Qhov ua rau ntawm LED teeb hlaws vuam txheej txheem tuag teeb

Thaum lub sij hawm tsim khoom, qee lub teeb hlaws tau ntsib nyob rau hauv qhov tshwm sim uas muaj qhov tshwm sim ntawm ib qho, ib txoj hlua, thiab ob peb txoj hlua ntawm lub teeb hlaws thaum kuaj. Txoj kev vuam tuaj yeem muab faib ua hluav taws xob hlau vuam, cua sov platform vuam thiab reflux vuam, thiab lwm yam .: A, feem ntau siv hluav taws xob hlau vuam, xws li kuaj thiab tu. Vim tias feem ntau cov tuam txhab lag luam uas twb muaj lawm yog rau kev txuag nqi, feem ntau ntawm cov tub rog yuav khoom hluav taws xob yog feem ntau. Cov khoom tsis tsim nyog yog feem ntau tsis zoo hauv av, thiab muaj cov xau. Qhov no yog sib npaug los ua ib lub voj uas tsim los ntawm cov xau hlau taub hau-welding LED-tib neeg lub cev-lub ntiaj teb, uas txhais tau hais tias kaum ob lub sij hawm- Pua pua ntawm lub sij hawm lub voltage uas lub teeb beaded tau ntxiv rau lub LED teeb hlaws, thiab nws instantly. hlawv nws tawm. Lus Cim: Qhov xwm txheej ntawm cov hluav taws xob zoo li qub yuav hnyav dua, vim tias thaum tib neeg lub cev txuas nrog txoj siv hluav taws xob, qhov kev tiv thaiv hauv av me dua, thiab tam sim no los ntawm tib neeg lub cev mus rau lub teeb hlaws yuav loj dua. Tseem muaj ntau lub teeb hlaws dai teeb meem. B, lub teeb tuag tshwm sim los ntawm lub tshav kub platform welded. Vim yog daim ntawv teev npe teeb pom kev tas mus li, feem ntau cov tuam txhab lag luam kom ua tau raws li cov kev xav tau ntawm cov khoom me me thiab cov npe coj mus kuaj, vim yog cov khoom siv qis, cov qauv yooj yim thiab kev ua haujlwm, lub tshuab cua sov tau dhau los ua cov cuab yeej tsim khoom zoo tshaj plaws, txawm li cas los xij, vim yog cov qauv tsim thiab kev ua haujlwm yooj yim siv ib puag ncig (piv txwv li: muaj qhov teeb meem uas qhov kub thiab txias hauv qhov chaw nrog lub kiv cua) thiab cov qib kev coj ua thiab kev tswj xyuas cov neeg ua haujlwm vuam thiab kev tswj cov vuam ceev tau dhau los ua qhov teeb meem loj ntawm cov teeb tuag. Tsis tas li ntawd, cov khoom siv cua sov Platform grounding teeb meem. C, reflux welding, feem ntau txoj kev vuam no yog txoj kev txhim khu kev qha tshaj plaws, tsim nyog rau ntau qhov ntau lawm thiab ua haujlwm. Yog tias kev ua haujlwm tsis raug, nws yuav ua rau muaj teeb meem loj heev, xws li kev hloov pauv tsis tsim nyog, lub tshuab tsis zoo hauv av, thiab lwm yam. 2. Kev cia khoom tsis raug ua rau lub teeb tuag: qhov teeb meem zoo li no feem ntau tshwm sim. Txij li qhov teeb meem ntawm kev tiv thaiv cov dej noo-pov thawj tom qab lub pob qhib, lub foob ntawm lub teeb hlaws feem ntau siv cov khoom siv silicone. Raws li qee qhov dej nqus cov yam ntxwv, lub teeb hlaws muab tshuaj txhuam tom qab cov dej noo tau tshaj tawm los ntawm cov hlaws noo noo. Tom qab lub rooj tsavxwm, cov silicone ntawm cov silicone tom qab qhov kub-kub vuam txheej txheem yuav kub thiab cog lus. Cov xov