ESD测试作业指导书 ESD Testing Work Instruction 环境控制I.? Environmental Control: 所有工作区的相对湿度和温度应该保持在一定的范围并进行监测。一旦相对湿度百分比降至限度以下，立即通知QC和工程部进行处理。Relative Humidity and temperature in all works areas shall be monitored and maintained. If % relative humidity falls beyond the limits, immediately inform QC and engineering for disposition. 在将装配的产品置于无静电工作站前，在整个生产期间，使用离子发生器的生产线都应处于工作状态。离子发生器被安装在容易发生静电的区域。检测其衰减时间，小于或等于5秒钟，或者根据客户要求；检测平衡电压，小于或等于5伏，或者根据客户要求。Lines that uses Ionizers shall be in operations prior to handling of assembled products to static free work stations and shall be operating during the entire period of production. Ionizers are installed on areas where the chances of static build up occur. Check for the decay time , =/ 5 seconds or as required by the customer, and the balance voltage =/ 5 volts or as required by the customer. 个人接地线系统Personnel Grounding System 在生产线的不同站点,随机抽检十个员工。Randomly sampling at least 10 personnels from the different station of the production line. 员工手腕上带着静电手环，将静电手环与地线系统相连接让员工握着电荷分析仪的金属杆，如图1所示：With their groundstrap on their wrist, connect their groundstrap to the grounding system and let the personnel hold the metal rod of the Charge Analyzer . See figure 1. 让员工移动或跳跃起来，电荷分析仪则会监测出电压在人体上的波动情况。Let the Personnel move or jump. The charge analyzer will monitor the voltage fluctuation on the person. 从机器上读取人体所产生的电压，并记录所显示的数据。Read the voltage generated by the personnel from the instrument and record the measured data. 备注：产生的静电压等于0伏。Note: Static voltage generated = 0 volt 对所有原料、工作服、鞋子，手套进行检查。Checking of all Materials, Uniforms, Shoes and Gloves 利用711电荷分析仪或其它同类检测仪Using 711 Charge Analyzer or Equivalent checker 利用没有电极的711电荷分析仪，按下RANGE键选择适当的电压范围。Use the 711 Charge Analyzer without electrodes and select the appropriate voltage range by pressing the Range button. 用其它物品磨擦被测试的原料或物体，比如：玻璃、塑料等。监测静电电压和极性。Rub the material or the object under test with other materials e.g. glass, plastic, etc.. and monitor the static voltage and its polarity. 数字显示器上第二行显示了与测试材料之间
