B) N'ihi na mgbawa LED ka dị na obere spacing (ihe dị ka 0.1mm) mgbe emechara mgbawa LED, ọ naghị akwado ọrụ nke post-process. Anyị na-agbasa ihe nkiri nke mgbawa nrapado site na iji igwe mgbasawanye. Ọ bụ oghere nke mgbawa LED na-agbatị ihe dịka 0.6mm. Enwere ike iji aka gbasaa ya, mana ọ dị mfe ịkpata nsogbu ọjọọ dị ka mgbawa mkpofu. C) Gluo ọlaọcha ma ọ bụ gluu na-ekpo ọkụ na ọnọdụ kwekọrọ na gluu n'ọnọdụ kwekọrọ na bracket LED. (Maka GAAS na SIC conductive substrates, red light, yellow light, yellow-green chip with back electrode na azụ, jiri ọlaọcha chịngọm. Maka ọkụ na-acha anụnụ anụnụ na mgbawa LED nke sapphire insulating base, jiri gluu mkpuchi dozie mgbawa ahụ. ) Ihe isi ike nke usoro ahụ na-adabere n'ịchịkwa ọnụ ọgụgụ nke adhesion, na e nwere nkọwa zuru ezu usoro chọrọ na elu nke elu colloid na isi ihe dị na ya. . N'ihi na gluu ọlaọcha na ihe mkpuchi mkpuchi nwere ihe siri ike chọrọ na nchekwa na ojiji, ịkpọte, mkpali, na iji oge nke gluu ọlaọcha bụ ihe niile a ga-aṅa ntị na ya. D) N'adịghị ka nkwadebe na isi replenishment, gluu na-akwadebe bụ itinye ọlaọcha gluu na LED azụ electrode na nkwadebe igwe, wee wụnye LED na ọlaọcha gluu na azụ na ikanam bracket. Ịdị irè nke nkwadebe dị elu karịa nke gluu, ma ọ bụghị ngwaahịa niile na-emetụta usoro nkwadebe. E) Spines nke ejiri aka mee Tọọ mgbasawanye nke mgbawa LED (nkwadebe ma ọ bụ gel a na-akwụghị ụgwọ) na ntinye nke okpokoro ogwu. A na-etinye ihe nkwado LED n'okpuru nkwụnye ahụ. N'okpuru microscope, a na-adụpu mgbawa LED n'ọnọdụ kwekọrọ na agịga n'okpuru microscope. E jiri ya tụnyere ntinye akpaaka nke aka -cranked, ọ nwere otu uru ma e jiri ya tụnyere ya, nke dị mma maka ịgbanwe ibe dị iche iche n'oge ọ bụla.
