Environmental stress screening (ESS) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to have a higher reliability than a similar unscreened population.

  • 環境應力篩選(Environmental Stress Screening,ESS)是指對產品施加環境與工作應力,如溫度、振動等,使得利用一般功能檢驗所無法測得之潛在疵病提前暴露出來,從而即早發現瑕疵而將之剔除,以達到品質管制的目的。 原先篩選代表傳統的品管篩選、鑄造件的非破壞檢驗(如X光、染色探傷等)與高壓容器的耐壓試驗等,針對電子產品之篩選使用環境應力,其汰弱功效顯著,在1979年後可靠度應力篩選(Reliability Stress Screening)漸成一獨立工作領域,其為ESS的擴充,是盛行於電子產業的品質與可靠度保證方法,除將在製程中因問題材料或不良工藝等所造成的瑕疵品剔除外,也可對此非設計疵病加以修改,以提高電子產品生產品質,滿足規格要求。
