ESD测试作业指导书

ESD Testing Work Instruction

1. 环境控制I. Environmental Control:

1) 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. 2) 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.

2. 个人接地线系统Personnel Grounding System

1) 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.

2) 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.

3) 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.

4) 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

3. 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 1) 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 \

2) 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.

3) 数字显示器上第二行显示了与测试材料之间的测量距离为25mm（1英寸）The

recommended measurement distance to the charged material is 25 mm (1inch) as displayed in the second row of the digital display.

4) 监测材料电压显示在第一行，在LED条上也有如图2所示：The voltage of the

monitored material will be indicated in the first row and also by the LED bar. See

figure 2.

5) 记录测量结果并反馈到相关部门，以便针对合格测量结果采取适当的措施Record the

measurements and feed back to the concern department to take proper actions regarding non-conforming measurements.

（规格说明：静电电压等于或小于100伏）(Specification: Static Voltage = / < 100 volts) 备注：在一些设备较隐敝的地区,则可以不用遵守静电电压小于100伏的要求当设备被密封或卷起时,不易受静电电压影响。Note: Areas where most of the devices are still sealed can be exempted to the static voltage requirement of < 100 volts . Devices are still safe to static voltages when sealed and reeled.

利用709静电传感器或其它同类检查器。Using 709 Static sensor or equivalent checker 1) 用其它物品磨擦被测试的原料或物体，比如： Rub the material or the object under test

with other materials e.g. glass, plastic, etc.

2) 在打开ON键将原料置于LO位置测量静电电压前，执行\命令，

然后,压下电池开关/零开关在ZERO位置,直到屏幕显示为000Perform the \sensor\ the material by turning \the LO position , then depress and hold the battery/zero switch in the ZERO position until the display shows 000.

备注：当握住传感器时，传感器操作员应与一个接地点相连（地线系统）将指向传感器远离正归零的检测体表面。Note: While holding the sensor the operator of the static sensor should contact a known ground point (grounding system) and point the sensor away from charged surfaces while zeroing.

3) 在对原料进行静电电压测量时，（在约有10英寸远的位置）将传感器指向被检测的

物体和材料。In taking the static voltage measurement of the material, point the sensor (at a distance of about 10 inches) toward the object or materials to be measured.

4) 如果传感显示超出了范围（如：显示为1），调到HIGH范围后，重新归零。If the sensor

is over ranged (i.e., display reads 1….), switch to HIGH range and re-zero.

5) 观察显示屏,把物体移向传感器，直至达到一英尺的最小距离。避免传感器接触到物

体或原料。如图3所示：Move the sensor toward the object while observing the display until a minimum distance of one inch is reached. Avoid touching the object/materials with

the sensor. See figure 3.

6) 记录测量结果并反馈到相关部门，以便针对不合格测量结果采取适当的措施（规格

说明：静电电压等于或小于100伏）Record the measurements and feed back to the concern department to take proper actions regarding non-conforming measurements. (Specification: Static Voltage = / < 100 volts)

备注：静电电压等于仪表上的数值与传感器和物体之间距离（英尺数）的乘积。
