Lub luag haujlwm ntawm cov khoom siv tiv thaiv zoo li qub nyob hauv SMT cov txheej txheem ua luam
Tam sim no, nrog txoj kev loj hlob sai ntawm hluav taws xob tivthaiv kev tsim khoom thev naus laus zis, tshwj xeeb tshaj yog miniaturization ntawm cov khoom siv thiab kev txhim kho tsis tu ncua ntawm kev sib koom ua ke, txuas nrog CMOS li nrog 0.15-0.25mm kev tsim cov txheej txheem tau siv dav. Nws cov hluav taws xob tawg feem ntau yog ntawm 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 ua kom nruj rau lub tshuab hluav taws xob tiv thaiv kev tiv thaiv rau kev tsim khoom thiab cov txheej txheem ntawm cov khoom uas muaj cov khoom siv hluav taws xob saum toj no.
Hauv kev tsim cov khoom siv hluav taws xob, cov hluav taws xob hluav taws xob muaj peev xwm hloov tau cov yam ntxwv ntawm cov khoom siv hluav taws xob, ua rau muaj kev puas tsuaj lossis ua tsis tiav, ua rau muaj kev puas tsuaj rau cov khoom kawg lossis tsis ua tiav ntawm kev siv ib txwm. Cov kws tshaj lij muaj cov txheeb cais tau teev tseg, thiab cov khoom poob nruab nrab los ntawm hluav taws xob zoo li ntawm 8-33%. Cov phom sij ntawm anti-static yog zoo li, 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 tau ua:
1. Los tiv thaiv zoo li qub hauv av;
2, kev tiv thaiv zoo li qub txuas ntawm chaw nres tsheb ua haujlwm;
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 electrostatic tiv thaiv;
7. Cov ntim tau txais coj los tiv thaiv cov hnab ntim khoom zoo li qub, lub thawv ntim khoom ntim khoom qis, lub thawv zoo li qub, thiab lwm yam.
Xyoo dhau los ntawm kev tshuaj xyuas thiab tshawb xyuas cov ntsiab lus ntawm cov khoom siv hluav taws xob tsim cov txheej txheem, peb lub tuam txhab muaj kev nkag siab tob thiab pom tias ntau cov ntsiab lus ntawm kev tiv thaiv electrostatic xav tau zoo dua hauv cov txheej txheem SMT ntau lawm. Piv txwv li, cov kab xev npog ntawm SMT cov khoom siv kab xev (CoverTaper) tsis tuaj yeem ncav cuag qhov zoo tshaj plaws los tiv thaiv zoo li qub (105 ~ 8ohms), SMT splice zaj duab xis tsis yog anti-zoo li qub, cov paj rwb fiber ntau ntim hnab tsis yog anti-zoo li qub, thiab cov steel mesh so daim ntaub ntim lub hnab tsis yog anti-zoo li qub. Hluav taws xob zoo li qub, thiab lwm yam ... Cov xwm txheej ntxaws ntxaws uas tsis yooj yim kom nyiam mloog yog pom nyob txhua qhov chaw hauv cov txheej txheem ntau lawm. Lub tshuab hluav taws xob tsim hluav taws xob muaj hluav taws xob tsawg tsawg li ntau txhiab, thiab muaj ntau li ntau txog li kaum txhiab ntawm qhov ntsuas, thiab cov xwm txheej no muaj qhov kev nyab xeeb zoo rau kev tawg hluav taws xob.
