Ungawakhetha njani amaso esibane se-LED kwisiboniso se-LED?

Inxalenye ebalulekileyo yesiboniso se-LED yintsimbi yesibane se-LED kunye neebhodi zeeyunithi ze-LED. Ukuba kukho nayiphi na ingxaki kubo, iya kuchaphazela ngokuthe ngqo umgangatho opheleleyo wesiboniso se-LED! Ngoko ke, indlela yokwahlula umgangatho wezibane ze-LED kunye neebhodi zeeyunithi ze-LED ngumgangatho we-LED kunye neebhodi zeeyunithi ze-LED. Imiba ekhathalelwe ngabathengisi be-LED, nantsi indlela eqhelekileyo yokubona umgangatho wezibane ze-LED kunye neebhodi zeeyunithi zePCB. Ndiyathemba ukuba iya kuba luncedo kubathengisi bomboniso we-LED. Ukongezelela, umgangatho ungukumkani. Imveliso kunye nesixhobo esalayo esincinci kunye ne-shoddy nayo iyimfuneko yokwenza ngumenzi, ukuze ungonakalisi umphumo womsebenzi oqhelekileyo kunye nokugcinwa okungafunekiyo kokulandelayo. Ibhodi yeyunithi ye LED. Abanye abavelisi bebhodi yeyunithi ye-LED basebenzisa iibhodi zephepha ezingabizi kakhulu okanye iibhodi zefiber ezinecala elinye njengesibane se-LED njengezibane ze-LED ngamaxabiso aphantsi. Ngenxa yokuba zonke iibhodi ze-PCB zeglasi ziyabiza. Ekuqaleni, umahluko awunakubonwa. Ngokuqhelekileyo, ukuba awukho unyaka omnye, uya kuphuka ngenxa yomswakama, ukutshatyalaliswa kwe-ultraviolet, i-oxidation, njl., kubangela ukuba yonke ibhodi yeyunithi ye-LED ikhutshwe. Iibhodi zeyunithi ze-LED ezikumgangatho ophezulu kufuneka zibe kabini-macala onke -ngaphandle kwebhodi ye-PCB yeglasi. Nangona ixabiso liphezulu, umgangatho uqinisekisiwe. Jonga ukuba ngaba uhlobo lwezixhobo ze-IC ezisetyenziswayo luyahambelana. Yiyiphi imodeli ye-IC kunye nokuba zingaphi ii-IC ezisetyenzisiweyo, ezaneleyo ukuchaphazela umgangatho webhodi yeyunithi ye-LED. Abanye abavelisi be-LED, ukwenzela ukugcina iindleko, baya kunciphisa ngamabomu inani le-ICs ngexesha lebhodi yeyunithi yokuvelisa, okanye ixutywe nezinye iimpawu ze-IC. Iintsonto Iliso lenyama alikwazi ukwahlula umgangatho weentsimbi zesibane. Inokuthi isekelwe kuphela kwiimvavanyo zexesha elide, oko kukuthi, uvavanyo lokuguga oluthethwa ziingcali. Indlela yomenzi womboniso we-LED jikelele yile: amandla ombane phambi kwefektri, khangela ukuba isiboniso se-LED sinokusebenza ngokuqhelekileyo, asiyi kuvavanywa ixesha elide. Ngenxa yokuba ixesha elininzi kunye neendleko zabasebenzi zifuna ixesha elininzi kunye neendleko zabasebenzi. Umgangatho wokuwelda: Jonga ukuba ngaba kukho izitikha zokuvuza kwecandelo, izitikha ezingalunganga, nokuba kukho icandelo leenyawo zetyhubhu kunye neesekethi ezimfutshane ze-burrs. Khangela ukuba iplagi ngqo-in amalunga welding agudileyo kwaye angqukuva, nokuba umphezulu ibhodi icocekile kwaye icocekile, kwaye akukho welding virtual. Khangela ukuhambelana kokukhanya kokukhanya kunye