Re-train the employee ESD annually ESD auditor will get special training and certification on ESD audit. Employees check their personnel grounding device daily before working shift Facility person check the ESD conductive tile monthly. Facility person check workbench dissipative mat monthly. Facility check production floor temperature and humidity daily QA conduct ESD audit monthly In-line QA spot-check the personnel grounding, device grounding daily. Equipment control room calibrate the personnel grounding checker monthly per the work instruction. * * Prepared by: Centra Tang 0. Content 1. Electrostatic and ESD protection basic 2.

ESD checking 1.1 Concept 静电(Electrostatic, static electricity): 静止未流动的电荷,能够停留在物体上; 1) .静电放电(Electrostatic Discharge, ESD) : 处于不同静电电位的两个物体间的静电电荷的转移 2). ESD中文含义：静电放电，因静电放电是静电 　　危害最主要的部分，所以慢慢ＥSD成为静电防 护代名词. 常见静电现象: 雷电, 复印 1.2 approach of generating static 1).接触分离, 2).摩擦, 3).剥离, 如撕胶纸 4).断裂, 5).传导, 6).感应, 7).其它: 热电, 光电, (+) (-) 1.3 Electrostatic sequence 1).两物体接触分离或摩擦后,排右面的带正电, 左面的带负电; 2).距离越远,摩擦电压越高; 3).距离越远,越容易产生静电; 静电序列应用时,只作参考, 不可作硬标准. 1).电压(静电压,摩擦电压): 伏特(V) 2).电流: 安培(A) 3).电量: 库伦(C) 4).表面电阻率/体积电阻率 欧姆/□ (Ω/□ ) 5).表面电阻/体积电阻: 欧姆(
