Abstract(s)
Teste de eletrónica no contexto de produção é um passo fundamental no ciclo de vida de um circuito antes do mesmo chegar ao seu consumidor, no entanto, facilmente é negligenciado durante a conceção do produto e pode-se tornar um custo adicional após serem detetados erros e até prejudicar a perceção da qualidade dos produtos da empresa se os mesmos forem detetados demasiado tarde. Tecnimaster FL é uma empresa de produção de eletrónica com uma equipa de engenharia externa, sem equipa de teste dedicada e com um sistema de teste preparado para testes automáticos com uma interface de utilizador simples, como tal, um acordo foi realizado para desenvolver um teste para um produto novo não lançado usando os recursos da empresa. Esta tese irá explorar um exemplo de teste desenvolvido para esse produto não lançado e demonstrar o que é necessário desenvolver, compreender e melhorar para testar a maioria do hardware do produto e garantir que um teste funcional e estrutural mínimo será realizado antes do mesmo chegar ao seu cliente. Durante a tese, múltiplos conceitos relacionados com teste e desenvolvimento de hardware serão explorados e finalmente uma análise de custo e tempo será realizada como prova do valor que um departamento dedicado a teste pode trazer a qualquer empresa que desenvolva produtos eletrónicos.
Electronic test in the context of production is a fundamental step in the life cycle of a circuit before it gets to its consumer, however it gets easily neglected during the conception of the product and can become an aggravated cost after errors are detected and even damage the perception of the quality of the companies’ products if they are detected too late. Tecnimaster FL is an electronics production company with an external engineering team, no dedicated test team and a test system ready for automatic tests with a simple user interface, as such an agreement was made to develop a test for a new unreleased product using the companies’ resources. This thesis will explore an example of a test developed for that unreleased product and demonstrate what needs to be developed, understood and improved in order to test most of the products’ hardware and ensure that at least a minimal functional and structural test will be performed before the product reaches the client. During the thesis, multiple concepts related to test and hardware development will be explored and finally a cost and time analysis will be made as a proof of the value a department dedicated to test can bring to any company that develops electronic products.
