Izibane ezifileyo ze-LED, abathengi abanje ngeenkampani zokupakisha, iimveliso ezigqityiweyo ezisezantsi ukuya kwiiyunithi kunye nabantu abasetyenziselwa ukusetyenziswa banokudibana nayo. Isizathu kukuba kukho iintlobo ezimbini zeemeko: Okokuqala, ukuvuza kwangoku kwe-LED kukhulu kakhulu ukwenza ilahleko yeqhina le-PN, ukuze izibane ze-LED zingabonakali, kwaye uhlobo lwemeko ngokubanzi aluchaphazeli umsebenzi ezinye izibane ze-LED; okwesibini, i-LED, i-LED, i-LED Inkokeli yokudibanisa yangaphakathi yokukhanya iphukile ukwenza isibane esifileyo se-LED ngaphandle kokudlula ngoku. Uhlobo lwemeko luya kuchaphazela umsebenzi jikelele wezinye izibane ze-LED. V —I-2.2V, i-blue-green and white LED i-voltage yomsebenzi we-2.8 —3.2V), idityaniswe ngokubanzi ngomtya kunye nokudibanisa ukwenza amandla ombane ohlukeneyo omsebenzi. Okukhona izibane ze-LED ziqhagamshelwe, kokukhona ifuthe elikhulu. Ukukhanya kwe-zero-string ye-LED akukhanyi, kunokubonwa ukuba imeko inzima kakhulu kunohlobo lokuqala lwemeko. Izibane ezifileyo ze-LED ziGuan Jian, ezichaphazela ubungakanani bemveliso kunye nokuthembeka. Indlela yokunciphisa kunye nokuphelisa izibane ezifileyo kunye nokunyusa umthamo wemveliso kunye nokuthembeka ngumba obalulekileyo ekufuneka ujongwe ngokutywinwa kunye nokusebenzisa amashishini. Masenze uhlalutyo kunye neengxoxo malunga nokwenziwa kwezibane ezifileyo. 1. Umonakalo we-electrostatic kwi-chip ye-LED yonakele ukwenza iqhina le-PN le-chip ye-LED linyamalale, ukuvuza kwangoku kuyacinywa, kwaye kuba luhlobo lokumelana. Ngumtyholi oyingozi kakhulu. Amashumi ezigidi zeerandi zelahleko yezoqoqosho. Ke ngoko, icandelo lombane le-anti-line electronic component ngumsebenzi obaluleke kakhulu kushishino lombane. Ungayithathi lula ukupakishwa kwe-LED kunye neenkampani zokubonisa i-LED. Ukuba kukho ingxaki kuyo nayiphi na ikhonkco, iya kubangela umonakalo kwi-LED, eya kubangela ukuba ukusebenza kwe-LED kuhla. Siyazi ukuba umzimba womntu (ESD) unokufikelela amawaka amathathu e-volt ekhohlo ekhohlo, kwaye iinyawo zingaphula i-chip ye-LED ngomonakalo. Kukupakisha imigca yokuvelisa kwi-LED. Ingaba ukuchasana komhlaba kwezixhobo ezahlukeneyo kunokuhlangabezana neemfuno. Kwakhona ibaluleke kakhulu. Ngokubanzi, ukumelana komhlaba kuyafuneka Kwi-4 ohms, ukumelana komhlaba akufuneki ukufikelela ku-2 ohm. Umonakalo we-LED womzimba womntu nawo mkhulu kakhulu. Xa usebenza, unxibe iiyunifomu ezichasene ne-static, kunye nomsesane omileyo wombane, umsesane omileyo we-electrostatic ngumboniso ombi, kwaye akukho siphumo silungileyo kujikelezo lwe-electrostatic yeringi ye-electrostatic. Ukuba awusebenzisi olu hlobo lwemveliso, ukuba abasebenzi baphula iinkqubo zokusebenza, kufuneka bafumane isilumkiso esikhulu, kwaye kwangaxeshanye, ikwakhuthaza ukusetyenziswa kwabanye. Ungakanani umzimba womntu onombane ongatshintshiyo, iimpahla ezahlukeneyo