【正文】 uctive finger cots should be used for handling ESDs devices. 當(dāng)需要用手套或手指套時 , 只有棉手套 ,抗靜電 /導(dǎo)電手套或抗 靜電 /導(dǎo)電手指套可用來處理靜電敏感材料 . 2. People handling ESDS devices. They should use the gloves, finger cots or gloves with fang cots. 處理靜電敏感材料時 ,可只用手套 ,手指套或手套加上手指套 . 42 Storage Areas 儲存地區(qū) 1. When the storage shelving is not an ESD protected area or workstation, the ESDS devices shall be in ESD protective packaging. 若儲物架不是一個靜電防護(hù)區(qū)域或工作站 , 則靜電敏感 材料必須置於靜電防護(hù)包裝物中 . 2. The ground chain for trailers (for Wipe/finish good) enough to pletely contact with ground and keep the chain clean, replacing a new one if necessary. 裝載材料成品的推車必須要有接地鍊條 , 其長度要能 夠完全與地面接觸 , 並保持乾淨(jìng)整潔 , 若不潔淨(jìng)則必需 更換之 . 43 Mobile Equipment 可移動的設(shè)備 Mobile equipment (., carts, chairs,tables shall not generate electrostatic voltages greater than +/200V(TCP100V) within twelve (12) inches of unprotected ESDS devices during use. 可移動的設(shè)備 (例如 :車子 ,椅子 ,桌子 )在使用時若接近未受保護(hù)的靜電敏感材料 12 英吋以內(nèi)不得產(chǎn)生大於 +/ 200(TCP100V) 伏特之靜電壓 . 44 Methods for Minimizing Static Charging 低靜電的方法 Antistatic Solution 抗靜電液 Antistatic chemicals (antis tat solutions) can be used to prevent static charge generation on static generating/charging materials in the work or storage areas. During application of any antistatic chemical, the user must consider the following: 抗靜電化學(xué)物 (抗靜電液 )可以用來防止在工作或儲存區(qū)的靜電產(chǎn)生或充電物發(fā)生靜電充電 . 在使用任何抗靜電化學(xué)物時 , 使用者應(yīng)考慮下列 : 1. 抗靜電液要選擇不會污染靜電敏感材料者 . 2. 抗靜電噴劑或溶液不可用於能夠產(chǎn)生能量的電氣部份或設(shè)備上 . 3. 當(dāng)裝置或包裝體直接暴露在噴霧下時不可使用抗靜電溶液 . 4. 靜電溶液需要的程度以及使用頻率要根據(jù)在正常作業(yè)下使 用靜電伏特計來做靜電壓量測的結(jié)果來做決定 . 45 Methods for Minimizing Static Charging 低靜電的方法 Relative Humidity Control 相對濕度的控制 Relative humidity has a significant impact on the generation of static electricity and its control is remended where practicable. 相對濕度對靜電產(chǎn)生有很大的影響如有能力最好要加以控制 . Note: The remended minimum humidity is 40% . 註 : 建議最小的濕度為 40% . 46 Methods for Minimizing Static Charging 低靜電的方法 Training 訓(xùn)練 It39。s hand, through the user39。s hands rather than at the operator? 離子風(fēng)扇是否朝向處理材料的雙手 ,而非朝向 operator? 21 _____ Is an annual ESD system pliance check to the requirements of this standard being performed? 每一工作區(qū)域是否每年做一次檢查 ,看是否符合此靜電管制規(guī)格的要求 ? 22 _____When pliance to the daily, weekly, quarterly, semiannual, and/or annual checks is not continuously maintained, are the checks performed a double frequency? 如果任何定期的測量不通過其量測頻率是否增加一倍呢 ? 23_____ Are records of the ESD item checks maintained at least 2 years minimum requirement . 所有 ESD量測的記錄皆必須保存 至少二年 的要求 ? 24 ____ Does each ESD protective package have a contrasting ESD caution label? 是否每一靜電防護(hù)包裝都有一明顯的靜電警告標(biāo)示 25 _____Are the ESD caution labels legible to normal vision at a distance of three feet? 是否此靜電警告標(biāo)示 (籤 )在 3英呎的距離即可看得清楚 ? 26 _____When more than one ESD work surface is used at a workstation, is each surface individually connected to the ESD ground? 是否每一工作桌面或桌墊都有其個別的靜電接地 ? Check List 檢查表 (3) 50 27 ____ When conductive/highly conductive ESD protective work surfaces are used (., stainless steel), are they connected directly to ESD ground without a series resistor to insure they are continuously at ground potential? 不鏽鋼工作桌面是否直接接地 ,即不需連接 一 1 Mega 歐姆的電阻 ? 28_____When a floor grounding device (., drag chain, drag wire, conductive castor) is used to ground mobile ESD protected workstations, is an ESD protective floor or mat used? 當(dāng)移動性工作桌 ,車子被用來當(dāng)成處理材料的工作桌時 ,它們是否有靜電接地 ?及在有靜電地板的 工作環(huán)境 ? 29 _____Are all ESDS devices packed in ESD protective packaging, when not at an ESD protected area or workstation? 當(dāng) ESDS產(chǎn)品 (即 IC材料 )不在靜電防護(hù)區(qū)域時它們是否有在靜電防護(hù)包裝之內(nèi) ? 30_____Are the packing material do not Generate static voltage more than +/200 volts when operation? 所有包裝用的材料 ,在使用時是否不會產(chǎn)生大於 +/ 200v(TCP 100V)的靜電壓 ? 31 ____ Is applying or removing static generating tapes and labels to antistatic tubes, magazines and carriers with ESDS devices inside, performed? 當(dāng)有 IC材料在管子或盤子內(nèi)時 ,是否沒有做會產(chǎn)生大於 +/ 200v(TCP100V)靜電壓的撕膠布或貼膠 布的動作 ? 32 ____ Are all ESDS devices shipped and received in closed ESD protective packages, which are not opened except at ESD protected workstations? 是否所有 IC材料在運送時都有使用靜電防護(hù)包裝 ?且只有在靜電防護(hù)工作桌 (或區(qū)域 )才會打開它 ? 33_____When nonpliance to the requirements of this standard are found,are the nonpliance causes corrected and material held to QRA engineer for disposition? 當(dāng)有不符合此 ESD管制規(guī)要求時 ,是否有改正其原因並 扣留問題材料給 QRA工程師處理 ?
