Abstract:
Conhecer as relações entre dados antropométricos e o estado nutricional das pessoas ajuda no entendimento das tendências em uma população. Este trabalho teve o objetivo de determinar em 62 jovens com idade entre 6 a 15 anos o IMC, o IAC e a relação entre IAC/IMC e utilizar método para agrupamento dos indivíduos. Os dados foram analisados por estatística descritiva e o método de agrupamento Joining. O IMC, o IAC e a Relação IAC/IMC, apresentaram os valores médios de 18,88; 27,62 e 1,51, respectivamente. Os grupos 1 e 2 apresentaram médias maiores que a média geral dos dados para o IMC. Os grupos 2, 3 e 4 apresentaram maiores valores médios que a média geral dos dados para o IAC. Os grupos 3 e 4 com média maior que a media geral para a relação IAC/IMC. Maiores relações de IAC/IMC ocorrem para indivíduos que apresentam menores valores de IMC e os maiores de IAC. O IMC aumenta com a idade e o IAC diminui à medida que a idade aumenta.

Abstract:
Objetivo: Comprobar si el índice de masa corporal (IMC), el índice cintura-cadera (ICC), circunferencia de cintura (CCi), circunferencia de cadera (CCa) y porcentaje de grasa corporal se correlacionan entre sí en personas mayores de 60 años. Método: Se realizó un estudio descriptivo correlacional en 1055 personas mayores de 60 años de diferentes países europeos pertenecientes al proyecto europeo IN COMMON SPORTS. Se realizó una valoración inicial de las variables antropométricas. Resultados: Correlación significativa del IMC con el porcentaje de grasa corporal, CCi y CCa pero no con el ICC. El ICC presenta correlaciones proporcionales significativas con el CCi, e inversamente proporcionales con el CCa. El género masculino muestra una correlación significativa entre el ICC y IMC, pero no con el porcentaje de grasa corporal. El IMC promedio muestra una tendencia general alta para ambos géneros. Mujeres mayor porcentaje de grasa. Conclusión: El IMC se correlaciona con ICC, CCa y CCi pero dependiendo del género. Los hombres mostraron correlaciones significativas entre IMC e ICC, pero en las mujeres no se encuentran correlaciones de estas medidas.

Abstract:
This paper proposes a novel Internal Model Control (IMC) method for the control of superheater steam temperature. The IMC is known for good robustness including handling of systems with time delays. While Iterative Learning Control (ILC) is a strategy for dealing with periodic disturbances. By using a combination of IMC and ILC, their individual advantages are used to increase the robustness against modeling uncertainties and handling time as well as decreasing the influence of the periodic disturbances affecting the superheater steam. Some simulation examples are shown to illustrate performance improvements that can be achieved by the new method over the conventional IMC and PID methods. Key Words: Superheater Steam Temperature; Internal Model Control; Iterative Learning Control

RESUMO Objetivo Adaptar a escala de silhuetas originais em cartões de papel e validar para uso digital. Métodos Participaram dessa pesquisa 88 jovens, os quais foram avaliados quanto ao índice de massa corporal (IMC) e questões sobre a imagem corporal com as escalas de silhuetas de papel e digital em relação ao corpo atual (IMC-A) e o corpo desejado (IMC-D). O processo de validação da escala digital se dá pela comparação entre o IMC com o IMC-A. Resultados Os resultados foram satisfatórios (0,70) para o grupo quando avaliado em conjunto e para o sexo masculino. No entanto, para o sexo feminino obtivemos um valor relativamente baixo, na concordância de Lin (0,64), mas com valores de ICC (0,89) e correlação de Spearman (0,85) aceitáveis. Conclusão As imagens no computador podem ser utilizadas para a avaliação da imagem corporal de jovens. Porém, é mais seguro realizar associações com questões referentes à prática de atividade física e do comportamento alimentar que, em conjunto, possam auxiliar na avaliação da insatisfação corporal.

