VCSEL and SiGe HPT are explored. 25 GHz analogue VCSELs are explored with a focus on their dimensions, improved access and the potential of a suited matching approach. A novel collective and passive optical coupling technology is also proposed for both VCSEL and top illuminated detectors that couple smaller and faster devices

Ce travail porte sur l'étude du mélange thermodurcissable - thermoplastique (époxyamine / polyetherimide avec séparation de phase) pour évaluer les performances électriques et thermiques. Ces matériaux seraient des nouveaux candidats pour remplacer la couche d'encapsulation dans les semi-conducteurs, par exemple ceux utilisés comme interrupteur dans les applications électroniques de puissance. Les mélanges de polymères seraient un nouveau candidat en tant qu'isolant pour le système. La matrice epoxy-amine seul et les melanges epoxy / Polyetherimide on été caractérisés par microscopie électronique à transmission, microscopie électronique à balayage, Calorimétrie différentielle à balayage, analyse thermogravimétrique, analyse mécanique dynamique, analyse diélectrique avec simulation analytique et des mesures de conductivité électrique et de tension de claquage ont également été entreprises. Ces techniques complémentaires ont d'abord été utilisées pour étudier la séparation de phases et ensuite pour quantifier la taille des nodules de thermoplastiques dans la matrice thermodurcissable. Cette séparation de phase a été examiné et a montré une diminution des valeurs diélectriques de 15% et une augmentation de la tension de claquage par rapport au système époxy-amine pur. / This work deals with the study of thermoset-thermoplastic blend (epoxy-amine/poly-etherimide phase separated) to assess the electrical and thermal performances. These materials would be new candidates to replace the encapsulation layer in semiconductors, for example ones used as switches in power electronic applications. Polymers blends would be a novel candidate as an insulator for the system. Pure epoxy system as well as Epoxy/Polyetherimide blends where characterized by transmission electron microscopy, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical analysis, dielectric analysis with analytical simulation, electrical conductivity and breakdown voltage measurements. These complementary techniques were used first to investigate the presence of the phase separation phenomenon and secondly to quantify the separated nodules size. The effect of this phase separation was examined and showed a decrease in the dielectric values of 15 % and an increase in the breakdown voltage compared to the pure epoxy system. It was finally simulated to show a close assumption of what is found experimentally.

Due to the rapid development of technology, electrical products are being shipped all over the world. The electronic components have gotten greater in capacity but are smaller in size, making them sensitive to electrostatic discharge (ESD). ESD packaging protects sensitive components from electrostatic discharge and electrical fields. There are different types of packaging solutions depending on the sensitivity of the product. Rigid packaging of insulating paperboard, impregnated with a thin, conductive carbon layer was used in this study. The conductive material is supposed to lead the static electricity away from the product, to the packaging which is insulated, where it safely can discharge. The inside of the packaging, normally dressed in a foam to protect the device inside, is supposed to be replaced with paperboard. The purpose of this master thesis is to investigate whether or not an ESD-packaging can be created by coating a paperboard with a dispersion containing nanographite and nanocellulose. Solid Bleached Board is a paperboard made by the mill Iggesund Paperboard, used for graphical products and packaging of high quality. Paperboard is made from cellulose, an environmentally sustainable raw material from the forest. Classifications of materials used in ESD packaging-solutions are divided into how quickly electricity moves through the material. Carbon is normally within the range of 10^2 to 10^6 Ω for sheet- and volume resistance. Maximal charge and maximal electrical discharge of the packaging are by standard not supposed to exceed 100 V and 50 nJ. Two different nanographite dispersions with different binders (polyvinyl alcohol and cellulose nanofibres) have been made. These have been coated onto the paperboard using a bench-coater. Measurements of ESD- and paperboard-properties have been performed onto the paperboard. The measured values were within the range of what was considered acceptable to be able to create an ESD packaging. The prototype was designed materially with solid bleached board, coated with a dispersion made of 220g nanographite, 22g cellulose nanofibres and 3791g water with a solid content of 8,2%. The design has been developed with the company's existing packaging in mind together with information about the already existing ESD packages. The results from the measurements show that it is fully possible to create and produce ESD-packaging, but needs further testing after this thesis. Societal, ethical and environmental aspects have been considered during the entire study. / På grund av den snabba tekniska