I-LED Lamp Disassembly kanye nama-Welding Techniques Alapha!

Embonini ye-LED, ekusetshenzisweni kwesicelo nokuhlola ubuhlalu bezibani eziningi ze-LED, ukulimala kobuhlalu besibani kuvame ukuhlangana. Ngakho-ke yini ukubhidliza ubuhlalu besibani se-LED nokushintshwa? Indlela ukususa ubuhlalu isibani? Shintshanisa amakhono okushisela isichibi se-LED? Okulandelayo, ngizokubolela lawa maphuzu amathathu. Ungaqaqa kanjani ubuhlalu besibani se-aluminium substrate LED? Manje ubuhlalu besibani bushintshe kancane kancane ubuhlalu besibani obufakwe ngqo. Ngenxa yokuthi azikho izikhonkwane eziqondile, ubuhlalu besibani bungadluliswa ukushisela emuva, futhi i-substrate ye-aluminium ingacatshangelwa ngokukhipha ukushisa okungcono. Inhlekelele. Ngokuvamile, i-aluminium substrate LED isibani ubuhlalu kulula kakhulu ukusebenzisa ithebula le-welding yokushisisa. Inqobo nje uma ukusebenza kushisiswe kuze kufike kuma-degree angama-260, ungasusa ubuhlalu besibani ku-aluminium substrate, bese ufaka esikhundleni sayo ngobuhlalu besibani esisha se-LED. Yiqiniso, uma amakhono akho okushisela insimbi enhle, ungasebenzisa futhi i-soldering iron ukuze uyishise, futhi uyishintshe ibe ubuhlalu besibani se-LED. Lokhu kudinga imisebenzi emihle yobuchwepheshe. Umkhiqizi uncoma indlela engcono yokuhlakaza ama-aluminium substrates. Kungcono ukukhetha indlela yesikhulumi sokushisa. Lena yi-novice futhi kulula ukufunda ukuyiqaqa nokufaka esikhundleni sayo. Indlela ukususa ubuhlalu isibani? I-aluminium substrate LED ubuhlalu isibani kufanele ihlukaniswe izinhlobo ezimbili. Nokho, uma kuwubuhlalu obukhanyayo, uma ufuna ukubususa, awukwazi ukusebenzisa indlela yokushisisa ithebula lokushisela elingenhla. Ngoba izinga lokushisa lokulingisa ubuhlalu bokukhanya ngokuvamile liyi-lens ye-PC ephezulu yokushisa, engadlula kuphela ama-200-210 degrees, ngakho awukwazi ukuyibeka endaweni yokushisa. Indlela yokuqaqa ubuhlalu obugelezayo? Ngokuvamile, kusetshenziswa i-ayina e-soldering, kuqala kushisise i-ayina e-soldering ukuze kukhishwe ubuhlalu bokukhanya bokulingisa bangempela, bese kuhlanzwa isixhumi esibonakalayo sokushisela esisekelwe ku-aluminium sokuqala bese sisenza isicaba. Lapho usebenza, ungabeka ubuhlalu besibani obusha buqonde ku-electrode eyi-negative yasekuqaleni, bese wengeza i-solder encane endaweni yokushisela. Bese usebenzisa umnyuzi ukucindezela ubuhlalu besibani ukuze ushisele izinyawo. Lapho u-welding, inani elithile le-solder kufanele lithwalwe ekhanda le-welding. Uma usebenza, ungasebenzisa i-soldering iron ukuze uhlanganiswe izikhathi ezingu-2-3 kumaphedi amabili kuma-pads amabili. Ungabi nesikhathi eside kakhulu. Ngokuvamile, kungcono ukuthi ungadluli imizuzwana emi-3. Lokhu kubaluleke kakhulu, kulula ukwenza ubuhlalu bezibani bulenga emoyeni futhi buthinte ukuchithwa kokushisa okubangelwa ukuchithwa kokushisa noma ukushisa ubuhlalu besibani. Ngaphezu kwalokho, ngaphambi kokubeka ubuhlalu besibani obusha, kungcono ukusebenzisa amafutha e-silicon eshisayo kumaphedi ayindilinga phakathi ukuze unciphise ukumelana nokushisa. Isinyathelo esilandelayo se-welding kufanele siqale ngemuva, ngoba amaphedi angaphambili adinga ukupholisa nokupholisa, insimbi ye-soldering ayikwazi ukufakwa ngokuqhubekayo, ngaphandle kwalokho kulula ukushisa ubuhlalu besibani. Kulula ukushisa i-glue yesibani esishisiwe ngesibhamu somoya oshisayo, ngakho-ke ukushisela ukukhanya kungenziwa kangcono. Lokhu akudingi ukuba kuqine kakhulu ngezidingo zobuchwepheshe, ngoba umthamo wobuhlalu bokukhanya bokulingisa bukhulu ngokuqhathaniswa. Uma nje kunobuchwepheshe obuthile bokushisela insimbi obusebenzayo, bungasetshenziswa. Indlela engenhla kanye nezindlela zokushisela zokuqaqa ubuhlalu bezibani zikhona lapha. Uma udinga ukwazi ulwazi olwengeziwe, sicela uqhubeke nokusinaka. Uma udinga ukuthenga ubuhlalu besibani se-LED, ungaxhumana nabasebenzi abasemthethweni benkonzo yamakhasimende ku-inthanethi. hlinzeka ngesixazululo.