Abstract:
BackgroundInflammatory mammary cancer (IMC), the counterpart of human inflammatory breast cancer (IBC), is the deadliest form of canine mammary tumors. IMC patients lack specific therapy and have poor outcomes. This proof-of-principle preclinical study evaluated the efficacy, safety, and effect on survival of neoadjuvant intratumoral (in situ) empty cowpea mosaic virus (eCPMV) immunotherapy in companion dogs diagnosed with IMC.MethodsTen IMC-bearing dogs were enrolled in the study. Five dogs received medical therapy, and five received weekly neoadjuvant in situ eCPMV immunotherapy (0.2–0.4 mg per injection) and medical therapy after the second eCPMV injection. Efficacy was evaluated by reduction of tumor growth; safety by hematological and biochemistry changes in blood and plasma; and patient outcome by survival analysis. eCPMV-induced immune changes in blood cells were analyzed by flow cytometry; changes in the tumor microenvironment were evaluated by CD3 (T lymphocytes), CD20 (B lymphocytes), FoxP3 (Treg lymphocytes), myeloperoxidase (MPO; neutrophils), Ki-67 (proliferation index, PI; tumor cell proliferation), and Cleaved Caspase-3 (CC-3; apoptosis) immunohistochemistry.ResultsTwo neoadjuvant in situ eCPMV injections resulted in tumor shrinkage in all patients by day 14 without systemic adverse events. Although surgery for IMC is generally not an option, reduction in tumor size allowed surgery in two IMC patients. In peripheral blood, in situ eCPMV immunotherapy was associated with a significant decrease of Treg+/CD8+ ratio and changes in CD8+Granzyme B+ T cells, which behave as a lagging predictive biomarker. In the TME, higher neutrophilic infiltration and MPO expression, lower tumor Ki-67 PI, increase in CD3+ lymphocytes, decrease in FoxP3+/CD3+ ratio (p<0.04 for all comparisons), and no changes in CC-3+ immunostainings were observed in post-treatment tumor tissues when compared with pretreatment tumor samples. eCPMV-treated IMC patients had a statistically significant (p=0.033) improved overall survival than patients treated with medical therapy.ConclusionsNeoadjuvant in situ eCPMV immunotherapy demonstrated anti-tumor efficacy and improved survival in IMC patients without systemic adverse effects. eCPMV-induced changes in immune cells point to neutrophils as a driver of immune response. Neoadjuvant in situ eCPMV immunotherapy could be a groundbreaking immunotherapy for canine IMC and a potential future immunotherapy for human IBC patients.

Abstract:
The discovery of computers and specifically the internet, led to fundamental changes in concept, strategy, tactic, and implementation of business, marketing, and marketing communications, which shifted from conventional to modern markets in the digital age. Integrated Marketing Communications (IMC) is a concept derived from the research made by practitioners and academics in anticipating the expiry of old strategies that are no longer reliable. In turn, IMC became a new paradigm to be used as a basic reference in facing challenges in the global market. The application of IMC concepts and strategies to the global market is known as Integrated Global Marketing Communications (IGMC) planning. Changes that occur in consumer behavior, message development patterns, the proliferation of media, especially digital media, and the integration of marketing communication elements are the basis of the IGMC strategic development plan. The implementation of the IGMC program can be expected to be a road map to achieve organizational and corporate success in the digital age. This paper synthesized the viewpoints of different experts and provides the author’s analysis, interpretation, and theorizing. Keywords: integrated global marketing communications, global consumer, global message development, global media penetration, and IGMC planning patterns.

Abstract:
Canine inflammatory mammary cancer (IMC) shares clinical and histopathological characteristics with human inflammatory breast cancer (IBC) and has been proposed as a good model for studying the human disease. The aim of this study was to evaluate the capacity of female and male mice to reproduce IMC and IBC tumors and identify the hormonal tumor environment. To perform the study sixty 6–8-week-old male and female mice were inoculated subcutaneously with a suspension of 106IPC-366 and SUM149 cells. Tumors and serum were collected and used for hormonal analysis. Results revealed that IPC-366 reproduced tumors in 90% of males inoculated after 2 weeks compared with 100% of females that reproduced tumor at the same time. SUM149 reproduced tumors in 40% of males instead of 80% of females that reproduced tumors after 4 weeks. Both cell lines produce distant metastasis in lungs being higher than the metastatic rates in females. EIA analysis revealed that male tumors had higher T and SO4E1 concentrations compared to female tumors. Serum steroid levels were lower than those found in tumors. In conclusion, IBC and IMC male mouse model is useful as a tool for IBC research and those circulating estrogens and intratumoral hormonal levels are crucial in the development and progression of tumors.

