摘要
采用平行微隙焊的方法,成功实现了5μm厚的Ni Cr合金薄膜与直径为0.15 mm的Ni引线焊接,可用于薄膜传感器外引线的互连。试验结果表明:采用大电流(100~60 A),短时间(0.5~2 ms)的规范,能够得到较好的焊接接头。并讨论了电极压力对焊接接头的影响,提出在焊接时应采用合适的电极压力。
The Ni Cr 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 Ni Cr 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.
