Kev tsim cov txheej txheem ntawm LED teeb hlaws

Cov txheej txheem ntau lawm ntawmLED teeb hlaws daiyog qhov txuas tseem ceeb hauv kev lag luam teeb pom kev zoo LED. LED lub teeb hlaws, tseem hu ua lub teeb emitting diodes, yog cov khoom siv tseem ceeb siv ntau yam kev siv xws li teeb pom kev hauv tsev mus rau tsheb thiab kev lag luam teeb pom kev zoo. Nyob rau hauv xyoo tas los no, vim qhov zoo ntawm kev txuag hluav taws xob, lub neej ntev, thiab kev tiv thaiv ib puag ncig ntawm LED teeb hlaws, lawv qhov kev thov tau nce ntxiv, ua rau kev nce qib thiab kev txhim kho ntawm cov tshuab tsim khoom.

Cov txheej txheem tsim khoom ntawm LED teeb hlaws hlaws suav nrog ntau theem, los ntawm kev tsim cov khoom siv hluav taws xob mus rau qhov kawg sib dhos ntawm LED chips. Cov txheej txheem pib nrog kev xaiv cov khoom siv siab huv xws li gallium, arsenic, thiab phosphorus. Cov ntaub ntawv no tau muab sib xyaw ua ke hauv qhov sib luag kom tsim cov khoom siv hluav taws xob semiconductor uas tsim lub hauv paus ntawm LED thev naus laus zis.

Tom qab cov khoom siv semiconductor tau npaj, nws dhau los ntawm kev ua kom huv huv kom huv si kom tshem tawm cov impurities thiab txhim kho nws cov kev ua tau zoo. Cov txheej txheem purification no ua kom ntseeg tau tias LED teeb hlaws hlaws muab ntau dua ci ntsa iab, xim sib xws, thiab ua haujlwm tau zoo thaum siv. Tom qab purification, cov khoom yog txiav mus rau hauv me me wafers siv ib tug advanced cutter.

Cov kauj ruam tom ntej hauv cov txheej txheem tsim khoom suav nrog kev tsim cov chips LED lawv tus kheej. Cov wafers tau ua tib zoo kho nrog cov tshuaj tshwj xeeb thiab dhau los ua cov txheej txheem hu ua epitaxy, uas cov txheej txheem ntawm cov khoom siv semiconductor tau tso rau saum npoo ntawm wafer. Qhov kev tso tawm no yog ua nyob rau hauv ib puag ncig tswj siv cov tswv yim xws li hlau-organic chemical vapor deposition (MOCVD) lossis molecular beam epitaxy (MBE).

Tom qab cov txheej txheem epitaxial ua tiav, lub wafer yuav tsum tau mus dhau ntawm cov txheej txheem ntawm photolithography thiab etching cov kauj ruam los txhais cov qauv ntawm LED. Cov txheej txheem no koom nrog kev siv cov txheej txheem photolithography siab heev los tsim cov qauv nyuaj rau ntawm qhov chaw ntawm lub wafer uas txhais tau ntau yam ntawm LED nti, xws li p-hom thiab n-hom cheeb tsam, active txheej, thiab cov ntaub ntawv tiv tauj.

Tom qab LED chips raug tsim, lawv mus los ntawm kev txheeb xyuas thiab ntsuas cov txheej txheem kom ntseeg tau tias lawv qhov zoo thiab kev ua tau zoo. Lub nti yog kuaj rau cov yam ntxwv hluav taws xob, ci ntsa iab, xim kub, thiab lwm yam kev ntsuas kom ua tau raws li cov qauv xav tau. Cov chips tsis raug raug txheeb xyuas thaum ua haujlwm chips mus rau theem tom ntej.

Nyob rau theem kawg ntawm kev tsim khoom, LED chips tau ntim rau hauv qhov kawg LED teeb hlaws. Cov txheej txheem ntim khoom suav nrog kev txhim kho cov chips rau hauv cov kab hlau lead, txuas rau cov hluav taws xob tiv tauj, thiab ntim lawv rau hauv cov khoom siv tiv thaiv. Cov ntim no tiv thaiv cov nti los ntawm ib puag ncig cov ntsiab lus thiab ua rau nws cov kav ntev.

Tom qab ntim khoom, LED teeb hlaws hlaws yog raug rau kev ua haujlwm ntxiv, ua haujlwm ntev, thiab kev ntseeg siab. Cov kev sim no simulate cov kev ua haujlwm tiag tiag los xyuas kom meej tias LED teeb hlaws ua haujlwm ruaj khov thiab tuaj yeem tiv taus ntau yam ib puag ncig xws li kub hloov pauv, av noo, thiab kev co.

Zuag qhia tag nrho, cov txheej txheem ntawm LED teeb hlaws hlaws yog qhov nyuaj heev, xav tau cov tshuab siab heev, kev tswj xyuas meej, thiab kev tshuaj xyuas nruj. Kev nce qib hauv LED thev naus laus zis thiab kev ua kom zoo ntawm cov txheej txheem ntau lawm tau pab ua kom cov teeb pom kev zoo LED muaj zog dua, ruaj khov, thiab txhim khu kev qha. Nrog rau kev tshawb fawb thiab kev loj hlob tsis tu ncua hauv daim teb no, cov txheej txheem tsim khoom yuav tsum tau txhim kho ntxiv, thiab LED cov hlaws teeb yuav ua tau zoo dua thiab pheej yig dua yav tom ntej.

Yog tias koj txaus siab rau cov txheej txheem ntawm LED teeb hlaws, txais tos hu rau LED txoj kev teeb chaw tsim tshuaj paus TIANXIANG raunyeem ntxiv.