Abstract:
A travers une population d'enfants infirmes moteurs cérébraux (IMC), les facteurs permettant l'émergence et le développement du subitizing sont étudiés. L'étude 1 évalue la capacité de subitizing des enfants IMC et teste le lien entre cette capacité et les capacités motrices qui participent à l'apprentissage du dénombrement. L'étude 2 compare les capacités de subitizing, de reconnaissance de configurations et visuo-spatiales. Enfin, l'étude 3 teste l'effet de l'inversion de contraste sur la capacité de subitizing. La majorité des enfants IMC ont une limite de subitizing inférieure aux enfants tout-venant, quel que soit le contraste. Mais, cette limite augmente avec l'âge dans les deux groupes. Le développement du subitizing semble retardé chez les enfants IMC par des troubles visuo-spatiaux. Nos résultats appuient les modèles postulant que le subitizing repose sur la reconnaissance de configurations et suggèrent que les routines visuo-spatiales sont nécessaires à leur mémorisation
The factors likely to influence the emergence and the development of subitizing were analyzed, by testing a group of cerebral palsied (CP) children. The first study evaluates the CP children's subitizing limit, and its link with motor ability implied in the counting process. The second study compares subitizing, pattern recognition, and visuo-spatial abilities. Finally, a third study examines the effect of reversing the figure/background on subitizing limit. Most CP children have a lower subitizing limit than control children of the same age. However, subitizing limit improves with age in both groups, whatever the reversing of figure/background. CP children's subitizing limit appears to be delayed by visuo-spatial deficiency. It is likely that this deficiency does not allow a normal recognizing and memorizing of visual patterns. These results are congruent with the pattern recognition models of subitizing, and suggest that visuo-spatial routines are necessary to memorize these patterns

Abstract:
La parasitosis intestinal es de importancia para la salud pública por su alta prevalencia, su distribución prácticamente mundial y sus efectos. La prevalencia mundial es de 270 millones de niños en edad prescolar y más de 600 millones en edad escolar que viven en zonas con intensa transmisión de parasitos. En México, la frecuencia de la enfermedad se encuentra entre las primeras 20 patologías en preescolares y escolares. Estas afecciones por parásitos intestinales afectan el desarrollo físico y mental de los niños, aunado a las condiciones precarias de vivienda e higiene, se estima que el 18.9% de la población escolar se encuentra infectada por parásitos, muchos no son diagnosticados, reportados, ni estudiados, variando la estadística de forma considerable en diferentes zonas del país. Por otro lado, las estadísticas nacionales de nutrición muestran, en el 2017 entre la edad de 5 a 9 años, una tasa por cada 100,000 habitantes de: 115.27 para desnutrición leve, 15.18 para moderada y 4.67 grave, 198.94 en obesidad, (no distingue grados). Por la edad, la secretaria de salud utiliza Índice masa corporal como principal método de evaluación y diagnóstico, motivo por el cual se utilizará en este trabajo. Esto no proporciona una evaluación completa, pero si rápida para iniciar con un diagnóstico y tratamiento oportuno. (6; 28) Los estudios publicados que mencionan la relación entre parasitosis y desnutrición suelen ser significativa a nivel micronutriente, pero antropométricamente no se ha fijado una postura ya que la variabilidad de los factores de la población estudiada es mucha, aun así, los realizados en zona rural, en su mayoría, encuentran una relación. (7) A su vez, los niños escolares pasan la mayor parte de su tiempo en labores escolares y, en México, las estadísticas mundiales de rendimiento académico son muy bajas, los factores que contribuyen a esto son múltiples, pero nos enfocaremos al estado de nutrición y el padecimiento de parásitos intestinales para comprobar si, por su prevalencia alta, puedan ser significativos. Solo existe un estudio donde no se encontró relación, en México, los estudios no relacionan las 3 variables, pero si existe la relación de desnutrición y bajo rendimiento escolar. (29; 30) Este estudio se efectuó para dar a conocer como la incidencia de parasitosis en niños escolares está relacionada con la desnutrición que, a su vez, puede disminuir el rendimiento académico, afectando al niño respecto a su edad. Esto pretende ser útil al sistema de salud, fortalecer la prevención, mejorar las medidas higienico-dieteticas y mejorar la capacidad de aprendizaje en escolares, lo que aumentaría el nivel académico.

