Item Aplicação das ferramentas da qualidade como suporte para melhoria de processo de modem de fibra óptica: um estudo de caso em uma empresa do polo industrial de Manaus(2023-04-05) Baima, Maria Gilvane Santos; Oliveira, Fabian Bezerra de; http://lattes.cnpq.br/3460355721680055; Oliveira, Fabian Bezerra de; http://lattes.cnpq.br/3460355721680055; Santos, Katia Cristina de Menezes; http://lattes.cnpq.br/8746130584418173; Souza, José Geraldo de Pontes; http://lattes.cnpq.br/3583358046117558With the advances in the world market and competitiveness among business organizations, there was a need to insert the use of Quality Tools in organizations. Such tools were developed to help professionals understand the problems that occur in their daily lives, in order to find the root cause and propose appropriate solutions for them. In this sense, this research aims to analyze the causes of the main welding failures in the SMT process and propose improvement actions in the assembly of printed circuit boards for fiber optic modems, in an electronics industry in Manaus, through the organizational tool 5W2H. For this, a case study was carried out, through field research, in a company in the Industrial field of Manaus. And, for the prioritization of defects in the SMT process of Fiber Optic Modem production, the Verification Sheet and the Pareto Diagram were used. Among the results, it was identified that the largest number of defects is the failure of insufficient soldering in the T300/T301 component, totaling 81.2% of the defects found. To solve the defects, it was applied: the implementation of adjustment in the assembly coordinate of the components, creation of a new stencil with “overprint” and “step up” and increase in the assembly tolerance with variation of reading of the component terminal. In this way, the adoption of quality tools with the aid in the analysis and solutions of defects facilitated the monitoring of the process, as well as the reduction of product defects, in addition to minimizing rework, thus expanding the guarantee of product quality. and of the process.Item Aplicações com pastilha de peltier na eletrônica(2023-08-26) Lopes, Brenda da Silva; Souza, José Geraldo de Pontes e; http://lattes.cnpq.br/3583358046117558; Souza, José Geraldo de Pontes e; http://lattes.cnpq.br/3583358046117558; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Ribeiro, Laura Michaella Batista; http://lattes.cnpq.br/8632002394782219Physics is the science dedicated to researching and analyzing natural phenomena such as acoustics, optics, dynamics and electricity. Training in this area provides knowledge to understand the relationship between energy and matter in different dimensions, from atomic particles to the Solar System. Based on the applied studies, the beginning of research on temperature was chosen, then choosing applications on Peltier Tablets, which are devices based on the Peltier effect and are applied to produce a cooling or heating effect. This work addresses concepts involved in the operation of these devices such as: history of the Peltier effect and development of Peltier effect plates. A study is made based on the graphical and practical results. For this, a “mini refrigerator” refrigeration structure is implemented and measurements are made to determine the efficiency of the system. Finally, conclusions are presented about the study developed.Item Caracterização elétrica do diodo de sinal 1N4148(2023-02-23) Leão, Nervan dos Santos; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Souza, José Geraldo de Pontes; http://lattes.cnpq.br/3583358046117558; Ribeiro, Ewerton Andrey Godinho; http://lattes.cnpq.br/0187470129136467The objective of this work is the electrical characterization of the 1N4148 signal diode.

This system has the ability to remotely monitor the temperature, voltage and current through sensors and conditioning circuits to read the magnitudes related to the compressors. The system is presented through a prototype, consisting of an ESP 32 microcontroller that is responsible for calculating and transmitting data via the internet to a blynk cloud server on the blynk platform that was used to carry out the monitoring. As a final result, it was to provide a prototype capable of capturing and monitoring the variables of a compressor, allowing remote monitoring of tests, presenting results in real time, through a friendly panel. The results obtained from the simulations that were made in the work are strong, since it is confirmed that the system is able to read the values of the variables through the sensors and conditioned circuits, sending data using the ESP32 microcontroller, which through a monitoring interface, is able to present the results of the variables in real time, which concludes that the system can help in effective actions regarding equipment maintenance.
