Izicelo Ezibalulekile Zokwelashwa Kwe-UV LED Ensimini Ye-Microelectronics

I-UV LED  inqubo esebenzisa i-ultraviolet (UV) ukukhanya-emitting diode (ama-LED) ukwelapha noma ukomisa izinto ezinamathelayo, ama-coatings, oyinki, nezinye izinto. Inqubo ibandakanya ukudalula okokusebenza ekukhanyeni kwe-UV, okubangela ukusabela kwamakhemikhali okuholela ekuqineni noma ekwelapheni. I-UV LED  kuyinqubo esheshayo nesebenza ngempumelelo kunezindlela zokwelapha zendabuko, njengokuphulukisa okushisayo noma ukomiswa komoya. Ingasetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi eze-elekthronikhi, ezezimoto, nezokwelashwa.

Ukukhanya kwe-UV okuvela kuma-LED kuvamise ukuba ku-365nm-385nm, kunomfutho ophakeme futhi akuguquguquki kakhulu, lokhu kuvumela ukuphulukiswa okunembayo nokungaguquguquki. Iphinde ivumele inqubo esebenza kahle kakhulu njengoba ingelapheka ngemizuzwana, uma kuqhathaniswa nemizuzu noma amahora kwezinye izindlela zokwelapha. I-UV LED  futhi akukhiqizi ukushisa, okungaba yinzuzo ezinhlelweni ezithile lapho ukushisa kungaba yinkinga.

Ukwelapha kwe-UV vs Ukwelashwa kwe-UV LED. Yimiphi Imehluko Eyinhloko?

Ukwelashwa kwe-UV  ngokuvamile isebenzisa isibani se-UV noma isibani se-mercury vapor ukwelapha izinto zokwakha, kuyilapho UV   Ukukhanya kwe-LED  isebenzisa ama-UV light-emitting diode (ama-LED) ukwelapha izinto zokwakha. UV   Ukukhanya kwe-LED  ingelapheka ngemizuzwana, kuyilapho ukwelapha nge-UV kungathatha imizuzu noma amahora ukuphulukiswa. I-UV LED  iyonga amandla amaningi kunokwelapha nge-UV ngoba isebenzisa amandla amancane ukukhiqiza ukukhanya kwe-UV.

I-UV LED  isebenzisa ukukhanya kububanzi obungu-365nm-385nm, okuvumela ukuphulukiswa okungaguquguquki. Ukwelashwa kwe-UV kusebenzisa ukukhanya okubanzi okungahlukahluka kuye ngohlobo lwesibani esisetshenzisiwe. I-UV LED  inobungani bemvelo kunokwelapha nge-UV ngoba ayikhiqizi isisi esiyingozi.

Ukusetshenziswa kwe-UV LED Curing ku-Field of Microelectronics

Emkhakheni we-microelectronics, Ukwelashwa kwe-UV-LED  iglue isetshenziswa kakhulu ekubopheni nasekuvaleni izingxenye ze-microelectronic, njengezinzwa, ama-chips, nama-transistors. Iphinde isetshenziselwe ukuhlanganisa izingxenye ze-microelectronics kanye nokuhlanganiswa kwe-PCB.

Izinto ezinamathelayo ze-UV, ezaziwa nangokuthi izinto ezinamathelayo ezilapheka e-UV noma ama-sealant, ziwuhlobo lokunamathela olucushwa noma lwelashwe ngokuchayeka ekukhanyeni kwe-ultraviolet (UV). Lezi zinamathiselo zingenziwa kusuka ezinhlobonhlobo zama-polymer resins, njenge-acrylate noma i-epoxy. Uma evezwe ekukhanyeni kwe-UV, ama-monomers kulawa ma-resin ayasabela futhi enze i-polymerize, akhe isibopho esiqinile.

Ama-sealant e-UV ahlukile kuma-sealant endabuko, njengama-epoxies nama-cyanoacrylates, adinga isikhathi sokwelapha ekamelweni lokushisa noma ukushisa ukuze kwelashwe. Amaglue e-UV nama-sealant, nokho, alapha cishe ngokushesha lapho evezwe ukukhanya kwe-UV, okuwenza alungele izinqubo zokuhlanganisa ezinesivinini esikhulu, ezizenzakalelayo.

Nazi ezinye izindlela I-UV LED  kwenziwa ngama-adhesives emkhakheni we-microelectronics.

