1. Uhlobo lwe-welding
Ngokubanzi, ukuwelda kunokwahlulwa ngokweendidi ezintathu: ukuwelda intsimbi yombane, ukuwelda iqonga lokufudumeza kunye ne-reflow soldering welding:
a: Eyona ndlela ixhaphakileyo yi-soldering yombane, njengokubumba kunye nokulungisa izinto ze-elektroniki.Kule mihla, abavelisi be-LED, ukuze balondoloze iindleko zabo zokuvelisa, baninzi basebenzisa iintsimbi zombane zomgunyathi kunye ne-shoddy, okukhokelela ekudibaneni okungalunganga kwaye ngamanye amaxesha ukuvuza.Ngexesha lenkqubo yokuwelda, oku kulingana nokwenza isekethe phakathi kwencam yentsimbi evuzayo - i-LED edayiweyo - umzimba womntu - kunye nomhlaba, oko kukuthi, amandla ombane angamashumi ukuya kumakhulu amaxesha amakhulu kunombane okhoyo. ngamaso isibane isetyenziswa amaso isibane LED, ngoko nangoko batshise ngaphandle.
b: Ukukhanya okufileyo okubangelwa i-welding kwi-platform yokufudumeza kuye kwaba sisixhobo esihle kakhulu sokuvelisa kumashishini amaninzi ukwenzela ukuhlangabezana neemfuno zeebhetshi ezincinci kunye nemimiselo yeesampuli ngenxa yenani eliqhubekayo lee-odolo zeesampuli zesibane.Ngenxa yeenzuzo zeendleko zexabiso eliphantsi, ulwakhiwo olulula kunye nokusebenza, iqonga lokufudumeza libe sesona sixhobo silungileyo sokuvelisa, Ngenxa yendawo yokusetyenziswa (ezifana nengxaki yokungazinzi kobushushu kwiindawo ezinamafeni), ubuchule babaqhubi be-welding, kunye ukulawulwa kwesantya se-welding, kukho ingxaki ebalulekileyo yezibane ezifileyo.Ukongezelela, kukho ukusekwa kwezixhobo zeqonga lokufudumeza.
c: I-Reflow soldering iyona ndlela yokuvelisa ethembekileyo, efanelekileyo kwimveliso yobuninzi kunye nokulungiswa.Ukuba umsebenzi awufanelekanga, uya kubangela iziphumo ezinzulu zokukhanya ezifileyo, ezifana nokulungiswa kobushushu obungenangqiqo, ukumisa umatshini ongalunganga, njl.
2. Indawo yogcino ebangela izibane ezifileyo
Oku kwenzeka rhoqo.Xa sivula ipakethe, asiyi kuqwalasela amanyathelo obungqina bokufuma.Uninzi lwamaso esibane kwimarike ngoku atywinwe ngejeli yesilica.Esi sixhobo siya kutsala amanzi.Nje ukuba amaso esibane achaphazeleke kukufuma, ijeli yesilica iya kwandiswa kwethermal emva kwewelding yobushushu obuphezulu.Ucingo lwegolide, itshiphu kunye nesibiyeli ziya konakala, kubangele ukufuduswa kunye nokuqhekeka kocingo lwegolide, kwaye indawo yokukhanya ayiyi kukhanyiswa, Ngoko ke, kuyacetyiswa ukuba kugcinwe ii-LED kwindawo eyomileyo nengenamoya, kunye nobushushu bokugcina - 40 ℃ -+100 ℃ kunye nokufuma okungaphantsi kwama-85%;Kucetyiswa ukuba usebenzise i-LED kwimeko yayo yangaphambili yokupakisha ngaphakathi kweenyanga ezi-3 ukuphepha ukurusa kwesibiyeli;Emva kokuba isikhwama sokupakisha se-LED sivulwe, kufuneka sisetyenziswe ngokukhawuleza.Ngeli xesha, ubushushu bokugcina yi-5 ℃ -30 ℃, kwaye ukufuma okuhambelanayo kungaphantsi kwe-60%.
