  1. 防止静电危害的措施the Measure of Preventing the Damage of ESD

  2. ESD (Electro Static Discharge) 1、静电发生在环境的四周 ESD happens around you 2、静电发生原因:(ESD happens in such situation)  ①接触(touching) ②剥离(peeling) ③摩擦(friction)等 3、人体带电量     湿度  60~90%RH10~20%RH (ESD in human body) (moisture)   ①绝缘地上行走       250V~12000V (walking on the ground)   ②地毯上行走        1500V~35000V (walking on carpet)   ③作业台作业100V~6000V (working on desk)

  3. ESD 静电破坏的种类damage of ESD 1、破坏broken・・电子部品完全损坏(completely broken) 2、特性劣化(characteristic deteriorating)潜在不良 (broken inside )   潜在不良时、会在客户的地方突然发生产品破坏: (The device with potential adverse effectswill become broken when customer is using it) ・修理的成本高 ( It takes high cost to repair ) ・公司的信用被破坏(Reputation of corporation will be broken)

  4. ・LSI不良品的 2/3 是静电破坏 ( 2/3NG products came from ESD damage) ・LCD全部品的耐静电电压1000V 以下 ( All LCD products will be damaged when ESD beyond 1000V )  特別是 LCD玻璃 耐电压不超过150V ( Especially LCD panel will be damaged when ESD beyond 150V ) 静电的基本对策(static protection) 1、环境湿度管理(moisture control)--55%~65%RH 2、静电消除器 ( antistatic air blower) 3、静电环、静电靴、静电手套、手指套 (earth-band,antistatic shoes,antistatic gloves,finger-cots) 4、作业环境接地 ( earth-connection )

  5. 接地棚架 CLOSETGROUNDED 静电环 earth-band HUMANGROUNDED 除电器 AIRBLOW 地板接地 FLOORGROUNDED 桌子接地 TABLEGROUNDED

  6. 接地线使用方法 Howto use earth connector 没有夹在正确的位置上 没有接地效果 NG 夹在正确的位置上 有接地效果 OK

  7. OK OK NG NG 静电环配帯方法 How to use your earth-band