Objetivo: Comparar o estado antropométrico dos idosos negros a partir do IMC obtido pela altura estimada e a altura convencional. Metodologia: Trata-se de um estudo transversal realizado em amostra populacional de negros dos distritos sanitários (DS) Barra- Rio vermelho e Liberdade, na cidade de Salvador-Ba, sendo a população final do estudo constituída por 383 indivíduos com idade ≥ 60 anos. As variáveis do estudo foram: medidas antropométricas ― peso, altura e altura do joelho, índice de massa corpórea, cor autorreferida, escolaridade, nível socioeconômico. Utilizou-se o teste t-student pareado para analisar as diferenças de médias das medidas antropométricas e o teste de qui-quadrado para analisar as diferenças de proporções dos estratos do diagnóstico nutricional à partir do IMC convencional e do IMC estimado. Para a classificação da concordância de IMC´s foram calculados os valores de Kappa. Resultados: Dos idosos estudados 60,8% estavam na faixa etária 60-69 anos, predominando o sexo feminino (69,2%). A análise de concordância do IMCE apresenta para magreza em homens e mulheres 72,0% e 83,4%, respectivamente. Os valores observados de Kappa elevados para magreza e sobrepeso em ambos os sexos indicam que o IMC cuja altura foi estimada pelo Knee-height tem boa concordância com aquele obtido a partir de medidas convencionais de peso e altura. Tanto para a altura convencional, quanto para a altura estimada houve uma redução da altura média com o aumento da idade. Conclusão: Diante dos resultados encontrados, sugere-se, então, que na prática nutricional da assistência ao idoso, seja considerada a medida do joelho na estimativa da altura para efeito de cálculo do IMC e considerando que esta técnica é de baixo custo e de fácil aplicação pode ser utilizada em ambiente ambulatorial, domiciliar ou hospitalar.
Objective: To compare the anthropometric status of elderly blacks from BMI obtained by the estimated height and conventional height. Methodology: This was a cross-sectional study in a population sample of black health districts (DS) Barra-Rio Vermelho and Liberdade in the city of Salvador-BA, and the final study population consisted of 383 individuals aged ≥ 60 years. The study variables were: anthropometric measurements - weight, height and knee height, body mass index, self-reported color, education, socioeconomic level. We used the paired Student t test to analyze differences in mean values of anthropometric measures and chi-square test to analyze differences in proportions of the strata of nutritional diagnosis from the conventional BMI and BMI estimated. For classification concordance of BMI's were calculated Kappa values. Results: Of the elderly studied 60.8% were aged 60-69 years, predominantly female (69.2%). Concordance analysis of IMCE presents for men and women were 72.0% and 83.4%, respectively. It was observed that the high Kappa values for thinness and overweight in both sexes indicate that BMI whose height was estimated by Knee-height is in good agreement with that obtained from conventional measurements of height and weight. Both for the conventional height, the estimated height to the height was reduced with increasing average age. Conclusion: Considering the results, it is suggested, then, that in practice the nutritional care of the elderly, is considered as the estimation of knee height to calculate BMI and considering that this technique is inexpensive and easy application can be used in an outpatient setting, home or hospital.

