Kev ntsuas ntsuas ntawm Antistatic khaub ncaws siv hauv SMT cov kab ntau lawm
Hauv SMT (Surface Mount Technology) cov khoom siv hluav taws xob tso, hluav taws xob zoo li qub yog tsim los ntawm kev txav nrawm ntawm cov khoom siv thaum lub sijhawm ua haujlwm siab - ceev ntawm lub tshuab tso. Qhov hluav taws xob zoo li qub yog kwv yees li 600V. Qhov hluav taws xob zoo li qub no ua rau kev ua haujlwm tsis zoo ntawm cov khoom thiab tuaj yeem cuam tshuam ncaj qha rau kev sib xyaw ua ke, ua rau lawv ua haujlwm tsis zoo.
Antistatic khaub ncaws yog ib qho tseem ceeb antistatic khoom hauv SMT ntau lawm los txo cov hluav taws xob zoo li qub tsim los ntawm tib neeg lub cev. Nws yog ua los ntawm cov hlau conductive hlau (xws li stainless hlau xaim) sib xyaw nrog paj rwb, hluavtaws fibers, thiab lwm yam, thiab qee qhov yog ua los ntawm carbon fiber los yog cov khoom siv hluavtaws (xws li tooj liab complex fibers). Thaum rubbed tawm tsam lwm yam khoom, cov hluav taws xob zoo li qub tau tawm los ntawm kev sib cuag nrog tib neeg lub cev los ntawm cov khoom siv hluav taws xob los yog dissipated los ntawm corona tawm ntawm cov conductive fibers, yog li tiv thaiv hluav taws xob zoo li qub.
Txawm li cas los xij, hnav khaub ncaws antistatic tsis txhais hais tias hluav taws xob zoo li qub yog tswj tau tag nrho. Yog tias cov nyhuv antistatic ntawm cov khaub ncaws tau ua tiav los ntawm kev dyeing, ces cov khaub ncaws antistatic tsis txawv ntawm cov khaub ncaws zoo tib yam thiab tuaj yeem ua kom muaj hluav taws xob zoo li qub. Kev ntsuas kev tiv thaiv ntawm cov khaub ncaws ua haujlwm antistatic tuaj yeem tshawb xyuas seb cov khaub ncaws puas ua tau raws li qhov yuav tsum tau muaj ntawm GB12014-89 "Antistatic Work Clothes" los ntawm kev ntsuas qhov ntsuas tus nqi tiv thaiv- rau- taw tes. Ua ntej, cov khaub ncaws ua haujlwm antistatic yuav tsum tau muab tso rau ntawm lub rooj insulating nrog qhov chaw tiv thaiv tsawg kawg yog 10¹⁴ Ω thiab lub rooj yuav tsum loj txaus. Point-rau-point ntsuas qhov ntsuas yuav tsum tau ua tsawg kawg ntawm peb qhov chaw sib txawv, suav nrog cov seams ntawm cov ris tsho. Yuav tsum siv lub ntsuas ntsuas qhov hnyav (ACL-800). Qhov kev ncua deb ntawm ob lub electrodes ntawm lub 'meter' yuav tsum tsis pub tsawg tshaj li 300 hli, thiab cov axis txuas ob electrodes yuav tsum opposite rau axis ntawm cov tsoos tsho fibers.
