Kei te waatea te rama a SMD me te COB i Lediant. Kei te mohio koe ki te rereketanga i waenga i a raatau? Kia korero ahau ki a koe.
He aha te SMD? Ko te tikanga o nga taputapu kua eke ki runga. Ko te wheketere takai LED e whakamahi ana i te tukanga SMD ka whakatika i te maramara kore i runga i te awhi, ka hono hiko te rua ki nga waea koura, ka mutu ka tiakina ki te epoxy resin. Ka whakamahia e te SMD te hangarau o te mata (SMT), he ahua teitei o te automation, a he pai nga painga o te rahi iti, te koki marara nui, te riterite maramara pai, me te tino pono.
He aha te COB? Ko te tikanga he maramara i runga i te papa. Kaore i rite ki te SMD, nana i hoko nga pirepire rama ki te PCB, ko te tukanga COB i te tuatahi ka hipokina te waahi tuunga o te maramara silicon ki te kapia epoxy epoxy (he kapia epoxy-doped hiriwa) i runga i te mata o te tïpako. Na ka piri te maramara arahina ki te tïpako hononga ki conductive kāpia kore-conductive ranei i roto i te whakapiri konuhono ranei, me te mutunga te hononga hiko i waenganui i te maramara me te PCB te ite i te waea (waea koura) here.
