Lub luag haujlwm ntawm cov nplais antistatic hauv cov txheej txheem ntawm SMT khoom siv
Lub luag haujlwm ntawm cov nplais antistatic hauv SMT cov khoom tau txais cov txheej txheem. Nrog rau txoj kev loj hlob sai ntawm cov khoom siv hluav taws xob tiv thaiv kev lag luam, tshwj xeeb, kev tsim kho me me ntawm cov khoom siv thiab kev sib xyaw ntawm kev sib xyaw ua ke tau txuas ntxiv. siv. Nws cov hluav taws xob hluav taws xob feem ntau yog 50V txog 100V. Nws muaj ultra-high-speed, high-zaus IC cov cuab yeej nrog kev sib koom ua ke ntau dua thiab yog rhiab rau hluav taws xob zoo li qub. Qee cov khoom siv VMOS muaj qhov ntsuas hluav taws xob ntawm 30V nkaus xwb, uas tso rau pem hauv ntej stricter electrostatic tiv thaiv rau cov txheej txheem tsim cov khoom lag luam uas muaj cov khoom siv hluav taws xob saum toj no.
Thaum lub sijhawm tsim cov khoom siv hluav taws xob, electrostatic tawm tuaj yeem hloov cov yam ntxwv ntawm cov khoom siv hluav taws xob, ua rau muaj kev puas tsuaj lossis tsis ua haujlwm, thiab ua rau kev puas tsuaj rau qhov khoom kawg lossis kev siv txawv txav. Cov kws tshaj lij txheeb ze tau ua tiav cov txheeb cais. Qhov khoom nruab nrab poob ntawm qhov hluav taws xob zoo li qub yog li ntawm 8-33%. Kev tsim txom ntawm anti-static yog qhov zoo heev, yuav ua li cas tiv thaiv cov khoom hluav taws xob hauv cov txheej txheem ntau lawm? Cov kws tshaj lij ntseeg tias kev ua raws li hauv qab no yuav tsum ua kom tau zoo:
1. Qhov av los tiv thaiv cov nyom;
2. Chaw nres tsheb tiv thaiv kev tiv thaiv zoo li qub;
3. Qhov grounding tsis kam yog tsawg dua 4ohms;
4. Qhov ntsuas kub thiab ntsuas cua sov: 20-30 ℃, txheeb ze av noo 30-70%;
5. Ionizer, zoo thiab tsis zoo ion cua;
6. Tib neeg lub cev tiv thaiv zoo li qub;
7, ntim khoom siv lub hnab ntim khoom los tiv thaiv zoo li qub, thawv ntawv tiv thaiv zoo li qub, cov thawv ntim khoom tiv thaiv zoo li qub thiab lwm yam.
Xyoo dhau los ntawm kev tshuaj xyuas thiab tshawb xyuas cov ntsiab lus ntawm cov txheej txheem khoom siv hluav taws xob, peb lub tuam txhab tau pom tias thaum SMT cov txheej txheem ntau lawm, ntau cov ntsiab lus ntawm kev tiv thaiv electrostatic xav tau zoo dua. Piv txwv li: daim kab xev npog ntawm SMT daim kab xev (CoverTaper) tsis ncav cuag qhov zoo tshaj plaws antistatic impedance (105 ~ 8ohms), SMT txais zaj duab xis tsis yog antistatic, lub paj rwb ntim khoom ntim lub hnab tsis yog antistatic, thiab steel mesh so daim ntaub ntim hnab Lub tshuab hluav taws xob zoo li qub thiab lwm yam ... Cov kev tshwm sim no tsis yooj yim kom nyiam mloog tuaj yeem pom nyob txhua qhov chaw hauv cov txheej txheem ntau lawm. Lub zog hluav taws xob muaj peev xwm muaj peev xwm tsawg li ntau txhiab thiab volts txij li kaum tawm txhiab tus ntawm volts. Cov tshwm sim no Muaj zais kev phom sij ntawm electrostatic kev tawg.
