Vehicular window assembly process with temperature control of the solder joint that attaches an electrical connector

A method for assembling a vehicular window assembly, the method comprising:

• providing a vehicular window assembly comprising a glass panel and an electrically conductive trace established at the glass panel;
• electrically operating a heating device to heat an electrical connector disposed at the glass panel to heat and melt solder disposed between the electrical connector and the electrically conductive trace to form a solder joint providing electrically-conductive connection between the electrical connector and the electrically conductive trace established at the glass panel;
• while electrically operating the heating device, capturing sensor data indicative of a temperature of the electrical connector and the solder using a temperature sensor and processing the captured sensor data at a data processor of an electronic control unit (ECU);
• based on processing of the captured sensor data, adjusting electrical operation of the heating device to adjust the temperature of the electrical connector and the solder during the soldering process that forms the solder joint;
• before electrically operating the heating device, positioning the electrical connector and solder at the electrically conductive trace established at the glass panel based on position data captured by a position sensor and processed at the ECU;
• and
• wherein the temperature sensor comprises an infrared (IR) temperature sensor that also functions as the position sensor.