zelaphu ezinxitywa ngabantu, kunye nomthamo womntu ngamnye, ekwindla nasebusika ebusuku, kunzima ukubona ukukhutshwa phakathi kweengubo. Intloko. Ixabiso le-ESD ye-silicon-based base chip yi-volts eyi-1100 kuphela, kwaye ixabiso le-ESD ye-chip ye-sapphire iphantsi, nje 500 —Iivolts ezingama-600. I-chip enhle okanye i-LED, ukuba siyithatha ngezandla zethu (umzimba awuthathi nayiphi na imilinganiselo yokukhusela), iziphumo zinokuthi zicinge ukuba i-chip okanye i-LED iya konakaliswa ngamaqondo ahlukeneyo. Isandla sihle kangangokuba sihle kangangokuba sisibetho sombane ongatshintshiyo. Ukuba ishishini lokupakisha alisebenzi ngokungqongqo ngokuhambelana nemimiselo yomhlaba, yinkampani ngokwayo eya kunciphisa izinga lokufaneleka kwemveliso kwaye inciphise ukunyaniseka kwezoqoqosho kwishishini. Ukuba izixhobo kunye nabasebenzi abasebenzisa ii-LED azisekelwanga Akunakuphepheka. Ngokuhambelana neemfuno ze-LED standard manual, i-colloid ye-LED yomgama okhokelayo ayikho ngaphantsi 3 —I-5 mm, ukugoba okanye ukuwela, kodwa uninzi lweenkampani aziyenzi oko, kodwa kuphela ubukhulu bebhodi yePCB (≤2 mm) i-welding engathanga ngqo, eya kubangela umonakalo okanye umonakalo kwii-LED. Ngenxa yokuba ukushisa okugqithisileyo kwe-welding kuya kuchaphazela i-chip, kuya kuphazamisa iimpawu ze-chip kunye nokunciphisa ukukhanya kokukhanya, ukwenzela ukuba le nto ingaqhelekanga. Akukho shishini lincinci lisebenzisa i-welding manual, usebenzisa i-40 wattipaton soldering iron, ubushushu be-welding ayikwazi ukulawulwa, kunye nobushushu bentsimbi ye-solder. 300 —Ngaphezulu kwe-400 C, ubushushu obuphezulu kakhulu be-welding buya kwenza izibane ezifileyo. I-LED ekhokelayo iphezulu ngamaxesha amaninzi kune-coefficient yokuvuvukala kwi-150 C kwiqondo lokushisa eliphezulu. Ingqele ecutha indawo ye-welding ivuleke, yenze into yesibane esifileyo. 2. Isizathu sokwenzeka kwesiganeko sesibane kwi-welding yangaphakathi yokudibanisa izibane ze-LeD. 2.1 Uhlalutyo lwenzeka yezibane ezifileyo 2.1 Inkqubo yokuveliswa kweshishini lokupakisha ayigqitywanga, kwaye indlela yokuhlola ibuyele ngasemva. Uluhlu lokuvala lwenziwe ngobhedu okanye izinto zetsimbi zetsimbi ngokubumba okuchanekileyo. Ngenxa yokuba izinto zobhedu zibiza kakhulu, ixabiso liphezulu ngokwendalo. Ngenxa yeemarike ezinobunzima, izinto ezichaphazelekayo zichaphazelekayo. Intsimbi izisa ii-LEDs zokutyibilika. Ukuvalwa kwentsimbi yentsimbi kufuneka kube yisilivere-ifakwe. I-plating yesilivere ayinayo imiphumo emibini. Enye kukuthintela i-moxibustion kunye nomhlwa. Enye kukuququzelela ukuwelda. Inxulumene nobomi be-LED. Ngaphambi kwe-electroplating, ukucubungula kufuneka kuqhutywe ngokungqongqo ngokuhambelana nemithetho, kwaye inkqubo yokususa, ukukhutshwa kweoli, kunye ne-phosphorus kufuneka ibe yinto engapheliyo. , Ukwaleka kukhulu kakhulu kwaye ixabiso liphezulu kakhulu, lincinci kakhulu