    <p><span style='mso-bidi-font-family:Arial'>３．实际问题解决<span lang=EN-US><br>
    　　问题的解决包括：如果静电放电敏感元件（ESDS）在生产和维护期间暴露在外面，那么在这些元件附近，应防止电荷的积累，并且在运输和保管过程中，将这些元件按防静电放电的方法包装。<br>
    　　防止静电放电，有许多方法可以采用。最好的办法是满足要求且成本最低的方法，这样的方法对于不同的产品和不同的场合都是不同的。<br>
    <br>
    ４．静电放电保护区域（EPA）<br>
    <br>
    　　静电放电保护区域（EPA），有时指安全操作区，是任意一种静电放电控制措施的核心所在。在此区域中，静电放电敏感元件（ESDS）或电路板，或包含这些的组件，都可以很安全地工作，因为电荷的数量得到控制，而不会产生破坏性电压。这种区域中通常包含工作台或工作台组、工作站、自动插件机一类的处理设备或者一块生产区。EPA的范围必须清楚的标明，最好设置一围栏以防止未经允许的无关人员入内。EPA区域内应使用静电荷积累最小的材料，并且可使电荷以受控制的方式泄入到大地中。<o:p></o:p></span></span></p>
