Blackening nkeIhuenyo ngosi LEDbụ ihe a na-ahụkarị.Taa, ka anyị leba anya n'ọtụtụ isi ihe kpatara oji ji agbaji.
1. Sulfurization, chlorination, na bromination
Ihe mkpuchi ọlaọcha na akara ngosi ngosi LED ga-emepụta sulfide ọlaọcha mgbe ọ na-abanye na kọntaktị na sọlfọ nwere gas, na mgbe ọ na-abanye na kọntaktị na acidic nitrogen nke nwere chlorine na bromine gas, ọ ga-emepụta halide ọlaọcha nke photosensitive, nke ga-eme ka ọ pụta ìhè. isi iyi ọkụ na-atụgharị oji wee daa.Sulfur / chlorine / bromination nke isi iyi ọkụ nwere ike ime na ọkwa ọ bụla nke mmepụta, nchekwa, ịka nká, na ojiji nke isi iyi ọkụ LED na oriọna.Mgbe achọpụtara ya na sọlfọ / chlorine / bromination n'ihi na-agbaji isi iyi ọkụ, onye ahịa kwesịrị ịhọrọ otu atụmatụ iwepụ sọlfọ nke dabeere na ogbo ebe sọlfọ / chlorine / bromination na-eme.Ka ọ dị ugbu a, ọrụ nchọpụta sulfur/chlorine/bromine nke Jinjian hibere gụnyere: sọlfọ sulfur/chlorine/bromine (gụnyere ọkụ arụnyere arụnyere), sọlfọ sọlfọ/chlorine/bromine (ewezuga ọkọnọ ike mpụga), sọlfọ ọkụ/chlorine/ bromine, ihe inyeaka sọlfọ / chlorine / bromine, nkwakọ ihe ogbako sọlfọ / chlorine / bromine, sọlfọ ọkụ ọkụ sulfur / chlorine / bromine, na reflow soldering ogbako sọlfọ / chlorine / bromine.N'ihi eziokwu ahụ bụ na gas nwere sọlfọ, chlorine na bromine nwere ike ịbanye n'ime ime ọkụ site na oghere dị na silicone ma ọ bụ brackets, Jinjian ewepụtala atụmatụ nyocha ikuku iji nyere ndị ahịa aka imeziwanye ihe ha chọrọ maka ihe ọkụ ọkụ.
2. Oxidation
Ọlaọcha na-eme ngwa ngwa na ikuku oxygen na oke okpomọkụ na gburugburu iru mmiri, na-emepụta oxide ọlaọcha ojii.Mgbe ekwenyechara na ihe kpatara blackening nke ìhè bụ oxidation nke silver plating oyi akwa, Jin Jian ga-atụ aro na ndị ahịa ga-eduzi ikuku tightness elele na ìhè isi iyi na oriọna iji kpochapụ ụzọ nke mmiri infiltration.
3. Carbonization
Dabere na ahụmịhe, ntụpọ ihe na isi akụrụngwa isii nke isi iyi ọkụ LED (chips, brackets, gluu siri ike, eriri njikọ, fluorescent ntụ ntụ, na gluu nkwakọ ngwaahịa) na nhazi ntụpọ na usoro nkwakọ ngwaahịa atọ (kristal siri ike, wiring, na gluing) niile nwere ike iduga oke okpomoku dị elu na isi iyi ọkụ, na-eme ka agbaji mpaghara ma ọ bụ n'ozuzu ya na carbonization nke isi iyi ọkụ.Ngwunye ọkụ na-enweghị ezi uche nke oriọna LED, obere ihe na-ekpo ọkụ ọkụ nke ihe na-ekpo ọkụ ọkụ, ike na-enweghị ezi uche na-enweghị isi, na ọtụtụ ntụpọ reflow na-agbapụta nwekwara ike ime ka carbonization nke ìhè ọkụ.Ya mere, mgbe Jinjian preliminarily kwadoro na ihe kpatara blackening nke ìhè bụ carbonization, ọ ga-atụ aro na ndị ahịa na-eso LED ìhè isi iyi ma ọ bụ oriọna ọdịda analysis ụzọ, dissect ìhè isi iyi / oriọna, na-achọpụta isi iyi nke ntụpọ ma ọ bụ. elu thermal iguzogide.
4. Chemical enweghị ndakọrịta
Ojiji nke ọkụ ọkụ LED nwekwara ike bute ya site na mmetọ kemịkalụ, ihe na-agbaji agbaji a na-emekarị na oriọna agbachiri na-enwe obere ikuku ma ọ bụ enweghị.
Mgbe anyị zutere ọnọdụ ebe ihuenyo ngosi LED na-atụgharị oji, anyị nwere ike nyochaa ihe kpatara otu otu ma mee mgbanwe.