utvecklingen transporteras elektriska produkter över hela världen. Elektroniska komponenter har fått större kapacitet men är mindre i storleken vilket gör dem känsliga för elektrostatisk urladdning (ESD). ESD-förpackningar skyddar känsliga komponenter från elektrostatisk urladdning och elektriska fält. Det finns olika typer av förpackningslösningar beroende på produktens känslighet. Styva förpackningar av isolerande kartong, impregnerade med ett tunt, elektriskt ledande kolskikt användes i denna studie. Det ledande materialet leder den statiska elektriciteten bort från produkten, till förpackningen som är isolerad, där den säkert kan urladdas. Förpackningens insida, som normalt är klädd med ett skum för att skydda produkten inuti, är tänkt att ersättas med kartong. Syftet med examensarbetet är att undersöka om en ESD-förpackning kan skapas genom att bestryka ett kartongark med en dispersion innehållande nanografit och nanocellulosa. Homogen helblekt kartong (Solid Bleached Board, SBB) är en kartong tillverkad av pappersbruket Iggesund Paperboard, som används för grafiska produkter och förpackningar av hög kvalitet. Kartong är tillverkad av cellulosa, ett miljövänligt och hållbart material från skogen. Klassificeringar av material som används i ESD-förpackningar är indelade i hur snabbt elektricitet rör sig genom materialet. Kol ligger normalt inom intervallet 10^2 till 10^6 Ω för yt- och volymresistans. Maximal uppladdning och maximal elektrisk urladdning av förpackningen ska inte överstiga 100 V och 50 nJ. Två olika dispersioner med olika bindemedel (polyvinylalkohol och cellulosa nanofibrer) har tillverkats. Dessa har bestrukits på kartongen med en bänkbestrykare. Mätningar av ESD- och kartong-egenskaper har utförts på kartongen. Mätdata låg inom det intervall som ansågs vara acceptabelt för att kunna skapa en ESD-kartong. Prototypen, sample B, är designad materiellt med homogen helblekt kartong, bestruken med en dispersion gjord av 220g nanografit, 22g cellulosa nanofibrer och 3791g vatten med en torrhalt på 8,2%. Designen har utvecklats med företagets befintliga förpackningar i åtanke tillsammans med information om de redan existerande ESD-förpackningarna. Resultaten från mätningarna visar att det är fullt möjligt att skapa och producera ESD-kartong, men det kräver ytterligare tester efter denna studie. Samhälleliga-, etiska- och miljöaspekter kommer att beaktas under hela studien.

<p>The production of insects for protein is projected to reach a market share of 1.33 billion USD, a rapid increase from the estimated 144 million USD share of 2019 market. The isolation of insect protein produces by-products, including chitin. Currently chitin is extracted from aquaculture by-products, such as shrimp and crab shells, and used to produce chitosan for various applications in the supplement and food industry. With the insect market expected to continue its growth, the feasibility of sourcing commercial chitin and chitosan from reared crickets’, and the application properties of its counterpart, chitosan, was investigated in this dissertation. In the first part of this dissertation, chitin from two commonly reared crickets in the Unites States, <i>Acheta domesticus</i> and <i>Gryllodes sigillatus</i>, was successfully extracted, purified, and identified as a commercially viable option for chitin and chitosan. Extensive crustacean chitin studies served as the foundation of purification steps, however durations were adjusted to account for intrinsic differences between insects and crustacean exoskeletons. Furthermore, cricket chitosan was prepared and optimized with varying degrees of deacetylation. As expected, cricket chitosan had lower molecular but did not have a detectable effect on the bioactive properties tested. All cricket chitosan produced had similar lipid binding capacity <i>in vitro</i>. Additionally, the microbial inhibition of cricket chitosan and commercial chitosan (~70% DDA) were not significantly different when evaluated against <i>L. innocua</i> and <i>E. coli</i>. High DDA cricket chitosan showed greatest bacterial inhibition as expected. In the second part of this dissertation, cricket derived chitosan showed similar and improved food packaging properties, when evaluated against commercial shrimp chitosan. microstructure analysis provided by scanning electron microscopy showed greater compaction and agglomeration of cricket chitosan films. The change in microstructure may be attributed to the increased complexity generally attributed to insect chitosan materials, a result of remaining melanin and protein in close association with insect exoskeleton chitosan. As a result, cricket films had similar or increased tensile strengths but decreased elongation percentages when compared to shrimp films. Water vapor permeability of cricket films was decreased due to tortuosity. Residual melanin likely played an important role in increasing cricket film surface hydrophobicity and providing enhanced light barrier properties. Overall, this dissertation successfully shows the potential of crickets as insect derived chitin and chitosan, and its effectiveness as a lipid binding and antibacterial agent, as well as its potential use in biobased food packaging. </p>

