Aluminium alloy tiv thaiv laminate ua si lub luag haujlwm hauv kev sib khi thiab txhawb nqa. Lub thawv hlaus tiv thaiv tag nrho cov tshuab hluav taws xob tsim thiab ua tam sim no hloov chaw nres tsheb. Yog tias cov khoom siv tiv thaiv luv luv, lub vaj huam sib luag hnub ci lub thawv txig txiav tawm lub luv luv ntawm txoj hlua roj teeb kom tiv thaiv tag nrho cov kab hluav taws. Qhov tseem ceeb tshaj plaws hauv lub thawv hlws ris yog xaiv ntawm diodes. Ua raws li hom xov tooj ntawm tes hauv lub rooj sib txoos, hnub ci vaj huam sib luag qhov sib luag diodes kuj tseem muaj qhov sib txawv. Silicone sealing muaj nuj nqi yog siv los khi qhov kev sib txuas ntawm cov khoom tiv thaiv thiab cov txhuas txhuas thav duab, hnub ci vaj huam sib luag thiab cov tivthaiv thiab cov thawv txuas. Qee lub tuam txhab siv ob npaug xov ntawm ob kab xev thiab ua npuas dej es tsis txhob siv cov tshuaj silica. Silicone yog siv dav hauv Suav teb. Cov txheej txheem yog yooj yim, yooj yim, yooj yim rau kev khiav lag luam, hnub ci vaj huam sib luag thiab tus nqi qis heev.
Tam sim no, cov ntaub ntawv siv cov khoom siv silicon (suav nrog polycrystalline silicon thiab monocrystalline silicon) yog cov ntaub ntawv tseem ceeb tshaj plaws, cov hnub ci vaj huam sib luag nrog cov lag luam feem ntau tshaj 90%, hnub ci vaj huam sib luag thiab yuav nyob twj ywm cov ntaub ntawv tseem ceeb rau lub hnub ci lub hlwb rau lub sijhawm ntev. yav tom ntej. Kev lag luam thev naus laus zis cov khoom siv polysilicon tau ntev dhau los ua haujlwm ntawm 10 lub tuam txhab hauv 7 lub tuam txhab hauv 3 lub teb chaws, suav nrog Tebchaws Asmeskas, Nyij Pooj, Hnub ci vaj huam sib luag thiab lub teb chaws Yelemees, ua rau kev thev naus laus zis thiab kev lag luam monopoly.
