濕度敏感等級計算器

這一計算器對塑料器件分類等級進行指導,這些塑料器件對濕度引起的壓力敏感,這樣,在裝配焊接回流接頭以及進行修復操作時,能夠正確的存儲和處理它們。

如果您不知道產品的器件系列、產品線和IC封裝,請在本頁面頂部的搜索詢問部分輸入型號。如果這是一個有效型號,那么,搜索結果會返回您所需要的信息。以后綴“N”表示RoHS兼容型號。 "N".

濕度/回流敏感度分類

如果一個器件被分類為MSL 1,那么它對濕度不敏感,包裝被打開后,不再需要干燥包裝。

如果一個器件被分類為更高數字等級,那么,它對濕度敏感,必須按照J-STD-033進行干燥包裝。

如果一個器件被分類為Level 6,那么它對濕度非常敏感,干燥包裝還不足以提供足夠的保護。在進行回流焊之前,請參考Altera包裝標簽上的烘干時間。

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.
