Momwe Mungasankhire Mikanda ya Nyali ya LED mu Chiwonetsero cha LED?

Gawo lofunikira la chiwonetsero cha LED ndi mikanda ya nyali ya LED ndi matabwa a unit unit. Ngati aliyense wa iwo ali ndi vuto, zidzakhudza mwachindunji mawonekedwe onse a LED! Kotero, momwe mungasiyanitsire khalidwe la mikanda ya nyali ya LED ndi matabwa a unit unit ndi khalidwe la LED ndi matabwa a unit. Nkhani zomwe amalonda owonetsa ma LED amasamala nazo, nayi njira yodziwika bwino yodziwira mtundu wa mikanda ya nyali ya LED ndi ma board a unit PCB. Ndikukhulupirira kuti zikhala zothandiza kwa amalonda owonetsa ma LED. Komanso khalidwe ndi mfumu. Chogulitsa ndi chipangizo chomwe chimakana zotsika mtengo komanso zopanda pake ndizofunikanso kuchita ndi wopanga, kuti zisawononge zotsatira za ntchito yachizolowezi komanso kusamalidwa kosafunikira kotsatira. Bodi la LED. Ena opanga ma board board a LED amagwiritsa ntchito matabwa otsika mtengo oyaka moto kapena matabwa ambali imodzi ngati nyali ya LED ngati nyali za LED pamitengo yotsika. Chifukwa matabwa onse magalasi CHIKWANGWANI PCB ndi okwera mtengo. Pachiyambi, kusiyana sikungawoneke. Nthawi zambiri, ngati sichaka chimodzi, imasweka chifukwa cha chinyezi, kuwonongeka kwa ultraviolet, oxidation, ndi zina zotere, zomwe zimapangitsa kuti bolodi lonse la LED lichotsedwe. Ma board apamwamba a LED amayenera kukhala mbali zonse ziwiri za magalasi fiber PCB board. Ngakhale mtengo wake ndi wokwera, mtundu wake ndi wotsimikizika. Onani ngati mtundu wa zida za IC zomwe zimagwiritsidwa ntchito ndizofanana. Ndi mtundu wanji wa IC ndi ma IC angati omwe amagwiritsidwa ntchito, zomwe ndizokwanira kukhudza mtundu wa board ya LED. Ena opanga zowonetsera ma LED, kuti apulumutse ndalama, achepetse dala kuchuluka kwa ma IC panthawi yopanga ma unit board, kapena kusakanikirana ndi mitundu ina ya IC. Nhlamba ndi chip. Diso lamaliseche silingathe kusiyanitsa ubwino wa mikanda ya nyali. Zingathe kukhazikitsidwa pa mayesero a nthawi yayitali, ndiko kuti, kuyesa kukalamba komwe akatswiri amanena. Njira ya wopanga chiwonetsero cha LED ndi: mphamvu yopangira mphamvu pamaso pa fakitale, fufuzani ngati chiwonetsero cha LED chitha kugwira ntchito moyenera, sichingayesedwe kwa nthawi yayitali. Chifukwa nthawi yambiri ndi ndalama zogwirira ntchito zimafuna nthawi yambiri komanso ndalama zogwirira ntchito. Ubwino wowotcherera: Onani ngati pali zomata zotayikira, zomata zolakwika, komanso ngati pali machubu ndi ma burrs afupikitsa. Onani ngati pulagi mwachindunji - mu kuwotcherera mafupa ndi yosalala ndi kuzungulira, ngati bolodi pamwamba ndi woyera ndi waudongo, ndipo palibe kuwotcherera pafupifupi. Yang'anani kusasinthasintha kwa kuwala kwa kuwala ndi mtundu wa inki. Mayesero amphamvu: Kugwirizana kwa malo ounikira a kuyesa kwa mphamvu; ngati kuyesa kwa mphamvu kumatetezedwa bwino ndi CEM4953;. Zolemba zazikulu za mikanda ya nyali za LED zomwe zapakidwa zimaphatikizanso mabatani, tchipisi, chingamu cholimba cha kristalo, mizere yayikulu ndi ma gels onyamula, ndi zina zambiri. SMD (Surface Mountain Devices) imatanthawuza mawonekedwe odzaza ndi ma LED, omwe makamaka amaphatikiza ma LED (Chicled) ndi ma PLCC a board ya PCB. Tiyeni tidziwitse zachitukuko chapakhomo chapano pazinthu zonyamula katundu. Ntchito ya mbali. PLCC (Plastic Leaded Chip Carrier) bulaketi ndi chonyamulira cha chipangizo cha SMD LED, chomwe chimagwira ntchito yofunika kwambiri pakudalirika ndi kuwala kwa LED. The PLCC bulaketi kupanga ndondomeko makamaka zikuphatikizapo njira zamagulu zitsulo chuma, electroplating, PPA (polybinzide) jekeseni akamaumba, kupinda, asanu mbali zitatu -dimensional inkjet ndi njira zina. Pakati pawo, electroplating, magawo zitsulo, zipangizo pulasitiki, etc. kukhala ndi mtengo waukulu wa bulaketi. Kapangidwe kabwino ka bracket. Chifukwa PPA ndi zomangira zitsulo zimamangiriza thupi, kusiyana kwake kudzakhala kokulirapo pambuyo pa ng'anjo yobwerera kutentha kwapamwamba, zomwe zimapangitsa kuti nthunzi yamadzi ikhale yosavuta kulowa mu chipangizocho motsatira njira yachitsulo kuti iwononge kudalirika kwa kudalirika. Pofuna kukonza