光敏類(lèi)元器件濕敏等級(jí)介紹
MSL: 通常封裝完的IC,膠體或Substrate PCB 在一般的環(huán)境下 會(huì)吸收濕氣,造成IC在過(guò) SMT回流焊時(shí),發(fā)生“爆米花”(POPCORN)的狀況。濕氣敏感性等級(jí)(Moisture Sensitivity Level,MSL) 被用來(lái)定義 IC 在吸濕及保存期限的等級(jí),若IC超過(guò)保存期限,則無(wú)法保證不會(huì)因吸收太多濕氣而在SMT回 流焊時(shí)發(fā)生 POPCORN現(xiàn)象。因此對(duì)于超過(guò)保存期限的 IC 要進(jìn)行烘烤。
