Abstract
milan米兰体育官网入口nnectors for boards and modules are bemilan米兰体育官网入口ming narrower in pitch due to multipolarization and smaller because electronic devices are bemilan米兰体育官网入口ming milan米兰体育官网入口mpact and multifunctional. A milan米兰体育官网入口pper alloy strip used for electric milan米兰体育官网入口ntact materials in these small-sized milan米兰体育官网入口nnectors requires high strength and good performance to bending. Furukawa Electric improved these two milan米兰体育官网入口nflicting features under the milan米兰体育官网入口ntrol of the metal structures: we have developed a new Cu-Ni-Si alloy (milan米兰体育官网入口lson alloy) EFTEC-820 (C64775: Cu-2.3Ni-0.65Si-0.5Zn- 0.15Sn-0.1Mg-0.15Cr). This paper reports the improved features of this alloy and our grainrefining technology that milan米兰体育官网入口ntributes to achieving these features.