Rökning är en ovana som många personer ägnar sig åt, det speglas inte minst på gatorna vart man än går. Fimpar på gator runt om i städer är en miljöbov som sällan uppmärksammas. Trots att det finns allmänna askkoppar för fimparna att slängas i, hamnar de ofta på gatan och blir en fara för djur och natur. Denna studie syftar på att ta fram ett designförslag på hur en omkonstruerad cigarettförpackning, som rymmer cigarettfimpar, kan se ut. Det undersöks även hur en cigarettförpacknings konstruktion kan uppmana konsumenter att inte slänga fimpar på marken, vilket i stort kan ha en positiv effekt på miljön. Den målgrupp som är relevant att undersöka är alltså alla rökare i Sverige. En digital enkät skickades inledningsvis ut för att ta reda på folks vanor och åsikter kring rökning. Detta resulterade i en bekräftelse av forskningsfrågorna där respondenterna önskade en smidig lösning som minskade antalet fimpar på marken, varpå några föreslog att en cigarettförpackning hade en funktion liknande snusdosans dubbla lock. Representanter från kartongproducenter kontaktades för att få information om material och dess möjligheter. Designprocessen inleddes med en konceptgenerering med hjälp av mindmapping och brainstorming. Ur detta föddes tio idéer som sedan reducerades till tre koncept genom en pugh-chart. LoFi-prototyper skapades av dessa och presenterades för åtta deltagare under semistrukturerade intervjuer. Intervjuerna resulterade i att två koncept föredrogs, men författarna tog beslutet att utveckla ett av dem. En slutgiltig prototyp skapades, vilken var konstruerad som en vanlig cigarettförpackning med flip top lock, men var knappt två centimeter längre. Detta gav utrymme i förpackningens botten att ha en separat plats för använda fimpar. Värderingen av den slutgiltiga prototypen skedde genom ytterligare en digital enkät som skickades ut till samtliga deltagare från den tidigare semistrukturerade intervjun. Genom att de besvarade påståenden samt beskrev prototypen fritt kunde det konstateras att alla deltagare inte är lika positivt inställda till denna förpacknings utformning, men att majoriteten ändå skulle använda en cigarettförpackning som denna till att förvara fimpar när inget bättre alternativ finns. Dessutom uppgav respondenterna att förpackningen skulle motivera dem personligen att slänga färre fimpar på marken, samt att förpackningen skulle minska antalet fimpar i naturen generellt. Därmed kan det konstateras att en alternativ cigarettförpackning troligtvis skulle minska antalet fimpar på marken och ge en positiv effekt på miljön i stort. / Smoking is a bad habit whose traces can be seen widely on the streets. The cigarette butts pose an environmental threat that seldom is given attention. Although there are public ashtrays, cigarette butts often end up on the ground and become a risk for animals and nature. This study aims to produce a design suggestion for a reconstructed cigarette packaging that can hold used cigarette butts. It will also be examined how a cigarette packaging’s construction can invite consumers to avoid tossing cigarette butts on the ground, which at large can have a positive impact on the environment. The relevant target group that will be analysed is all smokers in Sweden. A survey was distributed in order to examine the smoking habits of persons and their opinions about smoking and cigarettes. The result showed that the respondents wanted a handy solution that would reduce the amount of cigarette butts on the ground, whereupon some proposed that the cigarette packaging could utilize a feature like the double lid on the packaging of swedish snus. Representatives from large carton board producers were also contacted in order to retrieve information concerning material and their possibilities. The design process started by generating concepts with mind mapping and brainstorming. This resulted in ten ideas that later was reduced to three concepts via a Pugh-chart. LoFi-prototypes of the three concepts were created, which were presented to eight participants in semi structured interviews. The interviews led to two concepts being prefered by the respondents, where the writers chose to develop one of them. A final prototype was developed and produced. This was constructed as a general cigarette packaging with a flip top lid, but was barely two centimeters longer. This created a space in the bottom of the packaging to contain used cigarette butts. The valuation of the finished prototype was done by an additional survey that was distributed to the same participants that partook in the semi-structured interview. By having them answer statements and describe the prototype freely, it was clear that every respondent didn’t have a positive attitude towards the prototype’s construction. However, a majority of the participants claimed that they would use a cigarette packaging like this to hold the cigarette butts when no better option was available. Additionally, the respondents stated that the cigarette packaging would personally motivate them to discard fewer cigarette butts on the ground, and also that the cigarette packaging would decrease the amount of cigarette butts in the environment generally. Consequently, an alternative cigarette packaging would possibly reduce the amount of cigarette butts on the streets and therefore positively affect the environment.

