1. Uhlobo lwe-Welding
Ngokuvamile, i-welding ingahlukaniswa ngezinhlobo ezintathu: ukushiswa kwensimbi kagesi, ukufudumeza kwe-welding yesikhulumi kanye ne-reflow soldering welding:
a: Indlela evamile kakhulu i-solder kagesi, njengokubumba nokulungisa izingxenye ze-electronic.Kulezi zinsuku, abakhiqizi be-LED, ukuze bonge izindleko zabo zokukhiqiza, ikakhulukazi basebenzisa ama-ayina okusoda kagesi omgunyathi futhi angenalutho, okuholela ekuxhumaneni okubi futhi ngezinye izikhathi ukuvuza.Ngesikhathi senqubo yokushisela, lokhu kulingana nokwenza isifunda phakathi kwephuzu lensimbi evuzayo - i-LED edayisiwe - umzimba womuntu - nomhlaba, okusho ukuthi, amandla kagesi aphindwe izikhathi ezingamashumi kuya kwamakhulu kune-voltage etholakalayo. by the ubuhlalu isibani sisetshenziswa LED isibani ubuhlalu, kweso evutha kubo out.
b: Ukukhanya okufile okubangelwa ukushisela endaweni yokushisisa sekube ithuluzi lokukhiqiza elingcono kakhulu lamabhizinisi amaningi ukuze kuhlangatshezwane nezidingo zamaqoqo amancane nama-oda amasampula ngenxa yenani eliqhubekayo lama-oda esampula yesibani.Ngenxa yezinzuzo zezindleko eziphansi zemishini, isakhiwo esilula nokusebenza, isiteji sokushisa sesibe yithuluzi elingcono kakhulu lokukhiqiza, Ngenxa yemvelo yokusetshenziswa (njengenkinga yokungazinzi kwezinga lokushisa ezindaweni ezinamafeni), ubuchwepheshe be-welding operators, kanye ukulawulwa kwejubane lokushisela, kunenkinga enkulu yezibani ezifile.Ukwengeza, kukhona ukufakwa phansi kwemishini yesikhulumi sokufudumeza.
c: I-Reflow soldering ngokuvamile iyindlela yokukhiqiza enokwethenjelwa kakhulu, elungele ukukhiqizwa nokucubungula ngobuningi.Uma ukusebenza kungalungile, kuzodala imiphumela eyingozi kakhulu yokukhanya efile, njengokulungiswa okungenangqondo kwezinga lokushisa, ukungagxili kahle komshini, njll.
2.Indawo yokugcina izinto edala izibani ezifile
Lokhu kuvame ukwenzeka.Uma sivula iphakheji, asizinaki izinyathelo zokuvikela umswakama.Iningi lobuhlalu bezibani emakethe manje selivalwe ngejeli ye-silica.Le nto izomunca amanzi.Uma ubuhlalu besibani buthintekile ngomswakama, ijeli ye-silica izokhula ngokushisa okushisayo ngemuva kokushisela izinga lokushisa eliphezulu.Intambo yegolide, i-chip kanye nobakaki kuzokhubazeka, kubangele ukugudluka nokuphuka kocingo lwegolide, futhi indawo yokukhanya ngeke ikhanyiswe, Ngakho-ke, kunconywa ukugcina ama-LED endaweni eyomile nengena umoya, enezinga lokushisa lokugcina - 40 ℃ -+100 ℃ kanye nomswakama ongaphansi kuka-85%;Kunconywa ukusebenzisa i-LED esimweni sayo sokuqala sokupakisha phakathi nezinyanga ezi-3 ukugwema ukugqwala kubakaki;Ngemva kokuvulwa kwesikhwama sokupakisha se-LED, kufanele sisetshenziswe ngokushesha ngangokunokwenzeka.Ngalesi sikhathi, izinga lokushisa lokugcina lingu-5 ℃ -30 ℃, kanti umswakama ohlobene ungaphansi kuka-60%.
