Electrostatic cim thiab Ionising cua blower txujci
Tus nqi xa tuaj yog tshwm sim vim muaj cov nqi hluav taws xob thiab hluav taws xob, yog li ntawd ob lub zog ntawm qhov txawv txav yog hu ua electrostatic. Qhov hluav taws xob tsis zoo li qub tsis yog hluav taws xob. Qhov hluav taws xob zoo li qub yog qhov sib npaug ntawm hluav taws xob. Nws yog ib qho zoo kawg nkaus hluav taws xob. Qhov hluav taws xob zoo yog qhov txhia chaw, txawm nyob hauv ib qho chaw uas tsis muaj kev tiv thaiv, tsis muaj hluav taws xob hauv txhua lub sijhawm. Nws tuaj yeem txo qhov uas muaj hluav taws xob zoo li qub. Qhov feem ntau kev tshawb, lub hom phiaj thiab kev ncaj qha mus sim nrog tshuaj ntsuam txog antistatic nrog cov khoom siv yog cov qauv zoo tshaj plaws. Tam sim no, tsis muaj ntau yam seev cev uas tuaj yeem kuaj cov khoom siv hluav taws xob hauv lub khw, thiab cov twj siv hluav taws xob tshuab hluav taws xob kom pom zoo cov khoom hluav taws xob zoo li cov nyuj. Cov ob yog txawv thiab yuav tsum tau muab sau tseg.
Nws yog pom zoo kom kuaj cov tshuaj antistatic rau semiconductor cheebtsam: Yug STACLEAN series LED antistatic tester, American ETS semiconductor antistatic tester, Taiwan Zhengmao LED nti qhia ntawv xeem, Nyiv Kikusui semiconductor xeem ntsuas, Agilent semiconductor xeem ntsuas, thiab lwm yam. Yog hais tias tus LED muaj peev xwm tsis zoo li qub tsis siab, koj tuaj yeem xav txog plaug tiv thaiv qee yam tshuaj tiv thaiv rau cov khoom hluav taws xob: xws li kev siv cov tshuaj thaiv txoj sia zoo li qub thiab cov tshuaj tiv thaiv kev tiv thaiv los tiv thaiv kev sib thooj, anti-static lev, thiab ua li ntawd. Tus antistatic Performance index ntawm cov ntshav tsuas tuaj yeem soj ntsuam nrog ib qho tshwj xeeb nruab nrab ntawm kev sib sim simulation tester, thiab tsis tuaj yeem kuaj ua ke nrog cov xuab zeb electrostatic ntawm hom kev tawm hauv tsev. Hauv qhov kev ntsuam xyuas antistatic LED, qhov hluav taws xob hauv hluav taws xob yuav tsum ncaj qha mus rau ob lub pins ntawm LED. Qhov pauv tawm ntawm kev ntsuas tau muaj kev cai nruj heev. Txawm hais tias qhov kev ntsuas ntsuas ncaj qha thov 10KV rau tib neeg lub cev, nws twb tsis paub meej. Tab sis hom ntawm electrostatic phom - lub lag luam yog tsis yooj yim rau ua rau tib neeg lub cev, cia nyob ib leeg ncaj ncaj tus txiv neej, lub txim tsis zoo.
