Lumispot Tech ntiav cov txheej txheem ntim khoom uas siv AnSn solder es tsis txhob siv cov tshuaj indium solder los daws cov teeb meem ntsig txog thermal qaug zog, electromigration, thiab hluav taws xob-kub tsiv teb tsaws los ntawm indium solder. Los ntawm kev siv AuSn solder, peb lub tuam txhab aims los txhim kho cov khoom lag luam kev ntseeg siab thiab kev ua haujlwm ntev. Qhov kev hloov pauv no tau ua tiav thaum ua kom muaj qhov sib npaug ntawm qhov sib npaug ntawm qhov bar, ntxiv rau kev txhim kho cov khoom lag luam kev ntseeg siab thiab lub neej ntev.
Nyob rau hauv lub ntim tshuab ntawm high-power semiconductor pumped solid-state laser, indium (In) hlau tau saws raws li cov khoom siv vuam los ntawm ntau thoob ntiaj teb manufacturers vim nws qhov zoo ntawm cov melting point, tsawg vuam kev nyuaj siab, yooj yim ua hauj lwm, thiab zoo yas. deformation thiab infiltration. Txawm li cas los xij, rau semiconductor pumped khoom lub xeev lasers nyob rau hauv daim ntawv thov kev ua haujlwm tas mus li, kev hloov pauv kev ntxhov siab yuav ua rau muaj kev ntxhov siab qaug zog ntawm indium vuam txheej, uas yuav ua rau cov khoom tsis ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv siab thiab qis kub thiab ntev mem tes dav, qhov tsis ua hauj lwm tus nqi ntawm indium vuam yog pom tseeb heev.
Kev sib piv ntawm kev ntsuas lub neej nrawm ntawm lasers nrog cov pob khoom sib txawv
Tom qab 600 teev ntawm kev laus, tag nrho cov khoom ntim nrog indium solder poob; thaum cov khoom ntim nrog kub tin ua haujlwm rau ntau tshaj 2,000 teev nrog yuav luag tsis muaj kev hloov pauv ntawm lub zog; xav txog qhov zoo ntawm AuSn encapsulation.
Txhawm rau txhim kho kev ntseeg siab ntawm lub zog hluav taws xob semiconductor lasers thaum tswj xyuas qhov sib xws ntawm ntau yam ntsuas kev ua tau zoo, Lumispot Tech txais Hard Solder (AuSn) ua hom tshiab ntawm cov khoom ntim. Kev siv cov coefficient ntawm thermal expansion matched substrate khoom (CTE-Matched Submount), qhov zoo tso tawm ntawm thermal stress, ib tug zoo kev daws teeb meem rau technical teeb meem uas tej zaum yuav ntsib nyob rau hauv kev npaj ntawm hard solder. Ib qho xwm txheej tsim nyog rau cov khoom siv substrate (submount) kom muaj peev xwm raug soldered rau semiconductor nti yog nto metallization. Surface metallization yog tsim los ntawm ib txheej ntawm diffusion barrier thiab solder infiltration txheej ntawm cov khoom siv substrate.

Txhawm rau txhim kho kev ntseeg siab ntawm lub zog hluav taws xob semiconductor lasers thaum tswj xyuas qhov sib xws ntawm ntau yam ntsuas kev ua tau zoo, Lumispot Tech txais Hard Solder (AuSn) ua hom tshiab ntawm cov khoom ntim. Kev siv cov coefficient ntawm thermal expansion matched substrate khoom (CTE-Matched Submount), qhov zoo tso tawm ntawm thermal stress, ib tug zoo kev daws teeb meem rau technical teeb meem uas tej zaum yuav ntsib nyob rau hauv kev npaj ntawm hard solder. Ib qho xwm txheej tsim nyog rau cov khoom siv substrate (submount) kom muaj peev xwm raug soldered rau semiconductor nti yog nto metallization. Surface metallization yog tsim los ntawm ib txheej ntawm diffusion barrier thiab solder infiltration txheej ntawm cov khoom siv substrate.
Nws lub hom phiaj yog nyob rau ntawm ib sab los thaiv cov solder rau cov khoom siv substrate diffusion, ntawm qhov tod tes, ntxiv dag zog rau cov solder nrog lub substrate khoom vuam muaj peev xwm, tiv thaiv cov txheej txheem ntawm cov kab noj hniav. Deg metallization tuaj yeem tiv thaiv cov khoom siv substrate nto oxidation thiab noo noo nkag, txo qhov kev tiv thaiv kev sib cuag hauv cov txheej txheem vuam, thiab yog li txhim kho vuam lub zog thiab cov khoom lag luam kev ntseeg tau. Kev siv cov khoom siv tawv tawv AuSn ua cov khoom siv vuam rau cov khoom siv hluav taws xob semiconductor pumped lub xeev lasers tuaj yeem tiv thaiv indium kev nyuaj siab qaug zog, oxidation thiab electro-thermal migration thiab lwm yam tsis xws luag, txhim kho kev ntseeg siab ntawm semiconductor lasers nrog rau kev pab cuam lub neej ntawm lub laser. Kev siv cov tshuab kub-tin encapsulation tuaj yeem kov yeej cov teeb meem ntawm electromigration thiab electrothermal migration ntawm indium solder.
Kev daws los ntawm Lumispot Tech
Nyob rau hauv tas li ntawd los yog mem tes lasers, lub tshav kub generated los ntawm kev nqus ntawm lub twj tso kua mis hluav taws xob los ntawm lub laser nruab nrab thiab sab nraud cua txias ntawm nruab nrab ua rau uneven kub tis nyob rau hauv lub laser nruab nrab, ua rau kub gradients, ua rau cov kev hloov nyob rau hauv lub refractive index ntawm nruab nrab. thiab tom qab ntawd ua ntau yam thermal teebmeem. Lub thermal deposition nyob rau hauv lub nce nruab nrab ua rau lub thermal lensing nyhuv thiab thermally induced birefringence nyhuv, uas ua rau tej yam poob nyob rau hauv lub laser system, cuam tshuam lub stability ntawm lub laser nyob rau hauv kab noj hniav thiab qhov zoo ntawm cov zis beam. Nyob rau hauv ib tug tsis tu ncua khiav laser system, thermal stress nyob rau hauv lub nce nruab nrab hloov raws li lub twj tso kua mis zog nce. Cov teebmeem thermal ntau hauv lub cev cuam tshuam rau tag nrho cov laser system kom tau txais cov kab teeb pom kev zoo thiab cov zis ntau dua, uas yog ib qho ntawm cov teeb meem uas yuav tsum tau daws. Yuav ua li cas kom zoo inhibit thiab txo cov thermal nyhuv ntawm cov muaju hauv cov txheej txheem ua haujlwm, cov kws tshawb fawb tau teeb meem rau lub sijhawm ntev, nws tau dhau los ua ib qho kev tshawb fawb hotspots tam sim no.
Nd: YAG laser nrog thermal lens kab noj hniav
Nyob rau hauv qhov project ntawm kev txhim kho high-power LD-pumped Nd:YAG lasers, lub Nd:YAG lasers nrog thermal lo ntsiab muag kab noj hniav tau daws, yog li ntawd lub module yuav tau txais lub hwj chim siab thaum tau txais high beam zoo.
Nyob rau hauv ib txoj haujlwm los tsim lub zog loj LD-pumped Nd:YAG laser, Lumispot Tech tau tsim G2-A module, uas zoo heev daws qhov teeb meem ntawm lub zog qis vim thermal lens-muaj kab noj hniav, tso cai rau lub module kom tau txais lub zog siab. nrog siab beam zoo.