The index of corporal mass (ICM) is broadlly used to measure the corporal mass of adults. A high fat index is related to heart and circulation problems, infertility, diabetes, arthritis, difficulty to move around or breathe and problems with cicatrization. Even though there are several studies about these problems, there is no specific method to evaluate weight excess in dogs objectively and precisely. The purpose of this research was to determine an index of corporal mass for dogs based on the existing IMC for human beings. Two hundred and forty six animals of no specific breed and different body conditions were analysed. They were not only measured and weighed, but also evaluated by two distinct veterinarians based on real subjective patterns, which can determine the corporal score. These procedures enabled the acknowledgement of the attained index. The conclusion was that IMCC between 11,8 and 15 kg/m² represent the ideal pattern for dogs of average size that weigh between 10 and 25 kilos.
O índice de massa corporal (IMC) é largamente utilizado por médicos para quantificar a massa corporal de pessoas adultas. Índice elevado de gordura está relacionado com problemas cardiovasculares, infertilidade, diabetes, artrite, dificuldade em se locomover ou respirar e prejuízos na cicatrização de feridas. Apesar de todo o estudo que se tem a respeito desses problemas, não há um método preciso e objetivo para se quantificar o excesso de peso em cães. A proposta deste trabalho foi determinar um índice de massa corporal canino (IMCC), a partir do IMC existente para humanos. Foram medidos e pesados 246 animais, sem raça definida e com diferentes condições corporais. Para dar validade ao índice de massa corporal obtido, os animais também foram avaliados por dois veterinários segundo os padrões subjetivos, já existentes. Verificou-se que valores do IMCC entre 11,8 e 15 kg/m² refletem o peso ideal para cães de porte médio, cujo tipo físico possui média de peso entre 10 e 25 kg.

Abstract:
Thesis advisor: Marc-Jan Gubbels
The apicomplexan parasite Toxoplasma gondii divides rapidly and asexually through a unique process of internal daughter budding. The physical infrastructure for this process is the cytoskeleton, which is composed of subpellicular microtubules, flattened vesicles (alveoli), and a meshwork of intermediate filament-like proteins. This meshwork is composed of a family of 14 inner membrane complex (IMC) proteins that were identified based on the presence of a repeat sequence shared across the Alveolata, the alveolin-repeat. All 14 proteins were cloned as YFP fusions to study their subcellular localization and antibodies were generated against several representative IMC proteins. Each IMC displays unique spatio-temporal dynamics throughout development, but four physically distinct localizations were identified: eight IMCs localize to the alveoli, four IMCs localize to a structure known as the basal complex, IMC11 localizes to the apical cap in mature parasites, and IMC15 localizes primarily to the centrosomes and early buds. IMC15 is of particular interest because its appearance before membrane occupation and recognition nexus 1 (MORN1) in the early bud suggests that it is the first cytoskeletal component to associate with the buds. A conditional knockdown of this protein using the destabilization domain (DD) reveals IMC15 has a strong affinity for the centrosomes that overcomes targeting of the DD fusion protein to the proteasome and the presence of IMC15 in the early bud may not be necessary for the division process. Conditional knockdowns using a tetracycline repressible promoter reveal that a minimal amount of IMC15 is sufficient for parasite survival. In order to further characterize IMC15, dominant negative constructs based on mutating putative palmitoylation sites or overexpression of deletion constructs are being pursued. Collectively, the IMC family is being incorporated into the temporal and spatial dynamics of cytoskeletal development through the creation of a comprehensive timeline of daughter bud assembly. These findings are contributing unprecedented detail to the cell division process

