湿度敏感等级计算器

这一计算器对塑料器件分类等级进行指导,这些塑料器件对湿度引起的压力敏感,这样,在装配焊接回流接头以及进行修复操作时,能够正确的存储和处理它们。

如果您不知道产品的器件系列、产品线和IC封装,请在本页面顶部的搜索询问部分输入型号。如果这是一个有效型号,那么,搜索结果会返回您所需要的信息。以后缀“N”表示RoHS兼容型号。 "N".

湿度/回流敏感度分类

如果一个器件被分类为MSL 1,那么它对湿度不敏感,包装被打开后,不再需要干燥包装。

如果一个器件被分类为更高数字等级,那么,它对湿度敏感,必须按照J-STD-033进行干燥包装。

如果一个器件被分类为Level 6,那么它对湿度非常敏感,干燥包装还不足以提供足够的保护。在进行回流焊之前,请参考Altera包装标签上的烘干时间。

MSL Baking Instructions

* Disclaimer

If you do not know the device family, product line and IC packaging of the product, type in the part number in the search query on the top of this page. If it is a valid part number, then the search result returns the information you need. A RoHS-compliant part number is denoted by the suffix "N".

Moisture/Reflow Sensitivity Classification

If a device is classified as MSL 1, it is not moisture sensitive and the device does not have to be dry packed again after the pack has been opened.

If a device is classified at a higher numerical level, it is moisture sensitive and must be dry packed in accordance with J-STD-033.

If a device is classified as Level 6, it is extremely moisture sensitive and the dry pack will not provide adequate protection. Please refer to Altera's packing label on the baking time before reflow soldering.
