Eficiência Produtiva em Linhas SMT: Aplicação da Métrica OEE e Estratégias de Melhoria na Indústria Eletroeletrônica da Zona Franca de Manaus

Abstract

This article presents the results of an applied study on production efficiency in a Surface Mount Technology (SMT) assembly line within the electronics manufacturing sector of the Manaus Free Trade Zone. Through the application of the Overall Equipment Effectiveness (OEE) metric, the study aimed to diagnose operational bottlenecks and propose targeted interventions using tools such as the Ishikawa Diagram and SMED method. Data collected between January and June 2023 revealed significant losses in availability and performance, leading to an OEE of only 22.4%—far below the world-class benchmark of 85%. Corrective actions including predictive maintenance, shift reorganization, and digital control via MES contributed to reducing downtime and improving operational governance. The study concludes that OEE is not merely a technical metric but a strategic tool for organizational transformation and Industry 4.0 integration.
