Electrostatic puas yog dab tsi? Dab tsi ntawm LEDs raug cuam tshuam rau electrostatic puas thiab ua tsis tiav?
Cov hluav taws xob zoo li qub yog qhov ua tau los ntawm cov nqi sib txuam. Hauv lub neej txhua hnub, tshwj xeeb tshaj yog nyob rau hauv huab cua qhuav, tib neeg yuav hnov "hluav taws xob poob siab" thaum lawv kov lub qhov rooj thiab lub qhov rais nrog lawv txhais tes, uas yog qhov "tso tawm" rau tib neeg lub cev thaum hluav taws xob zoo li qub ntawm lub qhov rooj thiab qhov rais khaws cia. ib qho twg. Rau cov ntaub plaub thiab cov ntaub ntawv nylon tshuaj fiber ntau, qhov hluav taws xob uas muaj hluav taws xob zoo li qub tuaj yeem ua rau ntau tshaj 10, 000 volts. Qhov voltage yog siab heev, tab sis lub zog electrostatic tsis loj thiab yuav tsis hem lub neej. Txawm li cas los xij, rau qee cov khoom siv hluav taws xob, nws tuaj yeem ua rau tuag taus thiab ua rau lub cuab yeej ua tsis tiav.
GaN-raws li cov khoom siv hauv LEDs muaj kev tiv thaiv siab vim tias lawv yog cov khoom siv dav-bandgap semiconductor. Rau InGaN / AlGaN / GaN ob lub heterojunction xiav LEDs, lub thickness ntawm InGaN active txheej feem ntau tsuas yog ob peb kaum nanometers, thiab vim hais tias ob qhov zoo thiab tsis zoo electrodes ntawm LED no nyob rau tib sab ntawm lub nti, thiab qhov kev ncua deb ntawm lawv yog qhov me me, yog tias tus nqi hluav taws xob electrostatic ntawm ob qho kawg sib sau ua ke rau qee tus nqi, qhov hluav taws xob hluav taws xob hluav taws xob no yuav ua rau PN kev sib tshuam, ua rau nws cov dej ntws nce ntxiv, thiab hauv cov xwm txheej hnyav, PN junction tawg thiab luv luv, thiab LED ua tsis tiav.
Vim tias muaj kev hem thawj ntawm hluav taws xob zoo li qub, rau cov chips LED thiab cov khoom siv ntawm cov qauv saum toj no, kev ntsuas hluav taws xob zoo li qub yuav tsum raug coj mus rau qhov chaw ua haujlwm, cov tshuab, cov cuab yeej, cov cuab yeej, nrog rau cov neeg ua haujlwm cov khaub ncaws thaum ua haujlwm kom ntseeg tau tias LED tsis puas. . Tsis tas li ntawd, cov ntaub ntawv los tiv thaiv zoo li qub yuav tsum tau siv los ntawm kev ntim cov chips thiab cov khoom siv.
Qee tus neeg kuj tau txhim kho los ntawm cov khoom siv substrate, cov qauv epitaxial thiab cov qauv nti los daws qhov teeb meem ntawm kev tiv thaiv zoo li qub mus rau qhov loj. Txhawm rau daws qhov teeb meem no mus rau qhov loj, lwm qhov piv txwv yog siv Flip-Chip los ua ob qhov rov qab-rau-rov qab voltage regulator raj clamps ntawm silicon wafer ntawm ob qho kawg ntawm LED PN kev sib tshuam los tiv thaiv LED PN kev sib tshuam los ntawm kev hem thawj. ntawm hluav taws xob static. Tau kawg, los ntawm daim ntawv thov kev pom Hauv lwm lo lus, kev tiv thaiv Circuit Court kuj tuaj yeem ntxiv thaum siv LEDs.
