Otimização do tempo de teste funcional de placa de circuito impresso montada para computador pessoal

Abstract

Increased competitiveness among the peer group has become increasingly important to the constant optimization of processes to consequently reduce manufacturing costs. The objective of this study is to assess the time involved in the functional testing phase of MBs produced in a company of the Industrial Pole of Manaus and propose improvements that lead to optimization of this phase. The actions taken with respect to optimizations led to the development system for capturing images to improve the analysis of downtimes and development of devices for testing, as well as the proprietary test system based on Linux to replace the previous system which relied of foreign partners. The percentage gains in the project was presented in four optimization proposals, the first being with the unification of the tests, the second with the test being performed on two board, the third with the replacement of the previous test by the system owner and end automation of the test device, which was demonstrated gains in each of the proposals. The results obtained after implementation of each proposal were positive and reinforce the need to apply scientific methods combined with creativity to achieve the optimization at any stage of the production process and closes the work suggesting ideas for future improvement of the system already optimized.