nombala we-inki. Uvavanyo olunamandla ombane: Ukuhambelana kwendawo yokukhanyisa yovavanyo olunamandla ombane; ingaba uvavanyo lwamandla ombane lukhuselwe ngokufanelekileyo yi-CEM4953; Ukwakhiwa kwezinto eziphambili zezibane zesibane se-LED ezipakishweyo ziquka izibiyeli, iitshiphusi, iintsini zekristale eziqinileyo, imigca engundoqo kunye neegels zokupakisha, njl. I-SMD (i-Surface Mountain Devices) ibhekisela kwi-face-packed packaging structure i-LED, eyona nto ibandakanya i-LED (Chicled) kunye ne-PLCC izakhiwo zebhodi ye-PCB. Makhe sazise enye imeko yangoku yophuhliso lwasekhaya kwimiba yezinto zokupakisha. Indima yesibiyeli. I-PLCC (i-Plastic Leaded Chip Carrier) i-bracket yi-carrier ye-SMD yesixhobo se-LED, esidlala indima ebalulekileyo ekuthembekeni nasekukhanyeni kwe-LED. Inkqubo yokuvelisa isibiyeli PLCC ikakhulu ibandakanya iinkqubo bands impahla metal, electroplating, PPA (polybinzide) naliti ukubumba, ukugoba, ezintlanu-macala amathathu inkjet-dimensional kunye nezinye iinkqubo. Phakathi kwabo, i-electroplating, i-metal substrates, izinto zeplastiki, njl. hlala kwiindleko eziphambili zesibiyeli. Uyilo lophuculo lwesakhiwo sesibiyeli. Ngenxa yokuba i-PPA kunye nokubopha isinyithi kukuzibophelela ngokwasemzimbeni, umsantsa uya kuba mkhulu emva kwesithando somlilo esibuyisela ubushushu obuphezulu, okwenza kube lula ukuba umphunga wamanzi ungene kwisixhobo ecaleni komjelo wesinyithi ukuchaphazela ukuthembeka kokuthembeka. Ukuze kuphuculwe ukuthembeka kwemveliso ukuhlangabezana nomgangatho ophezulu wezixhobo zokubonisa i-LED ezihlangabezana neemfuno zemarike ephezulu, ezinye iifektri zokupakisha ziye zaphucula uyilo lwesibiyeli, njengokwamkela uyilo oluphezulu lwesakhiwo esingenamanzi, ukugoba kunye nezinye iindlela yandisa umphunga wamanzi wesibiyeli kwindlela engena kwindlela eya endleleni. Kwangaxeshanye, amanyathelo amaninzi angangeni manzi njengamatanki angangeni manzi, amanyathelo angangeni manzi, kunye nemingxuma engenamanzi yongezwa ngaphakathi kwisibiyeli. Olu luyilo alugcini nje kuphela iindleko zokupakisha, kodwa luphucula ukuthembeka kwemveliso. Okwangoku, isetyenziswe ngokubanzi kwiimveliso zokubonisa ze-LED zangaphandle. Emva kokupakishwa kunye nezibiyeli eziqhelekileyo zokuvavanya i-qi ye-bracket ye-LED eyenzelwe yi-SAM (i-Scanning Acrentic Microscope). I-chip ye-LED ingundoqo wamaso wesibane se-LED, kwaye ukuthembeka kwayo kugqiba ubomi kunye nokusebenza okukhanyayo kwamaso wesibane se-LED kunye nomboniso we-LED. Iindleko zeeakhawunti ze-chip ze-LED zexabiso lilonke lesixhobo se-LED likhulu kakhulu. Ngokuhla kweendleko, ubungakanani be-chip ye-LED bube buncinci kwaye buncinci, kwaye buzisa uluhlu lwemiba yokuthembeka. Ngokunciphisa ubungakanani, i-PAD ye-P electrode