Tam sim no, kev lag luam zeem muag ntawm kev lag luam coj zaub tau mus txog qhov siab tsis tau pom dua, thiab tus nqi tau ruaj khov, thiab nws kuj tau txais txiaj ntsig zoo los ntawm kev ua lag luam. Kuv ntseeg tias yav tom ntej yuav muaj ntau qhov chaw siv cov khoom coj ua, suav nrog hauv tsev! Ntau tus neeg siv khoom tsis muaj kev paub txog LED cov lus qhia thiab tsuas yog saib ntawm tus nqi, thiab lawv tsis paub yuav ua li cas kom paub qhov txawv ntawm cov hlau kub thiab hlau alloy rau LED zaub. Qhov tseeb, muaj ntau yam khoom siv rau LED teeb hlaws dai, suav nrog tooj liab brackets, kub hlau ntim, thiab tooj liab brackets. Alloy hlau encapsulation, tooj liab stent tooj liab hlau encapsulation, thiab hlau stent encapsulation ntawm cov khoom ob peb xyoos dhau los. Tam sim no, hlau stents tau raug tshem tawm, thiab tsuas yog qee qhov ntawm lawv yuav raug siv! Cov khoom ntim sib txawv kuj txiav txim siab txog lub neej kev pabcuam, xim, ci, thiab cov txiaj ntsig ntawm LED cov hlaws dai, yog li nws yog ib qho tsim nyog yuav tsum nkag siab txog cov txheej txheem ntawm cov khoom siv ntawm LED zaub kub xaim pob ua ntej xaiv LED zaub. .

Cov txheej txheem kev txheeb xyuas ntawm LED zaub kub xaim ntim khoom yog raws li hauv qab no
Txoj Kev 1: Kev tshuaj xyuas tshuaj muaj pes tsawg leeg
1. EDS muaj pes tsawg leeg tshawb pom: kev txheeb xyuas cov khoom siv tuaj: kub hlau, nyiaj hlau, kub-clad nyiaj alloy hlau, tooj liab hlau, txhuas hlau.
Kub hlau muaj qhov zoo ntawm cov hluav taws xob hluav taws xob zoo, zoo thermal conductivity, corrosion kuj, zoo toughness, thiab zoo heev tshuaj stability. Txawm li cas los xij, tus nqi ntawm cov hlau kub yog kim, uas ua rau cov nqi ntim siab. Nyob rau hauv lub sij hawm lub sij hawm, plaub hlau ntsiab ntawm kub, nyiaj, tooj liab thiab txhuas nyob rau hauv cov kev hloov ntawm pab pawg neeg ntawm hlau ntsiab muaj hluav taws xob conductivity. Ntau lub tuam txhab LED sim tsim cov ntaub ntawv xws li tooj liab alloy, kub-clad silver alloy hlau, thiab nyiaj alloy hlau los hloov cov hlau kub kim. Txawm hais tias cov kev xaiv no zoo dua rau cov xov hlau kub hauv qee cov khoom, lawv muaj qhov phem dua ntawm cov tshuaj lom neeg ruaj khov. Piv txwv li, cov xov hlau nyiaj thiab kub-coated silver alloy xov hlau yog raug rau sulfur / chlorine / bromination corrosion, thiab tooj liab xov hlau yog oxidation. Nyob rau hauv cov ntaub ntawv ntawm encapsulated silica gel zoo ib yam li cov dej-absorbent thiab breathable sponge, cov kev xaiv no ua rau cov hlau nplaum uas raug rau cov tshuaj corrosion, txo qhov kev ntseeg ntawm lub teeb qhov chaw, thiab siv tau ntev, thiab LED teeb hlaws dai yooj yim. tawg thiab tuag.
2. ICP purity test: txheeb xyuas qhov purity theem ntawm cov hlau kub thiab txiav txim siab ntxiv cov ntsiab lus alloy.
LED daim ntawv cog lus hlau yog kos los ntawm cov khoom siv nrog kub purity ntawm 99.99 feem pua lossis ntau dua, uas muaj cov kab mob xws li Ag / Cu / Si / Ca / Mg. Los ntawm kev tsim cov hlau alloy tsim nyog, cov hlau kub muaj qhov zoo ntawm qhov muaj zog tensile siab thiab kev sib txuas ntawm lub zog, kev tsim pob zoo, thiab qis kev vibration puas. Feem ntau ntawm daim ntawv cog lus alloy hlau yuav tsum yog high-purity alloy hlau nrog ib tug purity ntawm 99.99 feem pua los yog ntau tshaj, thiab tag nrho cov nyiaj ntawm kab kawm yuav tsum tau khaws cia hauv qab no 0.01 feem pua kom tswj cov yam ntxwv ntawm kub.
