1. Chips
Cov muaj pes tsawg leeg ntawm wafer: nws yog tsim los ntawm kub ncoo, P ncej, N ncej, PN hlws ris, thiab rov qab kub txheej (dual ncoo wafer tsis muaj rov qab kub txheej). Lub wafer yog PN kev sib xyaw ua ke ntawm P-txheej semiconductor ntsiab lus thiab N-txheej semiconductor ntsiab rearranged thiab ua ke los ntawm electron zog. Nws yog qhov kev hloov pauv no uas ua rau lub wafer nyob rau hauv ib qho chaw ruaj khov.
Thaum muaj qee qhov hluav taws xob tau siv rau pem hauv ntej electrode ntawm wafer, lub qhov hauv thaj tsam P zoo yuav ua luam dej tsis tu ncua mus rau thaj tsam N, thiab cov hluav taws xob hauv cheeb tsam N yuav txav mus rau thaj tsam P thaj tsam ntawm lub qhov. Thaum cov electrons thiab qhov txav mus rau ib leeg, cov electrons thiab qhov sib txuas ua ke ua kom zoo siab photons thiab tsim lub teeb lub zog.
Kev faib tawm tseem ceeb, hom emitting nto: Feem ntau ntawm lub teeb yog tawm ntawm qhov chaw ntawm lub wafer. Tsib-sided luminous hom: Muaj ntau lub teeb emitting los ntawm qhov chaw thiab sab raws li luminous xim, liab, txiv kab ntxwv, daj, daj-ntsuab, ntshiab ntsuab, txheem ntsuab, xiav-ntsuab, xiav.
Qhov thib ob, lub bracket
Cov qauv ntawm lub bracket yog 1 txheej hlau, 2 txheej ntawm tooj liab plating (zoo conductivity, ceev cua sov dissipation), 3 txheej ntawm npib tsib xee plating (anti-oxidation), 4 txheej nyiaj plating (zoo xav, yooj yim rau hlau)
3. Silver kua nplaum (vim muaj ntau hom, peb coj H20E ua piv txwv)
Kuj tseem hu ua cov kua nplaum dawb, cov mis dawb, cov nplaum nplaum (ci kub: 100 degree / 1.5H) hmoov hmoov (conductivity, tshav kub dissipation, tsau wafer) ntxiv rau epoxy resin (kho nyiaj hmoov) ntxiv rau nyias (yooj yim rau do).
4. Kub hlau (coj φ1.0mil ua piv txwv)
Cov xov hlau kub siv hauv LEDs yog φ1.0mil, φ1.2mil, thiab cov khoom siv ntawm cov hlau kub. Cov khoom siv ntawm cov hlau kub siv rau LEDs feem ntau muaj 99.9 feem pua kub.
Siv cov yam ntxwv ntawm cov ntsiab lus kub siab, cov khoom muag muag, yooj yim deformation, zoo hluav taws xob conductivity thiab zoo cua sov dissipation, ib tug kaw Circuit Court yog tsim los ntawm cov nti thiab cov kev txhawb nqa.
5. Epoxy resin (coj EP400 ua piv txwv)
Muaj pes tsawg leeg: A thiab B ob pawg ntawm koob tshuaj.
A kua nplaum: Nws yog tus neeg sawv cev tseem ceeb, uas muaj epoxy resin ntxiv rau defoamer ntxiv rau cov neeg ua haujlwm kub-resistant ntxiv rau nyias.
Tus neeg sawv cev B: Nws yog tus neeg sawv cev kho, muaj cov kua qaub intoxication ntxiv rau pwm tso tawm tus neeg sawv cev ntxiv rau accelerator.
