Guangmai Technology yog cov kws tshaj lij hauv kev ua XHP50 LED sib npaug 5050 SMD LED ALN puag.
Dab tsi yog Eutectic Die Bonding / Eutectic welding rau LED chips ???
Au-Sn eutectic (AuSn20), tseem hu ua kub-tin alloy, tso cov kub thiab stannous ions nyob rau hauv cov tshuaj plating rau ntawm txoj hauj lwm teev nyob rau hauv qhov kev txiav txim raws li qhov loj feem ntawm Au80 feem pua thiab cov ntsiab lus ntawm tin 20 feem pua los ntawm electrolysis. . Au-Sn eutectic muaj ob theem ntawm AuSn (δ) thiab Au5Sn (ζ) low-temperature eutectic precious hlau solder. Nws cov tuab yog tswj los ntawm lub sij hawm tso nyiaj thiab tuaj yeem ncaj qha mus rau txheej kub ntawm 300 degree yam tsis muaj flux.
Nruab nrab brazing kub
Lub brazing kub tsuas yog 20-30 degree siab tshaj nws melting point (uas yog, hais txog 300-310). Thaum lub sij hawm brazing txheej txheem, raws li eutectic muaj pes tsawg leeg ntawm cov alloy, ib tug me me degree ntawm superheat yuav yaj thiab infiltrate lub alloy; Tsis tas li ntawd, cov txheej txheem solidification ntawm cov hlau ua tau sai heev. Yog li ntawd, kev siv cov kub-tin alloy tuaj yeem txo lub voj voog ntawm tag nrho cov txheej txheem brazing. Lub brazing kub ntau ntawm kub-tin alloy yog haum rau kev sib dhos ntawm cov khoom uas yuav tsum tau muaj kev ruaj ntseg siab. Nyob rau tib lub sijhawm, cov khoom no tuaj yeem tiv thaiv kev sib dhos tom qab siv cov hlau lead-dawb solder ntawm qhov kub thiab txias. Kev sib dhos kub ntawm cov solders yog kwv yees li 260 degree.
Siab zog
Lub zog tawm los ntawm kub-tin alloy yog siab heev. Txawm tias qhov kub ntawm 250 txog 260 degree, nws lub zog tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm huab cua nruj.
Tsis xav tau flux
Kub tuav ib tug loj feem (80 feem pua) nyob rau hauv lub alloy muaj pes tsawg leeg, thiab cov degree ntawm oxidation ntawm cov khoom yog tsawg. Yog tias lub tshuab nqus tsev lossis sib xyaw ua ke ntawm kev txo cov pa roj xws li nitrogen thiab hydrogen siv rau hauv cov txheej txheem brazing, tshuaj flux tsis tsim nyog.
Tsawg viscosity
Cov kua kub-tin alloy muaj viscosity tsawg heev, uas tuaj yeem ua rau qee qhov khoob loj.
Zoo wettability
Nws muaj qhov zoo corrosion tshwm sim ntawm cov hlau lead-dawb tin solder ntawm txheej kub-plated,
Cov muaj pes tsawg leeg ntawm cov kub-tin alloy thiab cov kub-plated txheej yog nyob ze, yog li cov degree ntawm leaching ntawm ib tug nyias plating txheej los ntawm diffusion yog tsawg heev, thiab tsis muaj kev tsiv teb tsaws tshwm sim zoo li nyiaj.
Tsis tas li ntawd, Au80 feem pua Sn20 feem pua hluav taws xob kuj muaj kev tiv thaiv corrosion siab, siab creep tsis kam, thiab zoo thermal thiab hluav taws xob conductivity.

Ua tib neeg nyiam cov khoom siv teeb pom kev zoo. Tam sim no, cov khoom siv LED tau siv dav hauv cov khw muag khoom, khw muag khoom, chaw ua haujlwm, tsev kho mob, subways, factories, squares, parks, txoj kev, mobile teeb pom kev zoo thiab lwm yam. Lub tuam txhab ua raws li txoj cai kev lag luam ntawm "kev tsim kho tshiab raws li kev tsav tsheb, kev ua lag luam raws li kev taw qhia, thiab kev pabcuam raws li qhov chaw". Cov khoom siv dav siv los ntawm ntau cov neeg siv khoom hauv tsev. Nyob rau tib lub sijhawm, lawv kuj raug muag rau Tebchaws Europe, Amelikas, Southeast Asia thiab lwm lub tebchaws, thiab tau txais txiaj ntsig zoo thiab pom zoo.
