Abstract: The NiCr thin-films (5 mm thick) and Ni leads with 5 mm-diameters were successfully bonded using a parallel micro gap welding method for thin-film sensor interconnects. According to our experimental results, welding joints between the NiCr thin-films and Ni leads were achieved with strong currents (100~60 A) and short duration (0.5~2 ms). The tensile force is high enough. Effects of the electrode force on the welding quality were investigated. It is necessary to choose appropriate electrode forces during welding process.
