可对离子迁移・绝缘电阻值进行高精度・高信赖性・高效率的评价。
从当今的地球・市场环境来看,省能源・铅/无卤素・小型轻量・低价格・高信赖等观点出发的, 新素材・新实装方法的研究开发・评价方法的重估是必须的。
J-RAS 公司把握市场的需要,为您提供容易操作而且可以进行高信赖性评价试验的,
新时代离子迁移实验装置。
简介:离子迁移实验装置是一种信赖性试验设备,原理为印刷电路板上给予一固定的直流 电压(BIAS VOLTAGE),经过长时间的测试(1~1000 小时)并观察线路是否有瞬间短路的 现象发生(ION MIGRATION),并记录电阻值变化状况,故又叫做 CAF 试验,绝缘阻力电阻 试验,或者是 OPEN/SHORT 试验,我们将其统称为绝缘劣化试验。(ION MIGRATION TESTING)