3. Ukuhlanza ngamakhemikhali
Ungasebenzisi uketshezi lwamakhemikhali olungaziwa ukuze uhlanze i-LED, njengoba ingalimaza ingaphezulu le-colloid ye-LED futhi ibangele nokuqhekeka kwe-colloid.Uma kunesidingo, sicela uhlanze nge-alcohol swab endaweni yokushisa yegumbi nendawo enomoya, okungcono kungakapheli umzuzu owodwa wokuqeda umoya.
4. Ukuguquguquka okubangela ukukhanya okufile
Ngenxa yokuguqulwa kwamanye amaphaneli akhanyayo, opharetha bazohlinzwa ngepulasitiki.Njengoba amaphaneli ewohloka, ubuhlalu obukhanyayo obukubo nawo buwohloka ndawonye, buphule ucingo olusagolide futhi bubangele ukuthi izibani zingakhanyi.Kunconywa ukwenza ukuhlinzwa kwepulasitiki ngaphambi kokukhiqizwa kwalolu hlobo lwephaneli.Ukuhlanganiswa nokuphatha isikhathi eside ngesikhathi sokukhiqiza kungase kubangele ukuguquguquka nokuphuka kwentambo yegolide.Futhi, kubangelwa ukupakisha.Ukuze kube lula inqubo yokukhiqiza, amaphaneli ezibani apakishwa ngokungahleliwe.Ngenxa yamandla adonsela phansi, ungqimba olungezansi lobuhlalu bezibani luzokhubazeka futhi kulimaze intambo yegolide.
5. Isakhiwo sokukhipha ukushisa, ukunikezwa kwamandla, nebhodi lesibani akufani
Ngenxa yokungafanelekiukunikezwa kwamandla kagesiukuklama noma ukukhetha, ukunikezwa kwamandla kweqa umkhawulo omkhulu i-LED engamelana nawo (ngaphezu kwamanje, umthelela osheshayo);Isakhiwo sokukhipha ukushisa esingenangqondo sezinto zokukhanyisa singabangela izibani ezifile kanye nokubola kokukhanya ngaphambi kwesikhathi.
6. Isisekelo sefekthri
Kuyadingeka ukuthi kubhekwe ukuthi intambo ephansi yefekthri isesimweni esihle yini
7. Ugesi omile
Ugesi omile ungabangela ukwehluleka kokusebenza kwe-LED, futhi kuyanconywa ukuvimbela i-ESD ekulimazeni i-LED.
A. Ngesikhathi sokuhlolwa nokuhlanganiswa kwe-LED, opharetha kufanele bagqoke amasongo aphikisana ne-static namagilavu aphikisana ne-static.
B. Imishini yokushisela kanye nokuhlola, amatafula okusebenzela, ama-racks, njll. kufanele kusekelwe phansi.
C. Sebenzisa i-ion blower ukuze ukhiphe ugesi omile okhiqizwa ukungqubuzana phakathi nokugcinwa nokuhlanganisa i-LED.
D. Ibhokisi lempahla yokufaka i-LED lamukela ibhokisi lempahla elwa ne-static, futhi isikhwama sokupakisha samukela isikhwama se-electrostatic.
E. Ungabi nesimo sengqondo esishintshashintshayo futhi uthinte i-LED ngokunganaki.
Izenzakalo ezingavamile ukuthi ukulimala kwe-LED okubangelwa i-ESD kuhlanganisa:
A. Ukuvuza okubuyela emuva kungase kubangele ukuncipha kokukhanya ezimweni ezincane, futhi ukukhanya kungase kungakhanyi ezimeni ezinzima.
B. Inani le-voltage eya phambili liyehla.I-LED ayikwazi ukukhipha ukukhanya uma iqhutshwa amandla aphansi.
C. Ukushisela okubi kwenza isibani singakhanyi.
