    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.
