Igikorwa cyo gukora amasaro ya LED

Igikorwa cyo kubyaza umusaruroLED amatarani ihuriro ryingenzi mu nganda zimurika LED. LED yamashanyarazi, izwi kandi nka diode isohora urumuri, nibintu byingenzi bikoreshwa muburyo butandukanye uhereye kumatara yo guturamo kugeza kumashanyarazi n'ibisubizo byinganda. Mu myaka yashize, kubera ibyiza byo kuzigama ingufu, kuramba, no kurengera ibidukikije amasaro ya LED yamatara, ibyifuzo byabo byiyongereye cyane, biganisha ku iterambere n’iterambere ry’ikoranabuhanga ribyara umusaruro.

Igikorwa cyo gukora amasaro ya LED yamatara arimo ibyiciro byinshi, uhereye mugukora ibikoresho bya semiconductor kugeza kunteko ya nyuma ya chip ya LED. Inzira itangirana no guhitamo ibikoresho byera cyane nka gallium, arsenic, na fosifore. Ibi bikoresho byahujwe muburyo bugaragara kugirango habeho kristu ya semiconductor ikora ishingiro ryikoranabuhanga rya LED.

Nyuma yuko ibikoresho bya semiconductor bimaze gutegurwa, binyura muburyo bukomeye bwo kweza kugirango bikureho umwanda no kuzamura imikorere. Ubu buryo bwo kweza butuma amasaro ya LED atanga urumuri rwinshi, amabara ahoraho, hamwe nuburyo bukoreshwa. Nyuma yo kwezwa, ibikoresho bigabanywa muri wafer ntoya ukoresheje icyuma cyateye imbere.

Intambwe ikurikira mubikorwa byo kubyara ikubiyemo gukora chip ya LED ubwabo. Wafers ivuwe neza hakoreshejwe imiti yihariye kandi ikorerwa inzira yitwa epitaxy, aho ibice bya semiconductor bishyirwa hejuru ya wafer. Uku kubitsa gukorerwa mubidukikije bigenzurwa hakoreshejwe tekinike nkicyuma-kama ya chimique yamashanyarazi (MOCVD) cyangwa epitaxy ya molekulari (MBE).

Nyuma ya epitaxial inzira irangiye, wafer ikeneye kunyura murukurikirane rwa Photolithography hamwe nintambwe yo gutondeka kugirango isobanure imiterere ya LED. Izi nzira zirimo gukoresha tekinoroji ya Photolithography yubuhanga kugirango ikore ibishushanyo bigoye hejuru ya wafer isobanura ibice bitandukanye bigize chip ya LED, nkubwoko bwa p-nubwoko bwa n, uturere dukora, hamwe nudupapuro twandikirwa.

Imashini za LED zimaze gukorwa, zinyura muburyo bwo gutondeka no kugerageza kugirango zireme ubuziranenge n'imikorere. Chip irageragezwa kubiranga amashanyarazi, umucyo, ubushyuhe bwamabara, nibindi bipimo kugirango byuzuze ibisabwa. Imipira ifite inenge yatoranijwe mugihe chip ikora ikora murwego rukurikira.

Mu cyiciro cya nyuma cyumusaruro, chip ya LED ipakirwa mumasaro yanyuma ya LED. Uburyo bwo gupakira burimo gushira chip kumurongo wambere, kubahuza kumashanyarazi, no kubishyira mubikoresho birinda ibintu. Iyi paki irinda chip kubintu bidukikije kandi byongera igihe kirekire.

Nyuma yo gupakira, amatara ya LED yamashanyarazi akorerwa ibizamini byinyongera, biramba, kandi byizewe. Ibi bizamini bigereranya imikorere nyayo kugirango hamenyekane ko amasaro ya LED akora neza kandi ashobora kwihanganira ibintu bitandukanye bidukikije nko guhindagurika kwubushyuhe, ubushuhe, hamwe no kunyeganyega.

Muri rusange, uburyo bwo gukora amasaro ya LED yamatara biragoye cyane, bisaba imashini zigezweho, kugenzura neza, no kugenzura ubuziranenge. Iterambere mu ikoranabuhanga rya LED no kunoza imikorere y’umusaruro ryagize uruhare runini mu gutuma urumuri rwa LED rushobora gukoreshwa neza, ruramba, kandi rwizewe. Hamwe nubushakashatsi buhoraho hamwe niterambere muri uru rwego, biteganijwe ko umusaruro uzarushaho kunozwa, kandi amashanyarazi ya LED azakora neza kandi ahendutse mugihe kizaza.

Niba ushishikajwe no gukora amasaro ya LED yamatara, ikaze hamagara LED ikora umuhanda wo mu muhanda TIANXIANG kurisoma byinshi.