Abstract:
Introdução: A disfunção tiroideia influencia a massa corporal1, estando o hipertiroidismo associado a perda de peso e o hipotiroidismo a ganho. No entanto, no que diz respeito à associação de variações de peso a diferentes graus de função tiroideia dentro do considerado normal, pouco se sabe e a controvérsia é grande. Será que pequenas flutuações da função tiroideia, dentro do normal, poderão contribuir para alterações do peso? Objectivos: a) Averiguar a relação entre o IMC e os níveis da TSH, dentro do normal, como variáveis contínuas e por categorias. b) Comparar os IMC de diferentes tercis de TSH da amostra e as TSH entre obesos e não obesos. c) Por fim, estudar a relação entre a massa gorda e a TSH. Materiais e Métodos: Foram estudados dos cento e setenta e quatro indivíduos eutiroideus (cento e vinte mulheres e cinquenta e quatro homens), com idade média de 49,5±14,8 anos e IMC médio de 33,93±6,13 kg/m2 que tinham frequentado a Consulta de Nutrição e Actividade Física do Hospital Pêro da Covilhã, entre 2 de Janeiro de 2006 e 16 de Julho de 2009. Dados da função tiroideia normal, IMC e %MG foram recolhidos dos registos clínicos do hospital. Qualquer parâmetro da função tiroideia alterado era critério de exclusão. Procedeu-se à investigação de possíveis associações entre IMC, TSH e massa gorda. Resultados: Neste estudo, não se verificou correlação entre o IMC e a TSH, nem entre a massa gorda e a TSH, dentro do normal. Nenhuma diferença, estatisticamente significativa, entre os IMC foi encontrada quando se dividiu a TSH por tercis. O mesmo sucedeu quando se comparou a TSH de obesos e não obesos eutiroideus. Discussão e conclusão: Pelos dados da amostra, pode afirmar-se que, nem IMC e TSH, nem TSH e massa gorda estão associados, em indivíduos eutiroideus. Embora a disfunção tiroideia esteja relacionada com alterações do peso, conclui-se, por este estudo, que pequenas variações, dentro do normal, não estão relacionadas com alterações de peso e consequentemente do IMC.
Introduction: Thyroid dysfunction influences body weight, being hypothyroidism associated to weight loss and hyperthyroidism to weight gain. However, in relation to association of variations in weight to different levels of thyroid function, in normal range, little is known and there is great controversy. Will little variations of thyroid function, within the normal range, contribute to changes in weight? Objectives: a) Investigate the relation between BMI and TSH, in normal range, as continuous and categorical variables b) Compare BMI of different TSH tertiles and compare TSH between obese and non obese subjects. c) At the end, study the relation between FAT and TSH. Materials and Methods: One hundred and seventy four euthyroid subjects were studied (one hundred and twenty women and fifty four men), with mean age equals to 49,5±14,8 years and mean BMI equals to 33,93±6,13 Kg/m2 , that have acceded Physical Activity and Nutrition Consultation of Pêro da Covilhã Hospital, between the second of January in 2006 and the sixteenth of July in 2009. Normal thyroid function BMI and FAT data were collected from clinical registers of the hospital. Any altered thyroid parameter was exclusion criteria. We proceed to investigation of possible associations between BMI, TSH and Fat body mass. Results: In this study, we don’t verify correlation between BMI and TSH, neither between fat mass and TSH, in normal range. No difference, statistically significant, was found between BMI when TSH was divided into tertiles. The same happened when we compared TSH of obese and non-obese people. Discussion and conclusion: From data’s sample, we can say that neither BMI and TSH, nor TSH and fat mass are associated, in euthyroid subjects. However thyroid dysfunction is related to changes in body weight, we conclude, from this study, that little variations, in normal range, aren’t correlated with changes in body weight and consequently neither with BMI.

Abstract:
Interfacial intermetallic compounds (IMCs) in solder joints are formed during soldering and continue to grow after assembly. Excessive interfacial IMC growth may impact the reliability of solder interconnections due to changes in material behavior. The impact of thermal aging on IMC growth can be determined by subjecting assemblies to elevated temperatures and determining the interfacial IMC growth. This paper discusses the interfacial IMCs formed in the solder-Cu interface for SAC305, SAC105, and Sn-0.7Cu-0.05Ni+Ge (SN100C) assemblies. Test assemblies were produced using tin-finished 2512 resistors soldered onto OSP-finished copper lands. The assemblies were subjected to aging conditions of 100°C for 24 h and 600 h; and 150°C for 24 h and the impact of high temperature aging on the thickness of IMCs formed at solder-Cu interface was studied. Samples stored at room temperature for 600 h were the reference specimen for the experiment. The IMC growth observed in the lead-free solders was compared with that in eutectic SnPb. Interfacial IMCs formed in room temperature conditioned specimens were scallop shaped and non-uniform. The IMC structure evolved with aging temperature and duration resulting in smoother and more uniform IMCs in 100°C/600 h aged samples. A comparison of IMC thickness in the solders at given aging conditions revealed that SAC305 exhibited highest IMC thickness, followed by SAC105 and SN100C. SnPb showed the least IMC thickness at all aging conditions except at 150°C for 24 h. At this condition, SnPb showed IMC thickness comparable to SAC305 solder and was higher than other solders.

