化合物半导体市场需要高纯度的铟。今天,我们将讨论 "高纯度 "在铟方面的实际含义,以及如何验证这一点。
在大多数应用中,通常购买纯度为 4N(99.99%)的铟。作为焊料互连,4N 纯度的铟就可以了。4N5(99.995%)和 5N(99.999%)纯铟在低温密封等应用中最为常见;这些应用真正利用了铟元素最独特的特性--如冷焊接、延展性和接近绝对零度的柔软性。化学反应和物理沉积工艺要求更高的纯度:6N(99.9999%)和 7N(99.99999)。
When you’re dealing with critical applications, you should demand verification of the purity of your raw materials. At Indium Corporation, this is standard documentation for high purity indium. A full Certificate of Analysis is included in each shipment, with a breakdown of elemental impurities.