kudalirika kwazinthu kuti zigwirizane ndi zida zapamwamba zowonetsera za LED zomwe zimakwaniritsa zosowa za msika wapamwamba kwambiri, mafakitale ena onyamula katundu asintha mapangidwe a bulaketi, monga kutengera kapangidwe kapamwamba kopanda madzi, kupindika ndi njira zina zochitira. onjezerani nthunzi wamadzi mu bulaketi munjira yolowera munjira. Nthawi yomweyo, miyeso ingapo yopanda madzi monga akasinja osalowa madzi, masitepe osalowa madzi, ndi mabowo osalowa madzi amawonjezeredwa mkati mwa bulaketi. Kapangidwe kameneka sikumangopulumutsa ndalama zonyamula katundu, komanso kumapangitsa kudalirika kwazinthu. Pakadali pano, imagwiritsidwa ntchito kwambiri pazinthu zowonetsera zakunja za LED. Pambuyo popakidwa ndi mabatani abwinobwino kuyesa qi ya bulaketi ya LED yopangidwa ndi SAM (Scanning Acrentic Microscope). Chip cha LED ndiye pachimake cha mikanda ya nyali ya LED, ndipo kudalirika kwake kumatsimikizira moyo ndi ntchito yowala ya mikanda ya nyali ya LED komanso mawonetsedwe a LED. Mtengo wa akaunti ya chip ya LED pamtengo wokwanira wa chipangizo cha LED ndiwokwera kwambiri. Ndi kuchepa kwa mtengo, kukula kwa chipangizo cha LED kwakhala kocheperako komanso kocheperako, ndipo kumabweretsanso mndandanda wazinthu zodalirika. Ndi kuchepa kwa kukula kwake, PAD ya P electrode ndi N electrode inachepanso. Kuchepetsa kwa electrode PAD kumakhudza mwachindunji mtundu wa mzere wowotcherera. Panthawi imodzimodziyo, mtunda wa A pakati pa ma PAD awiriwo udzachepanso, zomwe zidzachititsa kuti electrode panopa iwonjezere kwambiri kachulukidwe kameneka, zamakono zimasonkhana kumaloko pa electrode. Kuwala kopitilira muyeso, kutayikira kosavuta, kutsika kwa ma electrode, komanso kuwala kocheperako, ndi zina zambiri, pamapeto pake zidapangitsa kuti chiwonetsero cha LED chichepetse kudalirika. Mzere wofunikira ndi chimodzi mwazinthu zofunikira pakuyika kwa LED. Ntchito yake ndikuzindikira kugwirizana kwa magetsi kwa chip ndi zikhomo, zomwe zimagwira ntchito ya chip ndi dziko lakunja. Chipangizo cha LED chimadzaza mizere yofunikira yodziwika bwino kuphatikiza golide, mawaya amkuwa, mizere yamkuwa yokhala ndi mkuwa, ndi mizere ya alloy, ndi zina zambiri. (1) Goldline. Mzere wa golide umagwiritsidwa ntchito kwambiri, ndondomekoyi ndi yokhwima, koma mtengo wake ndi wokwera mtengo, zomwe zimapangitsa kuti pakhale mtengo wapamwamba wa ma CD a LED. (2) mkuwa. Ulusi wamkuwa uli ndi ubwino wake wotsika mtengo, zotsatira zabwino zowonongeka kutentha, ndi kukula kwapang'onopang'ono kwazitsulo za intervertebral pazitsulo zowotcherera. Choyipa ndichakuti mkuwa ndi wosavuta kuyimitsa oxidize, kuuma kwakukulu, komanso kupsinjika kwambiri. Makamaka mu Kutentha chilengedwe cha keyhearted mkuwa wokazinga mpira, pamwamba mkuwa pamwamba n'zosavuta oxidize, ndipo anapanga okusayidi filimu amachepetsa albuming ntchito ya waya wamkuwa. Izi akupereka zofunika apamwamba kwa ndondomeko ulamuliro mu ndondomeko yeniyeni kupanga. (3) Kutenga nyama ya mkuwa. Pofuna kupewa makutidwe ndi okosijeni wa mawaya mkuwa, ndi mkuwa -yokutidwa mkuwa waya pang'onopang'ono kukopa chidwi makampani ma CD. Ubwino wa mphamvu zamakina apamwamba, kuuma kwapakati, zowotcherera bwino komanso zazikuluzikulu ndizoyenera kunyamula kachulukidwe kapamwamba, kachulukidwe kamitundu yambiri. Pakalipano, guluu wopangidwa ndi chipangizo chowonetsera cha LED makamaka amaphatikizapo mitundu iwiri ya epoxy resin ndi silicon silicon. (1) mankhwala. Epoxy resin sachedwa kukalamba, yosavuta kukhala yonyowa, yosamva kutentha, ndipo ndi yosavuta kusintha mtundu pakuwala kwafupipafupi komanso kutentha kwambiri. Lili ndi kawopsedwe kena ka guluu. Kupanikizika kwamafuta sikufanana ndi LED. Chifukwa chake, epoxy resin nthawi zambiri imakhala yokhumudwitsa. (2) Silikoni. Poyerekeza ndi utomoni wa epoxy, organic silicon imakhala ndi mtengo wokwera -yogwira ntchito bwino, kutchinjiriza kwabwino kwambiri, dielectricity, ndi kuyandikana. Koma choyipa ndichakuti kuthina kwa gasi ndikosavuta, ndipo ndikosavuta kuyamwa. Chifukwa chake sichimagwiritsidwa ntchito kawirikawiri pakuyika kwa chipangizo chowonetsera cha LED.