The combined sequential reliability test of thermal cycling aging followed by board level drop test for lead-free SnAgCu soldered assemblies were investigated. Interfacial IMCs, Kirkendall voids formation and interconnect failure mode are studied subject to TC aging. Kirkendall voids were observed with Ar+ sputtering etching. The failure sites and mechanism were examined and correlated with IMC and void formation. Significant decrease of drop life was observed for both SAC/ENIG and SAC/Cu-OSP assemblies after thermal cycling aging. Growth of Kirkendall voids and IMC significantly weakened the solder joint interface during TC aging. Drop impact crack path changed from the IMC to the IMC/Cu interface.

Abstract:
Exposure of lead free solder joints to high temperature isothermal aging conditions leads to microstructure evolution, which mainly includes coarsening of the intermetallic (IMC) phases. In our previous work, it was found that the coarsening of IMCs led to degradation of the overall mechanical properties of the SAC solder composite consisting of β-Sn matrix and IMC particles. However, it is not known whether the isothermal aging changes properties of the individual β-Sn and IMC phases, which could also be affecting to the overall degradation of properties. In this study, the aging induced variations of the mechanical properties of the β-Sn phase, and of Sn-Cu IMC particles in SAC solder joints have been explored using nanoindentation. SAC solder joints extracted from SuperBGA (SBGA) packages were aged for different time intervals (0, 1, 5, 10 days) at T = 125 °C. Nanoindentation test samples were prepared by cross sectioning the solder joints, and then molding them in epoxy and polishing them to prepare the joint surfaces for nanoindentation. Multiple β-Sn grains were identified in joints using optical polarized microscopy and IMCs were also observed. Individual β-Sn grains and IMC particles were then indented at room temperature to measure their mechanical properties (elastic modulus and hardness) and time dependent creep deformations. Properties measured at different aging time were then compared to explore aging induced degradations of the individual phases. The properties of the individual phases did not show significant degradation. Thus, IMC coarsening is the primary reason for the degradation of bulk solder joint properties, and changes of the properties of the individual phases making up the lead free solder material are negligible.

Abstract:
Solder micro-bumps, which serve as interconnects between stacked dies in 3D electronic packages, are typically very thin (25μm or less) and contain a high proportion of intermetallic compounds (IMCs). This makes micro-bumps brittle, and prone to fracture, particularly under drop conditions. In this paper, the fracture mechanics and mechanisms of SAC305 solder micro-bumps attached to Cu metallizations are studied as functions of the proportion of IMC in the joint. The effects of IMC content, IMC composition (i.e., the relative amounts of Cu3Sn and Cu6Sn5), strain rate, and mode mixity on both fracture toughness and fracture mechanism were investigated. The fracture mechanisms were studied via quantitative fractography. It was found that fracture toughness decreases dramatically (∼80%) with increase in IMC content (from ∼22% to 100%IMC). In all samples, the majority of the fracture surface comprised IMC/Sn interface failure, which constitutes the predominant fracture mechanism. With increasing aging, the proportion of ductile fracture of Sn decreases, fracture through Cu6Sn5 cleavage increases, and more Cu3Sn/Cu6Sn5 interface failure is observed. In general, bulk fracture properties of Cu3Sn plays little role in the fracture process. Thin joints also frequently display an alternating crack path between the two solder-substrate interfaces with the crack transitioning from one interface to the other, through the intervening Sn. Such crack transition between two surfaces increases with increase in IMC content, as long as there is intervening Sn, and may be utilized to improve the fracture toughness of thin joints. Finally, joint fracture toughness decreased with increase in both strain rate and mode mixity.