kunye ne-N electrode nayo iyancipha. Ukunciphisa i-PAD ye-electrode kuchaphazela ngokuthe ngqo umgangatho womgca we-welding. Ngexesha elifanayo, umgama we-A phakathi kwee-PAD ezimbini uya kuncipha, okuya kubangela ukuba i-electrode yangoku ikhulise ngokugqithisileyo ubuninzi bangoku, i-current iqokelela kwindawo kwi-electrode. Ukuqaqamba okugqithisileyo, ukuqaqamba okungalinganiyo, ukuvuza lula, ukuhla kwe-electrode, kunye nokusebenza kakuhle kokukhanya okuphantsi, njl. njl., ekugqibeleni kukhokelele ekunciphiseni ukuthembeka kwesiboniso se-LED. Umgca obalulekileyo ungenye yezinto eziphambili zokupakishwa kwe-LED. Umsebenzi wayo kukuqonda uxhulumaniso lombane lwe-chip kunye nezikhonkwane, ezidlala indima ye-chip kunye nehlabathi langaphandle. Isixhobo se-LED sifaka imigca engundoqo eqhelekileyo kuquka igolide, iingcingo zobhedu, imigca yobhedu efakwe ubhedu, kunye nemigca yealloyi, njl. (1) Igolide. Umgca wegolide usetyenziswa ngokubanzi, inkqubo ivuthiwe, kodwa ixabiso liyabiza, okubangela iindleko eziphezulu zokupakishwa kwe-LED. (2) Umsonto wobhedu. Imicu yobhedu ineenzuzo zexabiso eliphantsi, imiphumo emihle yokutshatyalaliswa kobushushu, kunye nokukhula okucothayo kweekhompawundi ze-metal intervertebral ngexesha lomgca we-welding. Ububi kukuba i-copper ilula uku-oxidize, ubunzima obuphezulu, kunye noxinzelelo oluphezulu. Ngokukodwa kwindawo yokufudumeza i-keyhearted copper egcadiweyo yebhola, umphezulu womhlaba wobhedu ulula kakhulu kwi-oxidize, kwaye ifilimu ye-oxide eyenziwe inciphisa ukusebenza kwe-album yocingo lobhedu. Oku kuphakamisa iimfuno eziphezulu zolawulo lwenkqubo kwinkqubo yemveliso yokwenene. (3) Ukugquma ucingo lobhedu. Ukuze kuthintelwe i-oxidation yeingcingo zobhedu, i-copper-plated copper wire ngokuthe ngcembe yatsala ingqalelo yoshishino lokupakisha. Iingenelo zamandla omatshini aphezulu, ubulukhuni obuphakathi, i-welded kakuhle kunye ne-sphere-size-sphere ifanelekile kwi-high-density, i-multi-footed-multi-footed integrated circuit package. Okwangoku, iglue egqunywe sisixhobo sokubonisa i-LED ikakhulu ibandakanya iindidi ezimbini ze-epoxy resin kunye nesilicon silicon. (1) i-epoxy resin. I-epoxy resin ithanda ukuguga, kulula ukuba manzi, ukumelana nobushushu, kwaye kulula ukuyitshintsha umbala ekukhanyeni okufutshane kunye nobushushu obuphezulu. Inetyhefu ethile kwimeko yeglue. Uxinzelelo lwe-thermal aluhambelani ne-LED. Ke ngoko, i-epoxy resin ihlala ikhubekisa. (2) I-Organic silicon. Xa kuthelekiswa ne-epoxy resin, i-silicon ye-organic inexabiso eliphezulu-ukusebenza, ukugquma okugqwesileyo, i-dielectricity, kunye nokusondelana. Kodwa into engalunganga kukuba ukuxinana kwegesi kubi, kwaye kulula ukufunxa. Ke ayifane isetyenziswe kwipakethe yesixhobo sokubonisa i-LED.
