<p><span style='mso-bidi-font-family:Arial'>３．實際問題解決<span lang=EN-US><br>
問題的解決包括：如果靜電放電敏感元件（ESDS）在生產和維護期間暴露在外面，那么在這些元件附近，應防止電荷的積累，并且在運輸和保管過程中，將這些元件按防靜電放電的方法包裝。<br>
防止靜電放電，有許多方法可以采用。最好的辦法是滿足要求且成本最低的方法，這樣的方法對于不同的產品和不同的場合都是不同的。<br>
<br>
４．靜電放電保護區域（EPA）<br>
<br>
靜電放電保護區域（EPA），有時指安全操作區，是任意一種靜電放電控制措施的核心所在。在此區域中，靜電放電敏感元件（ESDS）或電路板，或包含這些的組件，都可以很安全地工作，因為電荷的數量得到控制，而不會產生破壞性電壓。這種區域中通常包含工作臺或工作臺組、工作站、自動插件機一類的處理設備或者一塊生產區。EPA的范圍必須清楚的標明，最好設置一圍欄以防止未經允許的無關人員入內。EPA區域內應使用靜電荷積累最小的材料，并且可使電荷以受控制的方式泄入到大地中。<o:p></o:p></span></span></p>