Ukuhlanganisa nokubekwa uphawu

I-UV LED  iglue isetshenziselwa ukuhlanganisa nokuvala izingxenye ze-microelectronic, ihlinzeka ngendlela esheshayo, ephumelelayo, nenembayo yokuhlanganisa nokufaka uphawu. Ukukhanya kwe-UV okuvela kuma-LED kunikeza inqubo yokwelapha esheshayo eqeda isidingo sokushisa nokucindezela, okungalimaza izingxenye ze-elekthronikhi ezibucayi. Ngenxa yalokho, lokhu kusinika imikhiqizo enethuba eliphansi kakhulu lokuba nephutha.

I-Ecapsulation

Iglue ye-UV-LED yokwelapha isetshenziselwa ukuhlanganisa izingxenye ze-microelectronic ukuze zivikeleke kumswakama, ukushisa, nezinye izici zemvelo. Ukukhanya kwe-UV okuvela kuma-LED kunikeza inqubo yokwelapha esheshayo, futhi uphawu oludaliwe alungeni umoya, lunikeza ukuvikeleka okuhlala isikhathi eside. Ngosizo lwe I-UV LED  ngeke nje kuphela ukuthi i-encapsulation ibe yekhwalithi ephezulu kodwa izokwandisa ukuphepha komkhiqizo wokugcina.

Ukuhlanganiswa kwe-PCB

Iglue yokwelapha ye-UV-LED isetshenziswa enqubweni yokuhlanganisa ye-PCB (Printed Circuit Board), lapho isetshenziselwa ukuhlanganisa izingxenye ezihlukahlukene ze-PCB ndawonye. Uma kuqhathaniswa nobuchwepheshe bendabuko obufana namaglue e-UV nama-sealant, iglue ye-UV-LED yokwelapha iyashesha, iyasebenza, futhi inembe, futhi isiza ukuthuthukisa ukusebenza nokuthembeka kwe-PCB. Sekukonke, I-UV LED  ama-sealants asiza ukwakha amabhodi e-PCB ngendlela engcono kakhulu kunaleyo imikhiqizo yangaphambilini nezimbangi zayo I-UV LED  umnikelo.

I-Adhesive Conductive

Iglue ye-UV-LED yokuphulukisa ingasetshenziswa futhi njenge-adhesive conductive, esiza ekuqedeni isidingo se-soldering, esingalimaza izingxenye ze-microelectronics. I-UV LED  iglue ikunikeza indawo yeglue yendabuko ye-UV nama-sealant. Kuhlukile ngoba lapha ama-substrates awadluliseli kubude begagasi be-UV. Ngaphezu kwalokho, okubenza babe ukukhetha okuhlukile kungenxa yokucaca kwabo okuvelele.

Izikrini zokuthinta

Abakhiqizi bamadivayisi wesikrini esithintwayo bavamise ukusebenzisa I-UV LED  i-adhesive ngaphambi komhlangano. Ingxenye enenzuzo kakhulu ukushisa okuphansi kanye nokwelapha okudingekayo okunikezwa yile nto ngamalambu e-UV LED. Isiza ukuvimbela ukulimala okungaba khona ezingxenyeni ezibucayi zengxenye eyigugu kakhulu yedivayisi ye-elekthronikhi ngokuletha umphumela ongaguquki kakhulu futhi osheshayo.

Ingabe Unentshisekelo Futhi Ekulapheni kwe-UV LED? Sinesixazululo!

I-UV LED  iwumkhakha okhulayo onamandla amaningi. Uma nawe osuqalile ukuba nentshisekelo emkhakheni we I-UV LED  futhi ungathanda ukuzihlolela yona, sinakho okuphelele Isixazululo se-UV LED  kwakho; sinomhlahlandlela ofanele wena.

I-Tiahui  ingenye ehamba phambili Abakhiqizi be-UV LED  enohlu olubanzi lwezinketho ongakhetha kuzo. Noma ngabe usembonini yezokwelapha noma umkhakha wezolimo, i-Tianhui inomkhiqizo okulungele. Kusukela I-UV LED diode  Kuyo Imodyuli ye-UV LED , sinakho konke okusengqondweni yakho. Uma ufuna ikhwalithi enenani, i-Tianui igama lomdlalo.

Eyisonga

I-UV LED  ubuchwepheshe buyashintsha ngokuphelele. Ngalokhu, amanye amathuba amaningi avuliwe. Uma kuqhathaniswa nobuchwepheshe bendabuko obufana nokwelapha kwe-UV, I-UV LED  inikeza ukusebenza okuthuthukisiwe futhi isimama kakhulu futhi.

Sithemba ukuthi lesi sihloko sibe usizo ekutholeni impendulo yemibuzo yakho mayelana nezicelo ze I-UV LED kuma-microelectronics. Ungakhohlwa ukuhlola i-Tianhui ngemikhiqizo ehamba phambili ye-UV LED.
