Resumo

Testes de estresse são destinados a avaliar o comportamento e desempenho de componentes eletrônicos quando submetidos a esforços térmicos, mecânicos, elétricos, pressão, químicos. Dentre os fatores que mais influenciam a confiabilidade e o desempenho de componentes eletrônicos se destaca o estresse térmico. A temperatura desencadeia uma série de mecanismos de falha que degradam o componente e que pode acarretar perda de desempenho ou ainda levar a falhas intermitentes ou catastróficas. Neste trabalho são apresentados os testes de estresse térmico, usualmente empregados pela indústria eletrônica para verificação da qualidade de componentes eletrônicos e a relação entre os mecanismos de falha e as condições de teste. São apresentadas algumas avaliações sobre os parâmetros que devem ser observados desde o planejamento até a conclusão do teste.
