Avaliação dos tempos de teste de produtos eletrônicos

Abstract

The production line concept introduction by Henry Ford, brought a great enhancement in the resource usage efficiency and transformation during the industrial process. Afterwards Ohno (1988) presented that during the industrial process all the waste should be removed from the process. Ohno also explains that waste is any activity that do not aggregate value in the final product. As a production test do not aggregate value, it simply ensure the product reliability, this paper has the purpose to develop a methodology to evaluate, identify and reduce the longest tests time of an electronic test sequence without decrease the product quality. Based on the instrument driver s utilization is possible to identify opportunities points to be executed concurrently (parallelism). The execution of two or more tests in parallel make possible the time reduction of the whole product test. One baseline of times and results were created to act as a benchmark and based on statistical process control indexes such as result mean and standard deviation and also the test acceptance limits cpk index, it will be possible to confirm the methodology efficacy and efficiency. Besides the methodology, the paper also refers the analysis and automation tools that were created during the time optimization project.
