<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q2.itc.cn/images01/20240802/490ee00fdef4419cb82c12b782999ebd.jpeg" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在电子<span style="color: black;">制品</span>的生产、运输和<span style="color: black;">运用</span>过程中,静电防护至关重要。静电放电(ESD)可能<span style="color: black;">引起</span>电子设备的损坏、性能下降<span style="color: black;">乃至</span>失效。<span style="color: black;">因此呢</span>,<span style="color: black;">认识</span>并遵循静电防护的三个基本原则,<span style="color: black;">针对</span><span style="color: black;">加强</span><span style="color: black;">制品</span>质量、<span style="color: black;">保证</span>设备安全<span style="color: black;">拥有</span>重要<span style="color: black;">道理</span>。本文将从<span style="color: black;">掌控</span>静电源、切断耦合路径和加强静电防护管理三个方面,<span style="color: black;">仔细</span>阐述静电防护的基本原则。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">1、</span><span style="color: black;">掌控</span>静电源</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">静电源是产生静电<span style="color: black;">害处</span>的根源,<span style="color: black;">掌控</span>静电源是静电防护的首要任务。要<span style="color: black;">掌控</span>静电源,<span style="color: black;">必要</span><span style="color: black;">认识</span>静电起电的方式和影响<span style="color: black;">原因</span>,并采取相应的<span style="color: black;">办法</span>减少起电量。<span style="color: black;">平常</span>的起电方式<span style="color: black;">包含</span>接触一分离起电和感应起电,影响<span style="color: black;">原因</span>则<span style="color: black;">包含</span>材料性质、环境湿度、温度等。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">为了减小起电量,<span style="color: black;">咱们</span><span style="color: black;">能够</span>采取以下<span style="color: black;">办法</span>:</p>减少接触面积和接触压力,避免不必要的接触和分离;<span style="color: black;">选取</span>合适的材料,优先<span style="color: black;">运用</span>“静电带电序列”中相近或相同的材料;保持环境清洁,避免污染物附着在物体表面;<span style="color: black;">掌控</span>环境温度和湿度,避免静电荷的累积;如有<span style="color: black;">必须</span>,可采用中和技术消除静电荷。<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">2、</span>切断耦合路径</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">切断静电耦合路径是防止静电<span style="color: black;">害处</span>传播的关键。静电耦合路径<span style="color: black;">包含</span>电场耦合、磁场耦合和电磁场耦合等。静电屏蔽法是一种有效的切断耦合路径的<span style="color: black;">办法</span>,它<span style="color: black;">经过</span>利用封闭空腔导体的特性,将静电<span style="color: black;">敏锐</span>器件与<span style="color: black;">外边</span>电场隔离。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">静电屏蔽法分为内部屏蔽和<span style="color: black;">外边</span>屏蔽两种。内部屏蔽是将静电<span style="color: black;">敏锐</span>器件放入封闭空腔导<span style="color: black;">身体</span>,使<span style="color: black;">外边</span>电场<span style="color: black;">没法</span>直接<span style="color: black;">功效</span>于器件。<span style="color: black;">外边</span>屏蔽则是在静电<span style="color: black;">敏锐</span>器件<span style="color: black;">外边</span>设置导电层或导电网格,将<span style="color: black;">外边</span>电场引入大地,避免其对内部器件产生影响。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在<span style="color: black;">实质</span>应用中,<span style="color: black;">咱们</span>应<span style="color: black;">按照</span><span style="color: black;">详细</span><span style="color: black;">状况</span><span style="color: black;">选取</span>合适的屏蔽<span style="color: black;">办法</span>,并<span style="color: black;">重视</span>导体的接地处理,以<span style="color: black;">保证</span>屏蔽效果。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">3、</span>加强静电防护管理</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">静电防护管理是一个系统工程,<span style="color: black;">必须</span>综合<span style="color: black;">思虑</span>技术和管理两方面的<span style="color: black;">需求</span>。加强静电防护管理<span style="color: black;">能够</span>从以下几个方面入手:</p><span style="color: black;">创立</span>完善的静电防护制度,<span style="color: black;">知道</span>各<span style="color: black;">分部</span>的职责和任务;对静电<span style="color: black;">敏锐</span>器件进行<span style="color: black;">敏锐</span>度<span style="color: black;">实验</span>和等级划分,为防护手段<span style="color: black;">供给</span>依据;加强人员培训,<span style="color: black;">加强</span>员工的静电防护<span style="color: black;">认识</span>和操作技能;<span style="color: black;">定时</span><span style="color: black;">检测</span>和<span style="color: black;">守护</span>静电防护<span style="color: black;">设备</span>和设备,<span style="color: black;">保证</span>其正常运行;<span style="color: black;">创立</span>静电防护档案,记录防护过程和效果,为<span style="color: black;">连续</span>改进<span style="color: black;">供给</span>依据。<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">静电防护的三个基本原则是相互<span style="color: black;">相关</span>、相互<span style="color: black;">功效</span>的。<span style="color: black;">掌控</span>静电源是减少静电<span style="color: black;">害处</span>的<span style="color: black;">基本</span>,切断耦合路径是防止静电<span style="color: black;">害处</span>传播的关键,加强静电防护管理则是<span style="color: black;">加强</span>静电防护效果的<span style="color: black;">保证</span>。<span style="color: black;">仅有</span>全面<span style="color: black;">思虑</span>这三个方面,<span style="color: black;">才可</span>有效地防止静电<span style="color: black;">害处</span>的<span style="color: black;">出现</span>,<span style="color: black;">保证</span>电子<span style="color: black;">制品</span>的质量和<span style="color: black;">靠谱</span>性。<a style="color: black;"><span style="color: black;">返回<span style="color: black;">外链论坛:www.fok120.com</span>,查看<span style="color: black;">更加多</span></span></a></p>