Nyob rau lub sijhawm ib nrab xyoo 2007, thaum kawg kuv pom tias yog tus tswv cuab tshiab ua haujlwm zoo tshaj li qub los tiv thaiv cov kab xev thev naus laus zis, raug siv rau lwm qhov kev ua haujlwm zoo tshaj" SMT splicing" ;, peb txuas ntxiv tshawb cov ntsiab lus thiab kev coj ua kev tshawb fawb tshwj xeeb." Zaj duab xis", uas sib xyaw ua ke ob mus rau ib qho, yuav zoo dua raws li qhov yuav tsum tau ua rau kev tiv thaiv electrostatic thaum ua cov khoom siv hluav taws xob tsim kev lag luam. Txawm li cas los xij, thaum lub sijhawm ua haujlwm, kev nyuaj siab tau ntsib. Qhov kev nyuaj ntawm nws tus kheej tsis yog lub caij ntev los tiv thaiv zoo li qub, tus nqi tsis kam, kub thiab av noo cuam tshuam thiab kev sib txhuam tsis kam thiab lwm yam teeb meem (cov npe no yog qhov zoo ntawm Kehongjian), thiab qhov nyuaj tshaj plaws yog kev siv" SMT splicing zaj duab xis" Txhawm rau kom ntseeg tau tias muaj kev cia siab ntawm SMT tsis-nres splicing, hom kab xev no tsim los ua kom tiav qhov siab tshaj plaws rau kev nplaum. Yog tias muaj txheej txheem tiv thaiv zoo li qub nyob rau sab nraub qaum ntawm daim kab xev, lub nplaum nplaum lub npoo ntawm cov ntaub nplaum yuav yooj yim rau cov txheej txheej los tiv thaiv zoo li qub, Ntawd yog, cov ntaub nplaum tiv thaiv tawm tsam txheej txheej, uas cuam tshuam rau kev ruaj khov ntawm anti -txhawb nqa. Los ntawm qhov kev pom ntawm cov yam ntxwv ntawm cov txheej txheem los tiv thaiv zoo li qub (raws li pom hauv daim duab 1), yuav ua li cas tiv thaiv cov txheej los tiv thaiv kev tiv thaiv zoo li qub txav mus los ntawm qhov chaw nplaum nplaum? * Nws yog ib qho tseem ceeb uas yuav tsum kho cov txheej txheem tiv thaiv zoo li qub ntawm cov khoom siv hauv qab ntawm cov kab xev los ua cov xov molecular. Teb rau cov teeb meem no, R& D pab pawg ntawm Kehong yuav tsis ntshai kev nyuaj siab, muab kev ua si tag nrho rau nws tus kheej cov tswv yim zoo, sib txuas nrog kev siv technology txawv teb chaws dhau los, thiab dhau ntau txhiab qhov kev sim rau * thaum kawg kov yeej qhov kev nyuaj no. ! Hauv thawj ib nrab xyoo 2008," SMT los tiv thaiv kev muaj yeej zaj duab xis" (raws li pom hauv daim duab 2) tau dhau los ntawm kev tshuaj xyuas nruj los ntawm Huawei, Flextronics thiab lwm cov tuam txhab lag luam hauv tuam txhab txawv teb chaws thiab txawv teb chaws, thiab tau mus txog qhov hluav taws xob hluav taws xob ntawm< 30v="" (raws="" li="" pom="" hauv="" daim="" duab="">
Nrog kev tshwm sim ntawm cov ntaub ntawv thoob ntiaj teb, cov khoom siv hluav taws xob yuav zoo dua, ntseeg tau thiab ua lag luam me, thiab cov tseev kom muaj rau kev tsim hluav taws xob cov khoom siv yuav nruj dua. Peb txaus siab ua haujlwm ua ke nrog feem ntau ntawm cov kws tshawb fawb thiab cov thev naus laus zis hauv kev lag luam hluav taws xob tau muab kev ua si tag nrho rau peb tus kheej los tiv thaiv kev ua lag luam tiv thaiv kev lag luam thev naus laus zis zoo. Cov ntsiab lus, txhim kho teeb meem, kov yeej cov teeb meem kev lag luam hauv kev lag luam, ua txoj haujlwm zoo ntawm kev pabcuam, thiab ua tau raws li cov kev sib tw tshiab coj los ntawm cov khoom lag luam zoo, cov khoom lag luam zoo!
