Análise da qualidade da soldagem do componente conector HDMI Mother Board Laptop

Abstract

This paper assessed the quality of HDMI connector component welding in laptop printed circuit boards (PCBs) based on IPC-A-610D standards. The study applied the PDCA method to identify and resolve issues related to insufficient solder barrel filling. Through X-ray analysis and metallographic tests, it was demonstrated that the automated reflow soldering process (SMT) meets normative requirements, effectively replacing the manual process.
