1. Welding mhando
Kazhinji, welding inogona kukamurwa kuita mhando nhatu: yemagetsi solder iron welding, yekudziya papuratifomu welding uye reflow soldering welding:
a: Nzira yakajairika ndeyekushongedza kwemagetsi, zvakadai sekugadzira uye kugadzirisa zvikamu zvemagetsi.Mazuva ano, vagadziri ve LED, kuitira kuchengetedza mari yavo yekugadzira, vanonyanya kushandisa simbi dzemagetsi dzekunyepedzera uye dzisina kusimba, zvichikonzera kusabatana kwakashata uye dzimwe nguva kudonha.Munguva yewelding process, izvi zvakaenzana nekugadzira denderedzwa pakati peinodonhedza solder iron tip - iyo soldered LED - muviri wemunhu - uye pasi, Kureva, voltage iyo ine makumi kusvika kumazana enguva yakakura kupfuura voltage inotakurwa. nemarambi mabheji anoiswa kune mabheji emwenje e LED, achiapisa pakarepo.
b: Chiedza chakafa chinokonzerwa newelding papuratifomu yekudziya chave chishandiso chakanakisa chekugadzira kumabhizinesi mazhinji kuitira kuti isangane nezvinodiwa zvemabheti madiki uye maodha emuenzaniso nekuda kwenhamba inoenderera yemwenje sampuli yemirairo.Nekuda kwemabhenefiti emutengo wakaderera wemidziyo, chimiro chakareruka uye kushanda, chikuva chekudziya chave chishandiso chakanakisa chekugadzira, Nekuda kwenzvimbo yekushandisa (senge dambudziko rekusagadzikana kwekushisa munzvimbo dzine mafeni), kugona kwevanoshandisa welding, uye kudzora kumhanya welding, kune dambudziko rakakura remwenje akafa.Pamusoro pezvo, pane kugadzika kwemidziyo yekudziya yepuratifomu.
c: Reflow soldering kazhinji ndiyo yakavimbika nzira yekugadzira, iyo yakakodzera kugadzirwa kwakawanda uye kugadzirisa.Kana kuvhiya kwacho kusina kunaka, kunokonzeresa zvakakomba mhedzisiro yemwenje yakafa, senge isingaite tembiricha gadziriso, isina kusimba muchina, nezvimwe.
2.Storage environment inokonzera magetsi akafa
Izvi zvinowanzoitika.Patinovhura pasuru, isu haticherechedze matanho ekudzivirira hunyoro.Mazhinji emarambi emarambi pamusika zvino akavharwa nesilica gel.Nyaya iyi inotora mvura.Kana marambi akabatwa nehunyoro, iyo silica gel inozowedzera kupisa mushure mekushisa kwekushisa kwepamusoro.Iyo tambo yegoridhe, chip uye bracket ichave yakaremara, zvichikonzera kutama uye kuputsika kwewaya yegoridhe, uye nzvimbo yechiedza haizovheneke, Naizvozvo, zvinokurudzirwa kuchengetedza ma LED munzvimbo yakaoma uye ine mhepo, ine tembiricha yekuchengetedza - 40 ℃ -+100 ℃ uye hunyoro husingasviki 85%;Inokurudzirwa kushandisa iyo LED mune yayo yekutanga yekurongedza mamiriro mukati memwedzi ye3 kudzivirira ngura yebhureki;Mushure mekunge bhegi rekurongedza re LED ravhurwa, rinofanira kushandiswa kumusoro nekukurumidza sezvinobvira.Panguva ino, tembiricha yekuchengetera ndeye 5 ℃ -30 ℃, uye hunyoro huri pasi pe60%.
3. Kucheneswa kwemakemikari
Usashandise zvinwiwa zvemakemikari zvisingazivikanwi kuchenesa LED, sezvo inogona kukuvadza pamusoro pe LED colloid uye kunyange kukonzera colloid kutsemuka.Kana zvichidikanwa, ndokumbira uchenese nedoro swab mukamuri tembiricha uye mhepo inofefetera, zviri nani mukati meminiti imwe yekupedzwa kwemhepo.
4. Deformation inokonzera chiedza chakafa
Nekuda kwekuchinja kwemamwe mapaneru emwenje, vashandisi vanozovhiyiwa epurasitiki.Sezvo mapaneru akanganisa, mabhero emwenje paari anochinjawo pamwechete, achityora waya yegoridhe uye kuita kuti mwenje usavheneke.Inokurudzirwa kuita kuvhiyiwa kwepurasitiki kusati kwagadzirwa kwemhando iyi yepaneti.Kuungana kwenguva refu uye kubata panguva yekugadzira kunogona kukonzera deformation uye kutsemuka kwewaya yegoridhe.Uyezve, inokonzerwa ne stacking.Kuti ufambise maitiro ekugadzira, mapaneru emwenje anoiswa zvisina tsarukano.Nekuda kwesimba rinokwevera zvinhu pasi, chidimbu chepasi chemarambi chichakanganiswa uye chinokanganisa waya yegoridhe.
5. Chimiro chekupisa kupisa, magetsi, uye bhodhi remwenje hazvifananidzi
Nekuda kwekusafaniramagetsidhizaini kana kusarudzwa, iyo magetsi inodarika iyo yakanyanya muganho iyo LED inogona kumira (pamusoro pezvino, pakarepo kukanganisa);Izvo zvisinganzwisisike zvekupisa kupisa chimiro chezvigadziriso zvekuvhenekesa zvinogona kukonzera mwenje wakafa uye kupera kwechiedza nguva isati yakwana.
6. Factory grounding
Izvo zvinodiwa kuti utarise kana iyo yese yekugadzika waya yefekitori iri mumamiriro akanaka
7. Simba remagetsi
Simba remagetsi rinogona kukonzera kutadza kushanda kwe LED, uye zvinokurudzirwa kudzivirira ESD kubva mukukuvadza LED.
A. Panguva yekuedza nekubatanidza LED, vashandi vanofanira kupfeka anti-static bracelets uye anti-static girovhosi.
B. Welding uye midziyo yekuedza, matafura ekushanda, masheji ekuchengetedza, nezvimwewo zvinofanira kunge zvakadzika pasi.
C. Shandisa ion blower kubvisa static magetsi anogadzirwa ne friction panguva yekuchengetedza LED uye gungano.
D. Bhokisi rezvinhu zvekuisa LED rinotora anti-static material box, uye bhegi rekutakura rinotora electrostatic bag.
E. Usave nemafungiro asina kunaka uye kubata LED zvakasununguka.
Izvo zvisina kujairika izvo kukuvara kwe LED kunokonzerwa neESD kunosanganisira:
A. Reverse leakage inogona kukonzera kudzikira kwekupenya muzviitiko zvinyoro, uye mwenje unogona kusabatika muzviitiko zvakanyanya.
B. Iyo yemberi voltage kukosha inoderera.LED haigone kuburitsa mwenje kana ichityairwa neyakaderera ikozvino.
C. Kusakwenenzverwa kwaita kuti mwenje usavheneke.
