由於此類環氧樹脂在塑封時必須在150-180℃的高溫高壓下快速被注射進入精密模具腔體
，因此，塑封後的環氧樹脂層即使在 200倍的顯微鏡下也不存在微細氣孔，密封性良好，可以滿足各類半導體芯組的密封要求。

對於二氧化錳做陰極的片式鉭電容器，它的濕度敏感等級是 3級，而對於陰極采用3， 4 乙烯二氧噻吩【聚噻吩】導電高分子材料的片式鉭電容器，由於其陰極有較強的親水性，因此，它的濕度敏感等級為 5A級。

根據大量實際經驗統計
，濕度敏感等級小於 2jidedianziyuanjian，zaizhuanyunhechucunshijunwuxushiyongkeyifangzhixichaodezhenkongbaozhuang，zhishizuohaoqiangduhefangjingdianbaofengjiukeyimanzuyaoqiu。zheleidianziyuanjianjishizaikongqizhongbaolushijianjiaochang【一星期至數月】，如果不考慮引腳氧化和表麵活性下降對可焊性影響
，吸潮程度較低，對電性能基本沒有影響。而濕度敏感等級為3級以上的電子元件
，在轉運和儲存期間，必須使用可以防止吸潮的真空包裝，而且在濕度為 40%以上的空氣中暴露時間不能超過 24小時。如果因為任何原因致使該類電子元件在空氣中放置時間超過24xiaoshi

，內部吸附的水汽會迅速瞬間氣化，導致元件內部瞬間壓力過高，造成外包封層破裂或電性能失效。此類現象有人形象地成為‘爆米花’現象。造成這一現象的原因，主要是因為吸附的水分在氣化時
，一個體積的水會變為 40倍的摩爾體積，破壞性可想而知。
