Yuav ua li cas txheeb xyuas seb SMD LED CHIP yog cov hlau dawb huv
Cov hlau kub siv rau ntim cov teeb ci LED hlaws muaj cov ntsiab lus kub ntau dua 99.99%. Cov kub ntawm cov khoom no yog tsim los ntawm cov txheej txheem kos duab hlau. Ntxiv rau 99.99% kub, cov kub no tseem muaj 1% lossis tsawg dua ntawm lwm cov ntsiab lus. kab kawm. Ib qho ntawm cov khoom tseem ceeb ntawm LED teeb hlaws pob yog cov hlau kub. Cov hlau kub yog tus choj txuas lub teeb-emitting nti thiab cov khoom sib koom ua ke, uas ua lub luag haujlwm tseem ceeb hauv kev pab cuam lub neej ntawm LED teeb hlaws. Yog li yuav ua li cas txheeb xyuas qhov purity ntawm cov hlau kub?
Kev txheeb xyuas ntawm LED kub hlau tuaj yeem siv ICP purity detection method, mechanical property detection method, and EDS tivthaiv nrhiav kom tau txoj kev txiav txim siab purity ntawm LED kub hlau
Cov qib kub hlau purity tuaj yeem txheeb xyuas tau siv ICP purity kuaj los txiav txim siab ntxiv cov ntsiab lus alloying.
1. Saib ntawm cov tsos ntawm cov hlau kub ntawm LED teeb hlaws, ua ntej ntawm tag nrho cov, yuav tsum tsis muaj nicks, pits, khawb, tawg, pob, nyiaj cheb thiab lwm yam tsis xws luag uas txo cov kev pab cuam lub neej ntawm lub ntaus ntawv ntau tshaj 5%. ntawm cov hlau txoj kab uas hla ntawm qhov chaw ntawm cov hlau kub. Thaum lub sij hawm kev kos duab ntawm cov hlau kub, qhov tsis xws luag ntawm qhov chaw ntawm cov hlau yuav ua rau muaj kev nce hauv qhov ntom ntom tam sim no, ua rau cov khoom puas yooj yim rau hlawv, thiab tib lub sij hawm, muaj peev xwm tiv taus cov neeg kho tshuab kev nyuaj siab. txo qis, ua rau cov hlau lead sab hauv tawg ntawm qhov puas. Qhov thib ob, qhov saum npoo ntawm cov hlau kub yuav tsum tsis muaj roj, xeb, plua plav thiab lwm yam adhesions, 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.
2. Muaj qhov sib txawv ntawm txoj kab uas hla ntawm cov hlau tshwj xeeb rau LED teeb hlaws thiab cov hlau tsis tsim nyog. 1 gram kub tuaj yeem kos cov hlau kub nrog qhov ntev ntawm 26.37m thiab txoj kab uas hla ntawm 50μm (2 mil), lossis qhov ntev ntawm 105.49m. , ib tug kub hlau nrog ib txoj kab uas hla ntawm 25 μm (1 mil). 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 ntsuas tsis kam ntawm cov hlau kub yuav raug ntaus yog ib feem peb ntawm cov nqi ib txwm muaj. Rau cov neeg muag khoom kub, qhov nyias nyias ntawm txoj kab uas hla ntawm cov hlau kub, tus nqi qis dua, thiab cov nyiaj tau los ntau dua thaum cov nqi muag khoom tseem zoo li qub.
Rau LED teeb hlaws cov neeg siv khoom uas siv cov xov hlau kub, kev yuav cov xov hlau kub uas txiav cov fab hauv txoj kab uas hla yuav muaj kev pheej hmoo ntawm kev ua kom tsis muaj zog ntawm cov hlau kub thiab txo cov fusing tam sim no, uas yuav txo tau lub neej ntawm LED teeb hlaws teeb pom kev zoo. Lub neej ntawm 1.0mil kub xaim yuav tsum luv dua li ntawm 1.2mil kub hlau, tab sis kev tshuaj xyuas yooj yim ntawm lub Hoobkas ntim tsis tuaj yeem kuaj, thiab txoj kab uas hla ntawm cov hlau kub tsuas yog kuaj tau nrog cov cuab yeej precision.
3. Qhov tshwj xeeb kub hlau rau LED teeb hlaws yog kos los ntawm cov khoom siv nrog kub purity ntau tshaj 99.99%. Los ntawm kev tsim cov hlau alloy tsim nyog, cov hlau kub muaj lub zog tensile siab txaus thiab kev sib khi lub zog, zoo sphericity, thiab kev vibration puas. qis kom zoo dua. Feem ntau ntawm cov xov hlau sib txuas yuav tsum yog high-purity alloy hlau uas muaj purity ntau tshaj 99.99%, thiab tag nrho cov nyiaj ntawm cov kab kawm (xws li Ag / Cu / Si / Ca / Mg) yuav tsum tau khaws cia hauv qab 0.01 kom tswj tau cov yam ntxwv. ntawm kub.
Siv cov cuab yeej ntsuas khoom, uas yog, ntsuas qhov tawg thiab elongation ntawm cov hlau kub
Ib qho zoo kub hlau uas tuaj yeem tiv taus qhov poob siab ntawm resin encapsulation yuav tsum muaj cov khoom tawg thiab elongation. Nyob rau tib lub sijhawm, lub zog tawg thiab elongation ntawm cov hlau kub ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo ntawm cov hlau sib txuas, thiab cov hlau txuas nrog kev sib tsoo siab thiab elongation yog qhov tsim nyog rau kev sib txuas.
Cov hlau muag kub dhau yuav ua rau: ① lub koov hlau sags; ② cov duab kheej kheej tsis ruaj khov; ③ lub pob caj dab yog yooj yim kom ntsws; ④ cov hlau kub yog qhov yooj yim tawg.
Cov hlau kub hnyav dhau yuav ua rau: ① nti electrode lossis epitaxy yog xuas nrig tawm ntawm lub qhov; ② lub caj dab ntawm lub pob kub tawg; ③ Nws yog ib qho nyuaj rau kev tsim cov hlau; ④ Nws yog ib qho nyuaj rau tswj lub arc ntawm koov hlau.
Siv tshuaj muaj pes tsawg leeg kuaj - EDS muaj pes tsawg leeg xeem txoj kev
Txheeb xyuas cov khoom xa 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 zoo, thermal conductivity, corrosion kuj, zoo toughness, thiab zoo heev tshuaj stability, tab sis tus nqi ntawm cov hlau kub yog kim heev thiab cov nqi ntim kuj siab dhau lawm.