3. Ukucoca imichiza
Musa ukusebenzisa ulwelo lweekhemikhali ezingaziwayo ukucoca i-LED, njengoko inokonakalisa umphezulu we-colloid ye-LED kwaye ibangele nokuqhekeka kwe-colloid.Ukuba kukho imfuneko, nceda ucoce nge-alcohol swab kwiqondo lobushushu begumbi nakwindawo engena umoya, kukhethwa kumzuzu omnye wokugqitywa komoya.
4. Utshintsho olubangela ukukhanya okufileyo
Ngenxa yokuguqulwa kwezinye iipaneli zokukhanya, abaqhubi baya kwenziwa utyando lweplastiki.Njengoko iipaneli zikhubazeka, amaso okukhanya kuzo nawo ayaguquka kunye, aze aphule ucingo lwegolide kwaye abangele ukuba izibane zingakhanyi.Kunconywa ukwenza utyando lweplastiki ngaphambi kokuveliswa kolu hlobo lwepaneli.Ukudityaniswa kwexesha elide kunye nokuphathwa ngexesha lemveliso nako kunokubangela ukuguquka kunye nokuqhekeka kocingo lwegolide.Kwakhona, kubangelwa ukupakisha.Ukuze kuququzelelwe inkqubo yokuvelisa, iipaneli zezibane zifakwe ngokungaqhelekanga.Ngenxa yomxhuzulane, umaleko ongezantsi wamaso wesibane uya konakala kwaye wonakalise ucingo lwegolide.
5. Isakhiwo sokutshatyalaliswa kobushushu, ukunikezelwa kwamandla, kunye nebhodi yesibane ayihambelani
Ngenxa yokungafanelekangaukunikezwa Amandlauyilo okanye ukhetho, unikezelo lwamandla ludlula umda omkhulu onokuthi i-LED inokumelana (ngaphezu kwangoku, impembelelo yangoko);Isakhiwo esingenangqiqo sokutshatyalaliswa kokushisa kwezixhobo zokukhanyisa kunokubangela izibane ezifileyo kunye nokubola kokukhanya kwangaphambili.
6. Isiseko sefektri
Kuyimfuneko ukujonga ukuba ngaba i-wire grounding wire yefektri ikwimeko entle
7. Umbane omileyo
Umbane ongatshintshiyo unokubangela ukusilela komsebenzi we-LED, kwaye kuyacetyiswa ukuba uthintele i-ESD ekonakaliseni i-LED.
A. Ngexesha lokuvavanywa kwe-LED kunye nendibano, abaqhubi kufuneka banxibe i-bracelets anti-static kunye neiglavu ezichasayo.
B. Ukuwelda kunye nezixhobo zokuvavanya, iitafile zokusebenza, ii-racks zokugcina, njl. Kufuneka zisekelwe kakuhle.
C. Sebenzisa i-ion blower ukuphelisa umbane ongatshintshiyo owenziwe yi-friction ngexesha lokugcinwa kwe-LED kunye nokudibanisa.
D. Ibhokisi yezinto zokufakela i-LED ithatha ibhokisi ye-anti-static, kunye nengxowa yokupakisha ithatha isikhwama se-electrostatic.
E. Musa ukuba nengqondo eguquguqukayo kwaye ubambe i-LED nje.
Iziganeko ezingaqhelekanga ukuba umonakalo we-LED obangelwa yi-ESD uquka:
A. Ukubuyisela umva ukuvuza kunokubangela ukuncipha kokuqaqamba kwiimeko ezincinci, kwaye isibane sinokungalayiti kwiimeko ezinzima.
B. Ixabiso lombane wangaphambili liyancipha.I-LED ayinakukhupha ukukhanya xa iqhutywa ngumbane ophantsi.
C. Ukuwelda kakubi kwabangela ukuba isibane singakhanyi.
