Cov khoom siv tiv thaiv zoo li qub uas siv rau hauv cov txheej txheem tsim khoom ntawm PCBA kev ua haujlwm tuaj yeem raug cais raws li tib neeg electrostatic tiv thaiv qhov system, tiv thaiv - zoo li qub flooring, anti-static operating system thiab cov khoom siv tshwj xeeb.
Tib neeg txoj kev tiv thaiv hluav taws xob muaj xws li tiv thaiv- cov hnab looj tes zoo li qub, cov ris tsho ua haujlwm, cov kaus mom, hnab looj tes, thiab lwm yam. Qhov kev tiv thaiv tag nrho no muaj ob qho tib si electrostatic to thiab tiv thaiv kev ua haujlwm, thiab tag nrho cov khoom siv tiv thaiv zoo li qub yuav tsum feem ntau yuav hauv cov chaw tsim khoom lossis cov khw muag khoom.
Direct contact with electrostatic sensitive devices should wear anti-static wristbands, wristbands should have good contact with human skin, wristbands must be no irritation to the human body, no allergic effects, wristband system to ground resistance value should be in the range of 106 108Ω.
Anti- lub rooj lev zoo li qub yuav tsum tsis pub tsawg dua ob lub dab teg txuas, ib qho rau tus neeg teb xov tooj, lwm qhov rau cov neeg ua haujlwm soj ntsuam cov neeg ua haujlwm lossis lwm tus neeg siv.
Nkag mus rau qhov tiv thaiv- thaj chaw ua haujlwm zoo li qub lossis tiv tauj nrog SSD cov neeg ua haujlwm yuav tsum hnav khaub ncaws tiv thaiv- cov khaub ncaws ua haujlwm zoo li qub, tiv thaiv- cov khaub ncaws ua haujlwm zoo li qub yuav tsum ua raws li cov kev cai ntawm GB12014- Xyoo 2009. Nyob rau hauv ib puag ncig uas cov txheeb ze av noo ntau dua 50 feem pua, cov khaub ncaws ua haujlwm tiv thaiv zoo li qub tau tso cai xaiv cov khoom siv paj rwb.
Anti-static flooring is to effectively discharge human electrostatic through the ground to the earth as soon as possible, especially because of mobile operations and should not use wristbands of human electrostatic. At the same time, it can also discharge the static electricity on the equipment and work equipment. Ground anti-static performance parameters to determine both to ensure that in a relatively short period of time the electrostatic voltage down to below 100V, but also to ensure the safety of personnel, the system resistance should be controlled between 105 108Ω.
Cov ntaub ntawv uas feem ntau siv los tiv thaiv - static flooring yog raws li nram no:
Anti-cov roj hmab zoo li qub: kev tsim kho yooj yim, zoo heev los tiv thaiv- zoo li qub, tab sis hnav yooj yim.
PVC anti- zoo li qub yas flooring: anti- cov nyhuv zoo li qub yog qhov zoo, lub zog ntev ntev, dav siv.
Anti- cov ntaub pua plag zoo li qub: anti- cov nyhuv zoo li qub yog qhov zoo, siv tau yooj yim, tab sis tus nqi siab.
Anti-static movable flooring: Zoo tiv thaiv- zoo li qub, zoo nkauj, thiab tus nqi siab heev.
Tso cai siv terrazzo hauv av los ntawm kev kho tshwj xeeb, xws li ua ntej tso hauv av xaim network, carburizing lossis txau cov tshuaj tiv thaiv kab mob rau hauv av, thiab lwm yam. Anti- static terrazzo pem teb muaj lub neej ntev, tus nqi qis, thiab tsim nyog. rau cov nroj tsuag tshiab.
Anti-kev ua haujlwm zoo li qub yog hais txog qhov chaw ua haujlwm, cov kab ntau lawm lub cev, cov cuab yeej, cov hnab ntim khoom, cov tsheb thauj khoom thiab cov dej ntxuav, thiab lwm yam. uas txhua tus txheej txheem feem ntau yuav muaj kev sib cuag, sib cais lossis kev sib txhuam nrog cov khoom thiab cov khoom tiav. Raws li cov ntaub ntawv siv nyob rau hauv cov kev khiav hauj lwm saum toj no yog heev insulating roj hmab, yas, ntaub thiab ntoo, lawv yog heev yooj yim mus tsim hluav taws xob zoo li qub nyob rau hauv cov txheej txheem ntau lawm, yog li lawv yuav tsum tau kho nrog anti- zoo li qub, piv txwv li kev khiav hauj lwm. system yuav tsum muaj kev tiv thaiv - zoo li qub muaj nuj nqi.
Anti-Static operating systems suav nrog:
Anti-static table mat. The operating table are equipped with anti-static mats, surface resistance between 105 109Ω, and through the 1MΩ resistance and ground connection, turnover boxes, boxes and all other containers should be made of anti-static materials, and labeled with signs.
Anti-static packaging bags. All plastic bags for packaging circuit boards or devices should be anti-static bags. Surface resistance of 105 109Ω, in the circuit board into or out of the bag, the hands should wear anti-static wristbands.
Anti-static logistics car. Used to transport devices, components of special logistics vehicles, should have anti-static function, especially the logistics vehicle rubber wheels, should use anti-static rubber wheels, the surface resistance of 105 109Ω.
Anti-cov cuab yeej zoo li qub. Tshwj xeeb, hluav taws xob soldering hlau, rab phom soldering, thiab lwm yam yuav tsum muaj kev tiv thaiv zoo li - cov haujlwm zoo li qub, feem ntau cov hlau nplaum hluav taws xob yuav tsum tau ua haujlwm ntawm qhov hluav taws xob tsawg (24/36V), lub taub hau hlau soldering yuav tsum zoo hauv av.
Hauv luv luv, txhua yam khoom nyob rau hauv kev sib cuag nrog lub rooj tsav xwm Circuit Court lossis cov cuab yeej, suav nrog qhov siab - nrawm nrawm ntawm qhov chaw, yuav tsum muaj kev ntsuas tiv thaiv - zoo li qub. Tshwj xeeb tshaj yog SMT siab- txheej txheem tso chaw ceev, siab- kev ua haujlwm ceev ntawm cov cuab yeej yuav ua rau muaj hluav taws xob zoo li qub, cov khoom siv hluav taws xob electrostatic yuav muaj kev cuam tshuam.