Full text
Abstract:
Abstract Cu wires were bonded to AlSi (1%) pads, subsequently encapsulated and subjected to uHAST (un-biased Highly Accelerated Stress Test, 130 °C and 85% relative humidity). After the test, a pair of bonding interfaces associated with a failing contact resistance and a passing contact resistance were analyzed and compared, with transmission electron microscopy (TEM), electron diffraction, and energy-dispersive spectroscopy (EDS). The data suggested the corrosion rates were higher for the more Cu-rich Cu-Al intermetallics (IMC) in the failing sample. The corrosion was investigated with factors including electromotive force (EMF), self-passivation of Al, thickness and homogeneity of the Al-oxide on the IMC, ratio of the Cu-to-Al surface areas exposed to the electrolyte for an IMC taken into account. The preferential corrosion observed for the Cu-rich IMC is attributed to the high ratios of the surface areas of the cathode and anode that were exposed to the electrolyte, and the passivation oxide of Al with the lower homogeneity. The corrosion of the Cu-Al IMC is just a manifestation of the well-known phenomenon of dealloying. With the understanding of the corrosion mechanisms, prohibiting the formation of Cu-rich IMCs is expected be an approach to improve the corrosion resistance of the wire bonding.

Abstract:
Abstract Cu-Sn composites coatings by cold spray with wide ranges of particle size and shape (round to flake) were investigated regarding their intermetallic compound (IMC) formation. It was found when certain size and shape combination of Cu-Sn composite raw materials were employed, the embedded Cu-Sn IMCs such as Cu6Sn5 and Cu3Sn were observed even in as-sprayed states without additional heat treatments. These results implied that the impact energy of colliding particles of the cold spraying could be enough to activate IMC compounding process. It seems that this can be also true in several composite systems that have relatively low activation energy of IMC compounding. After post annealing, the Cu6Sn5 formed in as-coated state were transformed into the Cu3Sn phase and the residue of unreacted Sn particles were fully changed into the Cu3Sn phase (Cu6Sn5 →Cu3Sn). These conversion processes also depended strongly on the choices of the shape and size combinations of Cu and Sn particles.

Abstract:
Intermetallic (IMC) layers (Cu6Sn5 and Cu3Sn) are an essential component of a solder joint for good metallurgical bonding. However, the mechanical and physical properties of IMC layers differ significantly from the solder and substrate, and excessive IMC layers can lower the reliability of solder joints due to their brittle nature. Moreover, continuous miniaturization of packages and joints has increased the volume fraction of IMCs to a point where smaller joints could be completely composed of IMCs. Further miniaturization of joints may result in statistical grain size effects. One of the most common types of IMCs in microelectronic joints is Cu6Sn5, which is formed in a variety of bonding materials with different compositions of Sn, Cu, and Ag. Due to its large percentage of volume in solder joint; to predict the reliability of micro solder joints, it is necessary to characterize single crystal Cu6Sn5 IMC completely. This study reports the information on grain growth orientation and elastic-plastic properties such as young’s modulus, hardness, yield strength and strain hardening exponent of single grain of Cu6Sn5 in Sn-3.5Ag/Cu solder alloy system. IMCs materials were grown using reflow process using an experiment in which the time and temperature of reflow process was varied. Electron backscatter diffraction (EBSD) analysis was conducted after the reflow to measure the grain size and determine the preferred grain orientation. It was found that the growth orientation is in the orientation of the c-axis. Nanoindentation was carried out in 4 individual grains with different crystallographic orientation along normal to the growth axis to determine the elastic properties of Cu6Sn5 single crystal. Plastic properties were predicted using the nanoindentation results and Dao reverse analysis model. The results indicate that the hardness for Cu6Sn5 grains with different orientation along normal to growth axis is statistically indistinguishable. Lower elastic modulus was observed for a grain with [010] direction parallel to the loading direction. Yield strength of a grain with (001) plane parallel to the loading direction was slightly lower than other grain orientations. Overall, the experimental results obtained were found to be within the range shown in the literature.
