Isaziso Sokufaka Isicelo Se-Luminous Diode 3535

Ubuhlalu besibani se-3535 Ubuhlalu besibani se-LED bunenzuzo eyingqayizivele, kodwa ubuhlalu besibani se-LED buwumkhiqizo osengozini ye-semiconductor, ngakho-ke kufanele siqaphele lapho sisebenzisa imikhiqizo ye-LED. Manje sizofingqa ezinye zezinyathelo zokuphepha zokusetshenziswa kwe-LED. Sicela unamathisele ukubaluleka okukhulu kukho. (1) Ukunikezwa kukagesi kufanele kusetshenziswe ekuphakeleni kukagesi kwe-DC. Abanye abakhiqizi babakhiqizi kufanele basetshenziswe ukuze kwehliswe izindleko zomkhiqizo. “Ukuphikisana ”Amandla emikhiqizweni ye-LED ngendlela, ezothinta ngqo impilo yemikhiqizo yesibani se-LED. Ukwamukela ukunikezwa kwamandla okushintshwa okukhethekile (okungcono kube umthombo wokusakaza njalo) ukunikezwa komkhiqizo emikhiqizweni yobuhlalu besibani se-LED ngeke kuthinte impilo yesevisi yomkhiqizo, kodwa izindleko zomkhiqizo ziphezulu uma kuqhathaniswa. (2) Izinyathelo zokulwa nogesi kumele zithathwe ngesikhathi sokucutshungulwa kanye nokukhiqizwa kobuhlalu bezibani ze-LED. Amagilavu, njll., lawo anezimo angafakwa namafeni e-anti-static ion, futhi aqinisekise umswakama wendawo yokusebenzela cishe u-65%, ukuze kugwenywe umoya ukuba wome kakhulu ukukhiqiza ugesi omile, ikakhulukazi oluhlaza. Ubuhlalu besibani se-LED kulula ukulinyazwa ngomonakalo we-electrostatic. Ngaphezu kwalokho, amakhono ahlukene wekhwalithi -grade LED anti -static nawo ahlukile. Ubuhlalu bezibani ze-LED ezinezinga eliphezulu kufanele zibe namandla. Kungase kube nenqwaba yabangane abangawazi kahle ugesi omile. Ngizokwethula ulwazi logesi omile ngokuningiliziwe lapha: ingqikithi kagesi ongashintshi inkokhiso eningi. Ukushaja inani elibonakalayo layo yonke ingqikithi kagesi omile. IsiNgisi sibizwa nge-ESD. Amanani ahlobene ahlobene namandla, inkambu kagesi, yamanje, njll. wonke amanani abonakalayo okubangwa ukuba khona kwenkokhiso noma ukunyakaza kwenkokhiso. Izinkinga eziningi ze-electrostatic zidalwa abantu abangenakho ukwazi kwe-ESD. Ngisho namanje, abantu abaningi basola ukuthi i-ESD izodala umonakalo emikhiqizweni kagesi. Lokhu kungenxa yokuthi umonakalo omningi we-ESD wenzeka ngaphansi komzwelo womuntu, ngenxa yokuthi i-voltage ebonwayo yomzimba womuntu yokukhipha i-static cishe i-3KV, futhi izingxenye eziningi ze-elekthronikhi zizolimala uma zingamakhulu ama-volts noma inqwaba yama-volts. Ngokuvamile, lapho izinto zikagesi zilinyazwa yi-ESD Awukho umngcele osobala, futhi ingxenye ifakwa ku-PCB ngaphambi kokutholwa. Ngenxa yalokho, kunezinkinga eziningi, futhi ukuhlaziya kunzima kakhulu. Ikakhulukazi ngomonakalo ongase ube khona, kunzima ukukala ukusebenza kwawo ngisho namathuluzi anembayo, ngakho bobabili onjiniyela be-elekthronikhi nabaklami basole i-ESD. Eminyakeni yamuva nje, ukuhlolwa kuqinisekisile ukuthi lo monakalo ongaba khona uzoba Ukuthembeka kuncipha kakhulu. (3) Izinga lokushisa le-LED ubuhlalu kufanele linake ukwanda kwezinga lokushisa lizokwenza ukumelana kwangaphakathi kwezibani ze-LED zibe zincane. Ngemuva kokuthi izinga lokushisa lemvelo lezwe langaphandle likhuphuka, ukumelana kwangaphakathi kobuhlalu besibani se-LED kuzoncishiswa. Ukukhuphuka kwamanje, lapho ukusebenza kwamanje kudlula umsebenzi wayo olinganiselwe, kuzothinta impilo yesevisi yemikhiqizo ye-LED, okuzobangelwa kakhulu ubuhlalu besibani se-LED. “Ukushisa ”Ngakho-ke, kungcono kakhulu ukusebenzisa amandla omthombo we-Hengli ukuze uqinisekise ukuthi ukusebenza kwamanje kwe-LED akuthintwa ukushisa kwangaphandle. Izinga lokushisa lobuhlalu belambu le-LED liphinde libe yisici esibaluleke kakhulu esithinta impilo ye-LED. Sicela unake. (4) Ukubekwa uphawu kwemikhiqizo yesibani se-LED, kungakhathaliseki ukuthi umkhiqizo wobuhlalu besibani se-LED, inqobo nje uma usetshenziswa ngaphandle, ubhekene nenkinga yokungangeni kwamanzi kanye nezinkinga zokuvala umswakama. Uma ingaphathwa kahle, izothinta ngqo impilo yesevisi yemikhiqizo ye-LED. Manje kunenani elincane labakhiqizi abanezidingo zekhwalithi ephezulu abasebenzisa i-epoxy resin yendabuko “Amanzi ”Indlela yokuvala imikhiqizo ye-LED. Le ndlela inzima kakhulu ukusebenza. Ayifaneleki kakhulu emikhiqizweni yobuhlalu besibani se-LED enomthamo omkhulu, futhi izokwandisa nesisindo somkhiqizo. (5) Umsinga wobuhlalu besibani se-LED awukwazi ukudlula i-IF yamanje yobuhlalu besibani se-LED. (6) Ubuhlalu besibani se-LED kumele bunake ubuhlalu besibani se-LED akumele busondele kakhulu ku-colloid lapho ikhona noma i-engeli igobile. Kufanele igcinwe ebangeni elingaphezu kuka-2mm ukusuka ku-colloid. Inombolo yokugoqa endaweni ayikwazi ukuba ngaphezu kwezikhathi ezintathu, futhi ikhoneni ligobekile 90 °Buyela endaweni yokuqala kanye. (7) Izinga lokushisa lokushisela le-welding lingaba ngu-260 C, isikhathi silawulwa phakathi kwama-5s, futhi iphuzu lokushisela lingaphezu kuka-2.5mm ukusuka phansi kwe-colloid.