ukuchaphazela inani. Ngenxa yokuba iinkampani zokupakisha ze-LED eziqhelekileyo azikwazi ukujonga ubungakanani be-electroplating, inika amanye amashishini e-electroplating ngaphandle kwezithuba zokunciphisa umaleko wesilivere we-electroplating, ukunciphisa ingeniso yeendleko. Indlela yokuvavanya ilahlekile, kwaye akukho sixhobo esinobunzima kunye nokukhawuleza kwe-straton plating layer. Ndibonile ukuba ndibone iinyanga ezimbalwa kwi-warehouse kwaye ndinomhlwa emva kweenyanga ezimbalwa. Iimveliso ezenziwe ngomqolo onjalo wokuvala ngokuqinisekileyo azikude, ungatsho 3 —Iiyure ezingama-50,000, iiyure ezingama-10,000 ziyingxaki. Isizathu silula kakhulu minyaka le ngaphandle kwexesha lexesha. Imozulu kunye nokufuma komoya emoyeni kuphezulu, kwaye kunzima ukwenza iindawo ezahlukeneyo zetsimbi ye-electroplating. Nokuba i-LED ehlanganisiweyo iya kuba yincinci kakhulu kwaye i-silver-plated layer incinci kakhulu, kwaye i-welding joints iya kuthathwa ukuze yenze into yesibane esifileyo. Okokuthi, izibane esiye sadibana nazo azivulwanga, kodwa ngokwenene, iimbumba ze-solder zangaphakathi zithathwa kwi-shelf. 2.2 Inkqubo nganye engaphandle kwenkqubo yokupakishwa mayenziwe ngokungqinelana nelahleko. Isizathu sokungakhathali kwayo nayiphi na ikhonkco kukwenza isibane esifileyo. Iglu iya kubuyela kwi-chip pad yegolide ukwenza isiphaluka esifutshane, kwaye i-chip iya kuba yinto encinci. Kukwanjalo nangetshungama yokugquma itshiphu edityanisiweyo. Ukuba uodola intlaka ngakumbi insulating, uya kubuyela iphedi yegolide chip ukwenza isiqhamo welding virtual ngexesha welding. Kukho iitshiphusi ezimbalwa kwaye azikwazi ukuqina, ngoko ke umbhobho kufuneka ulungile. Inkqubo ye-welding nayo ibalulekile. Ulungelelwaniso loxinzelelo, ixesha, ubushushu, kunye namandla omatshini wokuwelda ngocingo lwegolide kufuneka lulunge kanye. Ngaphandle kwexesha elimiselweyo, ezinye iiparamitha ezintathu ziyakwazi ukulungelelanisa. I-Dacong inzima ukutyumza i-chip, incinci kakhulu, kunzima ukuyidibanisa. Ubushushu be-welding ngokubanzi ngama-280 C. Ukulungiswa kwamandla kubhekisela kwi-ultrasonic power conditioning. Inkulu kakhulu kwaye incinci kakhulu. Izinto ezilungileyo, uvavanyo kunye nemilinganiselo yovavanyo lwentwasahlobo ≥6 yeegram, ezifanelekileyo. Unyaka ngamnye, iiparameters zomshini wegolide we-welding yebhola zichongiwe kwaye zibalwe ukuze kuqinisekiswe ukuba iiparitha ze-welding zikwifom engcono kakhulu. Ukongezelela, i-arc yomgca we-welding ayifuni. Umphakamo we-arc we-welding point chip yi-1.5-2 ye-chips ubukhulu, kwaye ukuphakama kwe-arc ye-welding joint chip yi-2-3 ye-chips. Umphakamo we-arc uphantsi kakhulu ukuba wenze isibane esifileyo xa uwelding. 