Kev saib txog cov ntsiab lus no, peb txuas ntxiv tshawb nrhiav thiab ua tiav kev tshawb fawb tshwj xeeb. Nyob rau lub sijhawm ib nrab xyoo 2007, thaum kawg peb tau pom tias yog qhov kev ua haujlwm tau zoo tshaj plaws hauv tebchaws-antistatic daim kab xev thev naus laus zis yog thov rau lwm qhov txiaj ntsig qhov qub "SMT splice zaj duab xis" Kev sib xyaw ntawm ob yuav zoo dua raws li qhov yuav tsum tau ua rau kev tiv thaiv electrostatic hauv cov khoom siv hluav taws xob. cov txheej txheem. Txawm li cas los xij, thaum lub sijhawm ua haujlwm, ntau qhov nyuaj tau ntsib. Cov teeb meem lawv tus kheej tsis yog antistatic mus tas li, cuam tshuam txog qhov kub thiab txias thiab qhov cuam tshuam, thiab kev sib txhuam tsis sib haum (cov no yog cov txiaj ntsig ntawm Ke Hongjian), thiab qhov nyuaj tshaj plaws yog kev siv "SMT zaj duab xis" Cov ntaub nplaum. Txhawm rau kom ntseeg tau ntawm SMT qhov tsis tau txais cov khoom siv, daim kab xev no tsim kom ua tiav qhov siab tshaj plaws. Yog tias muaj txheej txheem los tiv thaiv zoo li qub nyob sab nraum qab ntawm daim kab xev, daim nplaum nplaum rau ntawm cov ntaub nplaum tuaj yeem yooj yim mus rau txheej los tiv thaiv zoo li qub txheej. Nws yog cov ntaub nplaum uas lo tawm ntawm cov txheej txheem antistatic thiab cuam tshuam rau kev ruaj ntseg ntawm antistatic. Los ntawm cov txheej txheem cov yam ntxwv ntawm cov nplais tiv thaiv antistatic (zoo li pom hauv daim duab 1), yuav ua li cas tiv thaiv cov tshuaj tiv thaiv antistatic los ntawm kev tsiv ntawm thaj chaw nplaum? Qhov tseem ceeb tshaj plaws yog txhawm rau txhim kho cov txheej txheem antistatic ntawm txheej txheej ntawm kab xev kom ua cov xov molecular. Teb rau qhov teeb meem txuj ci no, pawg neeg tshawb fawb thiab kev tsim kho Kehong yuav tsis ntshai kev nyuaj, muab kev ua si tag nrho rau nws tus kheej qhov kev txawj ntse, sib txuas nrog kev siv technology txawv teb chaws, thiab tom qab ntau txhiab qhov kev sim tshawb fawb, thaum kawg kov yeej qhov kev nyuaj no! Nyob rau thawj ib nrab xyoo 2008, "SMT antistatic cov khoom siv tau txais zaj duab xis" (qhia hauv daim duab 2) tau dhau qhov kev soj ntsuam nruj los ntawm ntau lub tuam txhab muaj npe nyob hauv tsev thiab txawv teb chaws, xws li Huawei thiab Flextronics, thiab tau mus txog qhov hluav taws xob hluav taws xob hluav taws xob < 30v="" (saib="" daim="" duab=""> Txog tam sim no, los ntawm kev sib piv kev sib piv nrog cov khoom lag luam hauv tib qho kev lag luam thoob ntiaj teb, cov txiaj ntsig tau qhia tias cov khoom ua tau zoo ntawm Haiwei Dahang yog qhov zoo tshaj plaws, thiab cov khoom lag luam nrog cov teeb meem zoo tshaj plaws ntawm ntau yam ntsuas xav tau los ntawm EMS txheej txheem tau dhau los ua lag luam ntu ntawm ntu no. Tus Thawj Coj. Tam sim no, cov khoom lag luam zoo heev paub tab, ruaj khov thiab muaj nyob hauv cov khoom lag luam, thiab tau txais zoo los ntawm cov neeg siv khoom. Kev sib tawg ntawm cov teeb meem txuj ci no tau thaum kawg coj qhov kev nce nqi ntawm cov txiaj ntsig ntawm kev tsim khoom siv hluav taws xob!
Nrog kev tshwm sim ntawm cov ntaub ntawv thoob ntiaj teb, cov khoom siv hluav taws xob yuav dhau los ua neeg zoo dua, muaj kev ntseeg siab thiab tsim lag luam me, thiab cov tseev kom muaj rau kev tsim khoom hluav taws xob cov khoom lag luam yuav xav tau ntau dua. Hiway Aviation kam ua haujlwm nrog feem ntau ntawm cov neeg ua haujlwm tshawb fawb thiab thev naus laus zis hauv kev lag luam hluav taws xob tau muab kev ua si tag nrho rau nws cov tub ntxhais siv thev naus laus zis, them sai sai rau cov ntsiab lus, txhim kho teeb meem, kov yeej cov teeb meem hauv kev lag luam, muab cov kev pabcuam zoo, thiab ntsib tshiab cov kev sib tw nqa los ntawm cov khoom muaj txiaj ntsig zoo thiab xav tau khoom lag luam!