LEDs muaj rau cov chav kawm ntawm cov khoom siv hluav taws xob thiab muaj cov qauv kev sib sim electrostatic tso tawm simulation. Qhov ntau thiab cov ntaub ntawv pov thawj nyob rau hauv lub ntiaj teb no yog: ANSI-ESDSTM 5.1.2-1999 ntawm International Electrostatic Association. JESD22-A114 / 115 ntawm Pawg Neeg Sib Koom rau Cov Khoom Siv Hluav Taws Xob (International Electronic Devices). Cov tub rog Asmeskas cov qauv "MIL-STD-883" muaj cov lus piav qhia ntawm qhov cuab yeej ntawm kev sib tw hauv static. Tib neeg lub cev: Thaum muaj hluav taws xob zoo li qub los ntsuas cov khoom ntsuas, muaj 330 ohm resistor yog siv rau hauv. Qhov no yog simulate tus nqi xaib thaum tus neeg tau ntsib nrog lub cuab yeej. Kev sib cuag ntawm tib neeg thiab tus kwv yog feem ntau kuj yog 330 ohms, yog li ntawd nws yog hu ua tib neeg lub cev hom. Mechanical hom: Nruab nrab hluav taws xob tau ncaj qha mus rau cov khoom siv hauv kev sim. Lub simulation cuab yeej mechanically hloov lub electrostatic nqi ncaj qha mus rau lub ntaus ntawv, yog li nws yog hu ua hom tsheb hom. Lub tshuab electrostatic them nqi hluav taws xob thiab cov pa tawm ntawm ob qho kev ntsuas cov cuab yeej kuj txawv me ntsis. Soj ntsuam ntawm tib neeg lub cev cov qauv kuaj yog feem ntau 8-10 lub sij hawm uas ntawm hom kev kho hom. Hauv kev lag luam LED, ntau lub tuam txhab tam sim no siv cov cim ntawm tib neeg lub cev qauv. LEDs yuav raug xa mus rau lub xeev tam sim no ntawm lub kos duab electrostatic classification (ANSI) tus qauv hluav taws xob class classification: 0 <250v antistatic="" muaj="" peev="" xwm="" heev,="" heev="" yooj="" yim="" rau="" electrostatic="" kev="" puas="" tsuaj,="" tsis="" zoo,="" tuag="" teeb="" yog="" tshaj=""> Nws tsis muaj kev muaj peev xwm tiv thaiv tsis tau thaum muaj xwm txheej. Chav kawm 1A 250-500V Lub peev xwm ntawm kev tiv thaiv tsis zoo, nws yooj yim puas los ntawm hluav taws xob muaj hluav taws xob, qhov tseem ceeb yog qhov tseem ceeb heev, tuag teeb feem ntau tshwm sim, thiab tsis muaj peev xwm muaj peev xwm nyob rau hauv cheeb tsam ib puag ncig. Hoob 1B 500-1000V tsis muaj peev xwm ua rau muaj kev muaj peev xwm thiab muaj kev puas tsuaj rau electrostatic. Qhov zoo yog pluag thiab tuag teeb puav tshwm. Muaj kuj yog ib cov degree ntawm antistatic muaj peev xwm. 1C qib 1000-2000V Lub peev xwm ntawm lub cev tsis zoo yog feem ntau tsis yooj yim los ntawm hluav taws xob muaj hluav taws xob. Muaj zog hluav taws xob muaj zog kuj tseem yuav ua rau hluav taws xob, thiab qhov zoo yog dav dav. Hoob 2 Xyoo 2000-4000V muaj peev xwm ua tau zoo thiab tsis raug rau electrostatic kev puas tsuaj. Feem ntau, hluav taws xob tsis muaj hluav taws xob yuav tsis ua kom lub LED thiab qhov zoo yog qhov zoo. Cov chav kawm 3A 4000-8000V muaj peev xwm ua tau zoo, tsis yooj yim los ntawm hluav taws xob muaj hluav taws xob, thiab yuav tsis ua rau cov neeg nyob hauv lub chaw muaj zog, thiab qhov zoo yog qhov zoo. Class 3B> 8000V Muaj peev xwm tiv thaiv tau zoo heev, nws yog ib qho nyuaj rau kev puas tsuaj los ntawm hluav taws xob hauv hluav taws xob, tsis muaj qhov tsis zoo ntawm electrostatic kev puas tsuaj, thiab qhov zoo yog qhov zoo heev. Raws li peb kev soj ntsuam nruam thiab nruam yav dhau los 5 xyoo, nrog rau qhov teeb meem nyob rau hauv lub xyoo dhau los, LED cov lag luam yog cov chaotic heev. Cov txheej txheem tiv thaiv teeb meem zoo li ntawm 250V mus rau 8000V, thiab ntau ntawm lawv tau sib xyaw nrog ntses. Tau sau. Rau tag nrho, qee tus LED antistatic qib yog tam sim no kev txhim kho sai, thiab lawv zoo tau zoo tuaj.
Ionising cua blower, tseem hu ua ion static eliminator, yog ib qho ntawm qhov tshem tawm zoo li qub. Lub hauv paus ntsiab lus ntawm cov ion kiv cua kom tshem tawm hluav taws xob hluav taws xob yog ua kom muaj hluav taws xob zoo los ntawm kev tawm tsam hluav taws xob los ntawm kev tsim cov huab cua ions. Ces, qhov kiv cua ionized ua tau li cas? Cov ion ntxias ionises saum huab cua. Cov txheej txheem ntawm kev tsim cov huab cua ions yog ua los ntawm peb txoj kev: thawj yog cua corona ionization nyob rau hauv muaj zog fais teb puag. Tsim cov ion positive thiab negative; thib ob, ua kom cua lwg rau hauv huab cua ions nyob rau hauv qhov kev txiav txim ntawm A thiab β rays; thiab peb, siab zog (X-rays) ua rau huab cua mus ionize lub hauv paus