3. Indlela yokuchonga isibane se-welding esifileyo siya kufudumeza isibane se-LED esingaguqukiyo kunye nekhaphukhaphu ukufudumeza isikhokelo se-LED ukuya kwi-200-300 C, sisuse isibane, kwaye siqhagamshele i-LED ngebhetri ye-volt eyi-3 kunye ne-electrode engalunganga. Ukukhanya, kodwa ukukhanya kwe-LED kuncitshisiwe ukusuka ekukhanyeni ukuya kuthi ga kwiqondo lokushisa lokutshabalalisa, emva koko kubonisa ukuba ukukhanya kwe-LED yi-welding ebonakalayo. Isizathu sokufudumala sinokukhanya kukusetyenziswa kwentsimbi ye-thermal contraction kunye ne-contraction. Inkokeli ye-LED iyandiswa kwaye yandiswe kumalungu angaphakathi e-solder xa kushushu. Ukunciphisa umzobo kwifom yeqondo lokushisa eliqhelekileyo, ukuqhawula indawo ye-solder yangaphakathi, ukukhanya kwe-LED akukhanyi, uhlobo lwendlela oluzama ngokuphindaphindiweyo lungokomoya. Ukuwelda isibane esine-welded ezimbini kolo hlobo lwe-welding ebonakalayo kumgca wesinyithi, ofakwe nge-asidi yesulfuric engqindilili ukunyibilikisa i-colloid yangaphandle ye-LED, kwaye i-colloid iyanyibilika kwaye isuswe. Unokufumana ingxaki yokuba i-welding yokuqala okanye i-welding ezimbini. Ngaba iparameter yegolide ye-silika ye-welding machine ayilungile, okanye ezinye izizathu zokuphucula iindlela kunye neenkqubo. Abasebenzisi abasebenzisa iimveliso ze-LED baya kuphinda bahlangane nesiganeko sezibane ezifileyo, oko kukuthi, emva kokuba iimveliso ze-LED zisetyenziselwa ixesha elithile, isiganeko sezibane ezifileyo zenzeka. Akukho zizathu zibini zezibane ezifileyo. Akukho ngxaki ngenani le-electroplating, kwaye ukuvuza kwangoku kwe-chip ye-LED kuya kwenza ukukhanya kwe-LED akuyi kukhanyisa. Ngoku ukuba iimveliso ezininzi ze-LED zikhuselwe ngokungafaki ukukhuselwa kwe-anti-electrostatic ukwenzela ukunciphisa iindleko, ngoko kunzima ukuba nengqiqo njenge-chip yomonakalo we-static. Kunzima ukubonisa umgca wokubonelela ngokukhanya kwiintsuku zemvula njengombane ophezulu we-electrostatic, kunye ne-peak pulse yokupakishwa komgca wombane, oya kubangela ukuba iimveliso ze-LED zonakaliswe kwiidigri ezahlukeneyo. Akukho zizathu zininzi zezibane zokufa. Ayinakudweliswa nganye nganye. Ukususela ekupakishweni, ukusetyenziswa, kunye nokusetyenziswa kwezixhumanisi ezahlukeneyo, akunakwenzeka ukuba kubonakale izibane ezifileyo. Indlela yokwandisa inani leemveliso ze-LED kukuba ishishini lokudiliza kunye nokusetyenziswa kweshishini kufuneka kuqatshelwe kakhulu. Kwaye umba wophando lophando, ukusuka kwiitshiphusi kunye nokukhethwa kwe-rack, ukuya kwinkqubo yokupakishwa kwe-LED yero, ngokwenkqubo yobungakanani be-ISO2000. Ngethuba nje imveliso ye-LED inokunyuswa ngokubanzi, ingaba ubomi obude, iphezulu kwaye inokwethenjelwa. Ngokubhekiselele kwiisekethe ezisetyenziswayo, ukukhetha ukuxhatshazwa kwe-voltage-sensitive kunye ne-PPTC yokuphucula isiphaluka sokukhusela, ukongeza inani elihambelanayo leendlela ezihambelanayo, kwaye usebenzise ukuguqulwa kwangoku ngokuqhubekayo. Ukucima ukukhuselwa kweqondo lokushisa ngumlinganiselo ongavumelekanga wokuphucula ukuthembeka kweemveliso ze-LED.
