Phil Zarrow: Brook, we've discussed handling solder paste from the refrigerator to the stencil printer, but there's a lot more to this story, particularly from the factory to the customer.
Brook Sandy-Smith: Right, when we talk about shelf life, we're usually talking about refrigerated shelf life. So, once your paste is in the refrigerator, how long can it sit there before you use it? But, a lot of times when we talk about that, we say storage less than 10°C, but there is this one little window, in the life of a jar of solder paste, where it's not at less than 10°C, and that's during shipping.So, when we prepare solder paste to be shipped out of our facility, we freeze it and we package up in a cooler with some ice packs, with the expectation that in the three to four days it usually takes for a package to be delivered, that the contents will never see ambient temperature.
菲尔-扎罗是的，现在你预计需要三到四天，这很合理，但可能会有延误--海关；可能会在飞机上运出，而楼上的机组人员与乘客发生口角，航班会延误--我们知道会发生什么......那么，对焊膏有什么影响？
Brook Sandy-Smith：所以，当你收到一包焊膏时，你不确定它发生了什么事，但你知道它不是在三四天内送到的，就是你收到焊膏的地方特别热。如果发生了意想不到的情况，首先要打电话给我们。我们将与您讨论您所使用的材料、它的运输方式以及您认为它暴露在温度下的天数。我们还可以安排在包装中加入温度条，这样在以后的运输中，您就可以知道包装中的物品是否达到了一定的温度。除此之外，您还可以查看焊膏。
菲尔-扎罗对了，我们要找的症状有哪些？
Brook Sandy-Smith：是的，如果你看到焊锡膏中助焊剂分离过多，你无法搅拌回去，这就是一个大问题。如果你看到任何结壳的部分，那也是一个信号。或者，有时会在表面形成一层皮，就像你把布丁留在外面一样。
菲尔-扎罗对
布鲁克-桑迪-史密斯暴露在空气中，皮肤就会有点发红。这也是一个信号。给铟打电话。看看我该怎么处理这块焊锡膏。
菲尔-扎罗所以我也会打电话给你们的救命啊帮帮我。布鲁克，我们在哪里可以找到更多关于焊膏处理的信息？
Brook Sandy-Smith: Well, you know we've talked about best practices for solder paste handling. You could also check out our application note on solder paste storage and handling guidelines, or I recently wrote a paper on what happens to solder paste in worst case shipping scenarios, which you can find on our website. Or, of course, you can just contact me directly at [email protected].
菲尔-扎罗布鲁克，非常感谢你。
