Recuperação de kits do laboratório de electrónica digital

Abstract

This work was developed with the purpose of studying, based on principles of electronic engineering and laboratory resource management, strategies for the recovery and main tenance of equipment used in the laboratories of the Department of Electrical Engineering of Faculty of Engineering at Eduardo Mondlane University. The project specifically fo cuses on the analysis and rehabilitation of units of three critical device cathegories: the Bungard CCD/ATC kit, the Logic Tutor, and the Micamaster MAT980, which are currently inoperative or in deteriorated condition. The main objective is to ensure the operational functionality of these devices, promoting their reuse and extending their lifespan, thereby providing adequate conditions for students’ practical training and reducing the costs as sociated with acquiring new equipment. To achieve this, an experimental and applied methodology was adopted, involving a specialized bibliographical review on electronic equipment maintenance techniques, in-depth technical diagnostics, development of spe cific recovery plans, and the execution of repairs, including component replacement and circuit board redesign. In addition, the project included functionality tests to validate the performed interventions and the preparation of detailed technical documentation, which will serve as a guiding protocol for future laboratory maintenance operations, or the com pletion of the current ones. Through this study, not only was possible to repair a number of the specified units, but it was also possible to showcase a model for laboratory resource management, contributing to the improvement of practical teaching quality, institutional fi nancial optimization, and the mitigation of environmental impacts resulting from improper disposal of electronic waste.
