Ungabushintsha Kanjani Ubuhlalu Besibani Se-SMD Ebhodini Lamalambu

Kukholakala ukuthi abangani abenza i-SMT ukushintsha ubuhlalu bezibani bavame ukuhlangana nabo. Ibha yethu yesibani esiqedwe semi-finished SMT izovela kulambu elilodwa noma amabili angajwayelekile ngesikhathi sokuhlolwa. Ngenxa yomklamo wesifunda, amabhodi amaningi wesifunda aklanyelwe emgwaqeni owodwa, futhi ubuhlalu besibani obungavamile buzophinde buthinte isibani esingemuva kwesibani ngemuva. Ukusetshenziswa okuvamile kwe-bead, ngalesi sikhathi sidinga ukufaka esikhundleni se-bead yesibani esisodwa. Kukhona okufakiwe okumbalwa manje, empeleni konke kukhona “Isitika sethebula ”uhlobo. Ngenxa yokuthi izinyawo aziholwanga, ama-LED angasondelana ne-substrate, futhi izimo zokushisa ukushisa ziye zathuthukiswa ngokuphelele. Impela kungenxa yokuthi akukho “unyawo ”Iphinde ilethe ukuphazamiseka okuningi ekufakeni esikhundleni sokulungisa. Ake sikuthathe uqonde indlela elungile nesebenzayo yokubuyisela ubuhlalu besibani esisodwa. Ukuze wenze umsebenzi omuhle wokushintsha ubuhlalu, kufanele ugeze izandla zakho kuqala ukuze unciphise ukumelana kwesikhumba ukuze uvikele ubuhlalu besibani ekulimazeni i-electrostatic. Futhi lungiselela amathuluzi alandelayo nezinto zokwakha, ungaqala ukwakha: Isibhamu somoya oshisayo singakhetha okuvame ukusetshenziselwa ukugcinwa. Ama-Mondrers notshwala asetshenziselwa ukusiza ukushiselwa. Ukuwela i-rosin notshwala kungancibilika. I-sinus isetshenziselwa ukulungiswa kanye nemiphumela yokuqhuba ama-lamp pads. Ubuhlalu besibani se-LED okufanele bushintshwe ngokuvamile buhlukaniswe ngokulandelayo: inkulumo yokuqala mayelana nokulingisa ubuhlalu obugelezayo. Ngenxa yokuthi lolu hlobo lobuhlalu besibani lusendaweni ekhanyayo, kulula ukubushintsha. Okokuqala, sebenzisa i-soldering iron ukuze ushise amalunga amabili e-solder ukuze ususe izibani ezimbi, bese usebenzisa i-soldering iron ukuze unciphise amaphedi amabili. Bese ufaka ubuhlalu besibani obusha ku-electrode yasekuqaleni eyiphozithivu nenegethivu ukuya kowangempela, bese ushiselwe kancane ezikhonweni. Cindezela ubuhlalu besibani ngeminwe yakho ukuze ubushisele. Kufanele kube nenani elithile le-solder ekhanda le-soldering iron ngesikhathi sokushisela. Uma usebenza, ungasebenzisa i-soldering iron ukuze uvule ngokushesha amaphedi amabili ukuze ashiselwe izikhathi ezi-2 kuya kwezi-3. Lokhu kubalulekile, ngaphandle kwalokho kulula ukubangela ukuthi ubuhlalu bumise umoya ukuze kuthinte ukuchithwa kokushisa. Ukwengeza, kungcono kakhulu ukusebenzisa i-conductivity ethile yokushisa ku-pad eyindilinga phakathi ukuze unciphise ukumelana nokushisa ku-pad eyindilinga phakathi ukuze kuncishiswe ukumelana nokushisa. Shintshanisa isigaba 5050 “Isitika sethebula ”(Futhi kwaziwa ngokuthi i-SMD) Ubuhlalu obukhanyayo buzobukeka bunzima. Ukusebenzisa izibhamu zomoya oshisayo nezinsimbi zikagesi ezifakwa phansi, inqobo nje uma i-substrate ye-aluminium ingabhujiswa. Bese usebenzisa i-soldering iron ukuze ususe ukushisela ngokweqile futhi ushiye ungqimba oluncane kuphela. Isinyathelo esilandelayo se-welding kufanele siqale ngemuva, ngoba amaphedi angaphambili ayinsimbi efihliwe kakhulu, futhi isibhamu somoya oshisayo sizoshiswa kalula nge-collagen yobuhlalu besibani. Thola ukuma kobuhlalu besibani ngemuva kwe-aluminium substrate, futhi uyishise ngethayela elikhulu noma isibhamu somoya oshisayo kuze kuncibilike i-weld yangaphambili ukushisela ubuhlalu besibani. Ngobuhlalu besibani obukhudlwana obufana no-5730, ngaphezu kwamalunga amabili ashiselwe amele izigxobo ze-LED, kuzoba namaphedi aqondene ngqo nokukhishwa kokushisa phakathi. Shisa. Yiqiniso, ungasebenzisa izibani ze-aluminium noma ezinye izinto ezishisayo ukushisa ama-substrates e-aluminium. Nokho, ngezinye izikhathi ukulimaza ubuhlalu besibani akusho ukuthi kushintshwe. Uma ubuhlalu besibani obuhambisanayo obungaphezu kuka-5 bungasuswa ngokuqondile, ubuhlalu besibani obubi bungasuswa ngaphandle kokuvuselelwa; Isifunda esifushane. Kulezi zindlela ezimbili ezingenhla, eyokuqala izokwandisa ubuhlalu obukhanyayo obusele, inani lokufana, elincane, futhi asikho isidingo sokucatshangelwa. Indlela yesibili ayinawo umthelela ebuhlalu besibani obusele. Kodwa into eyodwa efanayo ukuthi ubuso besibani buzovela kumachashazi amnyama noma ezindaweni ezimnyama, okuthinta ubuhle bonke. Okungenhla kuyindlela esivame ukushintsha ngayo ubuhlalu besibani. Ngiyethemba ukukusiza. Ingumkhiqizi wobuhlalu besibani se-LED onamalungelo obunikazi amaningi kazwelonke. Imikhiqizo eyinhloko i-LED yokukhanya okunsomi, ubuhlalu besibani se-infrared LED, ubuhlalu besibani se-ultraviolet LED, ubuhlalu besibani se-LED obunemibala, njll. Okukhulu. Uma udinga ukufunda okwengeziwe ngobuhlalu besibani se-LED, ungathintana nesevisi yamakhasimende!
