Abstract


This paper presents a solution for optimizing the conformal coating process of electronic boards used in the aerospace industry by applying Lean Manufacturing principles and tools. The primary objective was to identify and reduce time and resource losses, directly impacting productivity and process efficiency. To identify and diagnose the root causes of waste, specific Lean Manufacturing tools were employed, including process flow analysis, Value Stream Mapping (VSM). The study highlights the types of waste identified according to the TIMWOOD framework such as waiting time and inefficient transportation and proposes practical solutions, such as increasing the capacity of the transport device and eliminating waiting times between protective coating applications. The results demonstrate a significant reduction in operation time and an increase in the number of boards processed simultaneously, leading to enhanced productivity and a 59% reduction in waste
