正如之前发布的《Indiums特种合金和焊料表》中包含的数百种用作热界面材料的焊料合金,我们列出了每种合金的熔化温度。计算这些温度的方法是使用一种名为差示扫描量热仪的设备进行重复计算。
In this method, a small sample of the solder alloy is input into the system and slowly heated until the solder alloy melts. Throughout the reading, a graph is created, from which the solidus and liquidus temperatures are interpreted.
The graph appears as a steady baseline, and at the melting point of the solder alloy, a peak is generated (See Image). At the point where the peak first deviates from the baseline, the solder alloy has begun to melt. This is the solidus point. At the point where the deviation returns to the baseline, the solder alloy is completely molten. This is the liquidus point. The entire deviation period is defined as a phase change period.
扫描的容差与扫描速率有关。扫描速度越慢,读数越准确。典型读数的误差为 +/- 3:C。
If you have a question about the melting temperature of any of our solder alloys or a solder alloy you are purchasing from us, we will be happy to share the differential scanning calorimeter readings with you for your personal interpretation.
