METHOD FOR JOINING AUTOMOBILE WINDOW GLASS TO ELECTRICITY SUPPLY TERMINAL

摘要

Disclosed is a method that is for joining an automobile window glass to an electricity supply terminal and that contains: a first step wherein, using a lead-free solder alloy, a solder layer is formed by heat welding to a predetermined location on a conductive wire formed on the surface of the automobile window glass; a second step for forming a solder layer by heat welding to the terminal seat of the electricity supply terminal; a third step for positioning the surface of the solder layer formed in the second step to the solder layer formed in the first step; a fourth step for further heating both solder layers using a heater having a controlled heating temperature, thus welding and joining both solder layers together; and a fifth step for cooling by controlling the cooling temperature.