The project focuses on the packaging process of the smart card manufacturing industry. The idea of the project concerns how to increase production packaging efficiency by introducing a control system. After taking an in-depth look at the current production environment, the following system goals were defined: packaging time reduction, cost reduction, decrease in human errors, and reducing the number of customer complaints. To achieve these goals, the thesis project was divided into the following tasks: discovering a feasible solution, actual system development, testing, and evaluation. The proposed system is based on hardware (i.e. barcode scanner, and barcode printer) integrated with customized control software. The barcode scanner acts as a bridge between the system and the production process by scanning a barcode printed on each product. The system prints the required information label for the product’s package according to the scanned product. This label is pasted on the product’s box and is used as a tracking tool during further production steps. The system is very flexible and suits any packaging model. Other functional properties maintained in the system include data security, product traceability, and real time production monitoring. Testing of the system was done in an actual production environment at an Oberthur Technologies manufacturing site. Two production lines were selected to test the system’s functionality, specifically the SIM card production packaging line and the Scratch card/ Bank Card production packaging line. The results obtained during the evaluation phase of the proposed system show that the proposed solution decreased the packaging processing time by (27.3%) over the previous values. Moreover, the resulting human error rate is close to (zero%). / Projektet fokuserar på förpackningen processen smartkortet tillverkningsindustrin. Tanken med projektet handlar om hur att öka effektiviteten produktionen förpackningar genom att införa ett styrsystem. Efter att ha tagit en fördjupad titt på den nuvarande produktionsmiljö, var följande systemkrav mål definieras: nedsättning förpackning tid, minskade kostnader, minskad mänskliga fel och minska antalet kundklagomål. För att uppnå dessa mål var examensarbetet indelad i följande uppgifter: att upptäcka en genomförbar lösning, faktisk systemutveckling, testning och utvärdering. Det föreslagna systemet bygger på hårdvara (dvs streckkodsläsare och streckkod skrivare) integreras med skräddarsydd styrprogram. Den streckkodsläsare fungerar som en bro mellan systemet och produktionsprocessen genom att läsa en streckkod tryckt på varje produkt. Systemet skriver den erforderliga informationen etiketten för produktens förpackning enligt den scannade produkten. Denna etikett klistras in på produktens ask och används som ett verktyg för spårning under ytterligare produktionssteg. Systemet är mycket flexibelt och passar varje förpackning modell. Andra funktionella egenskaper bibehålls i systemet inkluderar datasäkerhet, spårbarhet och i realtid övervakning av produktionen. Testning av systemet gjordes i en verklig produktionsmiljö i ett Oberthur Technologies tillverkningsanläggning. Två produktionslinjer valdes för att testa systemets funktionalitet, särskilt i SIM-kortet produktionen förpackning linje och skrapkort / Bank kortproduktion förpackningslinje. De resultat som erhållits under utvärderingsfasen av det föreslagna systemet visar att den föreslagna lösningen minskade tiden förpackningen behandling av (27,3 %) jämfört med föregående värden. Dessutom är den resulterande mänskliga fel som ligger nära (noll %).

Purpose: The purpose of this thesis is to investigate how food start-ups (FS) can make their primary food packaging (PFP) more eco-friendly by identifying and evaluating the performance of suited packaging alternative. The purpose was fulfilled by answering the three research questions:  RQ1) How to assess the eco-friendliness of PFP? RQ2) Which are areas of improvement in environmental performance? RQ3) What are the differences in performance across similar PFP’s?  Methods: To answer the research questions both the literature review and empirical data was required. The literature study was conducted to gather relevant theories about primary food packaging in food start-ups. To get the required empirical data, a single case study was conducted at a case company that suited the subject. The case study consisted of multiple interviews and document study. This enabled for an analysis in the form of pattern matching in order to answer the research questions and achieve the purpose.  Findings: The Study found that to assess the PFP that have direct impact on the environment the functional features and the environmental framework play a central role in the eco- friendliness of PFPs which analyzed the requirements for the PFP and a multi criteria decision making approach for the environmental assessment for the Green-PE. The stakeholder expectations were found by analyzing the criterion for the PFP. In addition, a comparison for an eco-friendlier alternative was analyzed with the current Green-PE to justify the performance for the PFP in FS.  Implications: The study results present practical implications with assessing the current Green-PE and evaluating the gaps for improvement areas, while also comparing similar PFP which is an eco-friendlier option for food packaging start-ups. As there has been no general theoretical implications, the findings of the thesis can be used as a basis for deeper insights into the subject through more extensive research.  Delimitations &amp; Scope: The focus was to identify and evaluate the current PFP environmental impact and not the other aspects of the life cycle assessment since the scope was limited. Also, a single case study was used rather than multiple case studies to analyze the eco-friendliness for PEPs.
