Chip ke Eng e Loketseng Li-LED tsa Matla a Phahameng?

Ke taba e qhekellang hore bahlahisi le bareki ba bang ba LED ba khethe chip ea LED e nang le matla a phahameng le ho khetha chip e loketseng ea matla a phahameng a LED. Re akarelitse mekhoa e meng bakeng sa litšupiso tsa hau. Ea pele: eketsa mokhoa oa boholo. Eketsa sebaka se sebetsang hantle se nang le khanya ea LED e nang le khanya e le 'ngoe, ho khothalletsa ho ajoa ha junifomo ea hona joale ea lera la TCL, le mohaho o khethehileng oa li-electrode (hangata li-electrode tse kopantsoeng) ho finyella keketseho ea boholo ba phallo e lebelletsoeng ea phallo ea makenete. Leha ho le joalo, ho eketsa sebaka sa mabone ho ke ke ha rarolla bothata ba tšebeliso ea mocheso le leseli la mathata a mantlha, 'me ha ho khonehe ho fihlela phello e lebelletsoeng ea welding le kopo ea' nete. Ea bobeli: Silicon bottom plate reverse mokhoa. Pele ho tsohle, ho tlameha ho ba le chip e kholo ea boholo bo boholo ba LED e loketseng li-electrode tse tloaelehileng tsa kristale. Ka nako e ts'oanang, lokisetsa boholo bo lekanang ba silicon botlaaseng, hlahisa khauta co -crystal welded layer le conductive conductive layer (ultrasonic golden ball connector). Ebe, chip ea boholo bo boholo ba LED ea sesebelisoa se tloaelehileng sa kristale se chesetsoa ka silicon substrate welding hammoho. Sebopeho sena se utloahala haholoanyane, ke hore, bothata ba ho khantša, le bothata ba ho senya mocheso bo 'nile ba nkoa. Ea boraro: Mokhoa oa phetoho ea karoloana ea Sapphire. Ka mor'a hore lefito la PN la sapphire substrate ho ea ka mokhoa oa setso, tlosa chip ea Ingan e ntseng e hōla holim'a sapphire substrate, ebe o ikopanya le lisebelisoa tse tloaelehileng tsa li-yuan tse 'nè ho etsa chip e kholo ea boholo bo boputsoa ba LED e nang le mohaho o phahameng oa electrode. Ea bone: Mokhoa oa ho khutlisa poleiti e ka tlase ea ceramic. Pele sebelisa LED chip feme kakaretso sesebediswa ho hlahisa e khōlō-scale khanya LED chip e loketseng bakeng sa tloaelehileng kristale tjheseletsa eleketrode sebopeho le e tsamaellanang le mokatong oa ceramic le co -crystal tin conduitment lera tlhahiso. Sebelisa chip ea boholo bo boholo ba LED ho tjheseletsa ka chip ea boholo bo boholo ba LED ka har'a lisebelisoa tse tloaelehileng tsa kristale. Sebopeho sena se nahanela bothata ba leseli, 'me se nahanela bothata ba ho senya mocheso,' me se sebelisa lipoleiti tsa ceramic tse tsamaisang mocheso o phahameng, lipoleiti tsa ceramic, le phello ea ho senya mocheso e ntle haholo, 'me theko e batla e le tlaase. Ka hona, e loketse haholoanyane substrate ea hona joale. Ho setse sebaka sa ho kenya.
