摘要：AbstractThis scientific paper conducts a study meant to improve the quality management of the thermosonic welding process of gold wires in the automotive industry. Within the large amount of electronic products manufactured worldwide, the gold wire bonding is the preferred technology for creating the needed interconnections in the microelectronic industry. In this paper, the quality management improving starts with an experimental research in the automotive industry, based on the gold wire thermosonic bonding, in terms of: conformal structuring, robustness and integrity of the electrical contacts. The experimental research is based on the processing parameters and on the independent variables and objective processing functions. In order to highlight the impact which one or more factors have on the quality of the thermosonic bonding, the dispersion analysis method was used. According to this, the importance of each factor, but also each factor's optimization, was underlined. The final goal was to reach a high reliability and quality of the finished goods.
