Identificação de riscos e adequação do processo de impressão de solda (solder printer) às normas de segurança em um laboratório de manufatura avançada.

Abstract

A strategic partnership between a company from the Manaus Industrial Pole and the University of the State of Amazonas led to the creation of a specialization in Advanced Manufacturing and the establishment of a laboratory. This study focuses on investigating and proposing effective solutions to mitigate risks related to the operation of the laboratory's semi-automatic solder paste printing machine, known as the Solder Printer, crucial for assembling components on Printed Circuit Boards (PCBs). Considering the equipment's importation, there is a need for adaptation to Brazilian regulatory standards. Using an applied qualitative approach with the action research method, the study aims to identify and mitigate risks associated with the Solder Printer's operation, thereby providing a safe study and work environment for university students, researchers, and professors, in compliance with current safety standards. A checklist based on NR-12 was used for initial compliance verification. Subsequently, risk assessment was conducted following the methods of ABNT NBR ISO 12100:2013 and ABNT NBR ISO/TR 14121-2:2018 standards. Significant risks to user safety, such as cuts and crushing, were identified as results. Accordingly, a proposal with necessary adaptations was developed to mitigate identified risks and ensure compliance with Brazilian safety standards. The main suggested adaptations were implemented and validated, demonstrating effectiveness in risk reduction. It is concluded that the retrofitting of the semi-automatic Solder Printer was able to promote a safer environment, aligned with national regulations, and proved to be an economical and effective option for the manufacturing laboratory.