kub, nti, thiab brackets yuav deformed thiab cov xov kub yuav tawg. Lub teeb pom kev zoo yuav raug tsim tawm. Nyob rau hauv ib puag ncig, qhov chaw cia kub yog -40 C-100 C, thiab cov txheeb ze av noo qis dua 85%; nws yog qhov zoo dua los siv LED hauv 3 lub hlis raws li nws cov khoom ntim khoom qub kom tsis txhob xeb ntawm lub bracket; Thaum lub hnab ntim LED qhib, lub hnab ntim tau qhib. Tom qab ntawd, siv nws sai li sai tau. Lub sijhawm no, qhov ntsuas kub yog 5-30, thiab cov av noo nyob hauv qab 60%. 3. Kev tu tshuaj lom neeg: Tsis txhob siv cov kua tshuaj tsis paub los ntxuav lub LED, vim tias qhov ntawd yuav ua rau lub ntsej muag ntawm LED colloid puas tsuaj thiab txawm ua rau collagen tawg. Yog tias tsim nyog, thov siv cawv-paj rwb swabs hauv chav tsev kub thiab qhov cua. Lub sij hawm tswj tau zoo tshaj plaws nyob rau hauv ib qho cua daj cua dub tiav. 4, deformation ua rau lub teeb tuag: Vim lub deformation ntawm qee lub teeb phaj, tus neeg teb xov tooj yuav yog yas. Vim lub deformation ntawm lub rooj tsavxwm, lub teeb hlaws dai ntawm nws kuj yuav deform tib lub sijhawm. Muaj lub rooj tsavxwm no rau kev phais yas ua ntej ntau lawm. Lub sijhawm ntev kev tsim khoom sib dhos thiab kev txav mus los kuj tuaj yeem ua rau qhov tshwm sim. Kuj tseem muaj kev sib tsoo. Txhawm rau ua kom yooj yim ntawm cov txheej txheem ntau lawm, lub teeb board yog stacked ntawm lub siab nyiam. Vim lub ntiajteb txawj nqus, lub teeb hlaws qis yuav raug hloov mus rau cov xov golden. 5. Cov qauv hluav taws xob hluav taws xob, cov khoom siv hluav taws xob thiab lub teeb pom kev tsis sib haum: Vim lub zog tsis tsim nyog tsim los yog xaiv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ntau tshaj qhov txwv (ultra-tam sim no, cuam tshuam tam sim no); Thaum ntxov lub teeb poob 6, Hoobkas grounding: yuav tsum xyuas seb tag nrho cov kab hauv av ntawm lub Hoobkas puas zoo. 7, hluav taws xob zoo li qub: hluav taws xob zoo li qub tuaj yeem ua rau LED tsis ua haujlwm. Nws raug nquahu kom tiv thaiv ESD los ntawm kev puas tsuaj LED. A, LED nrhiav pom thiab sib dhos yuav tsum nqa cov hnab looj tes tiv thaiv zoo li qub thiab cov hnab looj tes tiv thaiv zoo li qub. B. Cov cuab yeej siv vuam thiab cov khoom siv ntsuas, cov rooj ua haujlwm, cov khoom cia, thiab lwm yam. yuav tsum muaj av zoo. C. Siv ion kiv cua kom tshem tawm cov hluav taws xob zoo li qub uas tsim los ntawm kev sib txhuam thaum khaws cia thiab sib dhos thaum khaws cia thiab sib dhos. D. Lub thawv khoom siv nrog LED siv cov khoom siv los tiv thaiv zoo li qub, thiab lub hnab ntim khoom siv lub hnab hluav taws xob zoo li qub. E. Tsis txhob muaj fluke, kov lub LED. Qhov tshwm sim txawv txav uas yuav tshwm sim los ntawm LED puas los ntawm ESD yog: A. Inverse to, lub teeb yuav ua rau brightness. B. Tus nqi voltage yuav tsawg dua. LED tsis tuaj yeem ci thaum cov tsav tsheb qis tam sim no. 8. Kev vuam tsis zoo ua rau lub teeb tsis pom kev.
