MSL等級3 (level 3),如果零件暴露在攝氏溫度30°C與60%濕度以內的環境下,那麼其暴露的總時間就不可以超過 192小時 (其中需扣除IC半導體廠商的 24小時的曝露時間,所以SMT表面貼著廠就只剩下168小時(=192-24)的車間時間了),也就是說對於等級3的IC從真空包裝中取出後,就必須在168個小時內打件並過完Reflow (...
IPC/JEDEC defined a standard classification of moisture sensitivity levels (MSL's). The MSL's are expressed in numbers, with the MSL number increasing with the vulnerability of the package to popcorn cracking. Thus, MSL1 correspond to packages that are immune to popcorn cracking regardless ...