Txoj Kev 2: Diameter deviation
Ib gram ntawm kub tuaj yeem kos ib lub xov tooj kub nrog qhov ntev ntawm 26.37m thiab txoj kab uas hla ntawm 50μm (2 mil), lossis ib lub xov tooj kub nrog qhov ntev ntawm 105.49m thiab txoj kab uas hla ntawm 25μm (1 mil) . Yog tias qhov ntev ntawm cov hlau kub yog tsau, yog tias txoj kab uas hla ntawm cov xaim kub tuaj yog ib nrab ntawm qhov qub, ces qhov kev tiv thaiv ntsuas ntawm cov hlau kub yog ib feem plaub ntawm qhov qub. Rau cov neeg muag khoom, qhov me me ntawm txoj kab uas hla ntawm cov hlau kub, tus nqi qis dua, thiab cov nyiaj tau los ntau dua thaum tus nqi tseem tsis hloov. Rau cov neeg siv khoom siv LED uas siv cov xov hlau kub, kev yuav cov xov hlau kub uas txiav cov ces kaum ntawm txoj kab uas hla yuav ua rau muaj kev tiv thaiv ntawm cov xov hlau kub thiab txo qhov kev pheej hmoo ntawm fuse tam sim no, uas yuav txo tau lub neej ntawm LED teeb pom kev zoo. Lub neej ntawm 1.0 mil kub hlau yuav tsum luv dua li ntawm 1.2 mil kub hlau.

Txoj Kev 3: Kev tshuaj xyuas qhov zoo
(1) Qhov saum npoo ntawm cov hlau yuav tsum tsis pub muaj nicks, pits, khawb, tawg, pob, txo qis thiab lwm yam tsis xws luag uas txo cov kev pab cuam lub neej ntawm cov cuab yeej uas ntau tshaj 5 feem pua ntawm txoj kab uas hla. Thaum lub sij hawm kev kos duab ntawm cov hlau kub, qhov chaw tsis xws luag ntawm cov hlau nto yuav ua rau kom qhov ntom ntom tam sim no thiab ua rau cov khoom puas tau yooj yim hlawv. Nyob rau tib lub sijhawm, qhov kev tiv thaiv rau cov neeg kho tshuab kev nyuaj siab yog txo thiab qhov puas ntawm cov hlau lead hauv sab hauv yog tawg.
(2) Qhov saum npoo ntawm cov hlau kub yuav tsum tsis muaj roj, xeb, plua plav, thiab lwm yam adherents, uas yuav txo tau lub zog sib txuas ntawm cov hlau kub thiab LED nti, thiab nruab nrab ntawm cov hlau kub thiab lub bracket.
Txoj Kev 4: Kev ntsuas cov khoom siv tshuab
(Lub pob tawg thiab elongation ntawm cov hlau zoo kub uas tuaj yeem tiv taus qhov cuam tshuam los ntawm cov pob resin yuav tsum muaj cov txheej txheem tawg thiab elongation. Nyob rau tib lub sijhawm, kev tawg quab yuam thiab elongation ntawm cov hlau kub ua lub luag haujlwm tseem ceeb hauv kev sib tsoo. Qhov zoo ntawm cov hlau daim ntawv cog lus, Bonding hlau nrog high breaking tus nqi thiab elongation tus nqi yog ntau conducive rau bonding, mos kub hlau yuav ua rau cov nram qab no tsis zoo: (1) Arch hlau sagging; (2) spherical instability; (3) Pob caj dab yog yooj yim rau shrink (4) Kub hlau yog ib qho yooj yim tawg, kub kub hlau yuav ua rau cov nram qab no tsis xws luag: (1) Lub qhov yog punched tawm ntawm nti electrodes los yog epitaxy; (2) Lub caj dab ntawm lub pob kub yog tawg; (3) ) Nws yog ib qho nyuaj rau kev tsim alloys; (4) Nws yog ib qho nyuaj rau tswj lub koov hlau arc.
Kuv ntseeg hais tias nrog cov kev paub saum toj no, txhua tus tuaj yeem txheeb xyuas qhov tseeb ntawm cov pob hlau kub ntawm LED zaub. Nws yog ib nqi sau cia hais tias txawm hais tias cov kub hlau, hlau alloy, thiab tooj liab hlau tsuas yog ib lo lus sib txawv, tus nqi thiab kev siv cov nyhuv muaj qhov sib txawv loj heev. Thaum xaiv cov khoom, tsis txhob las mees cov ntsiab lus tseem ceeb vim hais tias koj greedy rau pheej yig! Muab cov hlau kub thiab tooj liab los sib piv cov nyhuv tso saib, muaj qhov sib txawv loj ntawm cov duab pom
