The growing demand for more compact, efficient, and reliable electronic devices has driven the use of Surface Mount Technology (SMT) in modern production lines. However, the solder paste deposition step remains critical, being responsible for a significant portion of process defects. In this context, this dissertation proposes the implementation of the Close Loop Print Control (CLPC) system as a strategy to reduce failures and improve quality in the production of electronic circuit boards. The study's general objective is to analyze the main defects related to solder paste deposition in an SMT line and propose improvements through the application of the CLPC system. As a method, a case study was conducted in a company located in the Industrial Hub of Manaus, involving the collection of quantitative data (via SPI system and technical reports) and qualitative data (interviews with operators and engineers). The research also included pilot tests, document analysis, and the practical implementation of the CLPC system with continuous monitoring of the production process. The results showed a significant reduction in defects such as solder bridges, missing components, and tombstone effect, as well as improvements in solder paste application uniformity, increased reliability, and positive acceptance by employees. The conclusion indicates that the application of the CLPC system proved effective in automating quality control. By integrating with interoperability and IoT principles, the CLPC aligns with Industry 4.0 practices, thereby contributing to increased efficiency, reduced rework, and enhanced reliability of the final product.
