Analysis of quality HDMI connector component welding in Mother Board Laptop

Abstract

The paper aims to assess the quality of HDMI connector component of welding in the welding process laptop printed circuit board meeting the eligibility criteria related to the filling of the solder barrel to pin through-hole components terminals as specified in international standard IPC-A-610D. For the development of the stages of research, it adopted the PDCA method, used for troubles hooting and application of continuous improvement, commonly used by different companies in the industrial segment worldwide. The results presented through analysis by X-RAY and metallographic test cross section, showed that the quality of HDMI welding through the automatic welding process by remelting meets the technical specifications of the standard of acceptability. Thus, left to perform the welding of this type of component in the manual process, passing it to weld using SMT technology.
