Loaʻa nā SMD i lalo a me COB alakaʻi i lalo i ka Lediant. ʻIke ʻoe i ka ʻokoʻa ma waena o lākou? E haʻi aku wau iā ʻoe.
He aha ka SMD? ʻO ia hoʻi nā mea i kau ʻia ma luna. ʻO ka hale hana hoʻopihapiha LED me ka hoʻohana ʻana i ke kaʻina SMD e hoʻoponopono i ka pahu pahu ma ka bracket, e hoʻopili uila i nā mea ʻelua me nā uea gula, a hope loa e pale iā ia me ka resin epoxy. Hoʻohana ʻo SMD i ka ʻenehana mauna ʻili (SMT), kahi kiʻekiʻe o ka automation. a loaʻa iā ia nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, nui ka hoʻopuehu ʻana, maikaʻi ka like ʻana o ka luminous, a me ka hilinaʻi kiʻekiʻe.
He aha ka COB? ʻO ia hoʻi, chip ma luna o ka moku. ʻAʻole like me SMD, nāna e kūʻai aku i nā pahu kukui i ka PCB, ua uhi mua ke kaʻina COB i ka wahi hoʻokomo o ka chip silicon me ka thermally conductive epoxy resin (silver-doped epoxy resin) ma ka ʻili o ka substrate. A laila hoʻopaʻa ʻia ka chip LED i ka substrate interconnection me ka conductive a i ʻole ka hoʻoheheʻe ʻole ʻia ma o ka adhesive a i ʻole solder, a ma hope o ka pilina uila ma waena o ka chip a me ka PCB e ʻike ʻia e ka uea (uaea gula).
