He aha te SMT?
Ko te SMT, arā, te hangarau whakamau mata, he hangarau e whakamau tika ana i ngā wāhanga hiko ki te mata o te papa ara iahiko tā (PCB). Kei te piki haere te rongonui o tēnei huarahi nā ōna painga maha, tae atu ki te kaha ki te whakamahi i ngā wāhanga iti ake, te whakatutuki i te kiato wāhanga teitei ake, me te whakapai ake i te whai huatanga o te hanga.
He aha te SMD?
Ko te SMD, e pā ana ki te Surface Mount Device, ko ngā wāhanga hiko kua hangaia mō te whakamahi me te SMT. Kua hangaia ēnei wāhanga hei whakairi tika ki te mata PCB, ā, kāore e hiahiatia he whakairinga mā roto i te kōhao tuku iho.
Ko ngā tauira o ngā wāhanga SMD ko ngā ātete, ngā pūnga, ngā taio, ngā transistor, me ngā ara iahiko whakauru (IC). Nā tōna rahi kiato ka taea te whakanui ake i te kiato o ngā wāhanga i runga i te papa ara iahiko, ka hua ake he mahi nui ake i roto i te tapuwae iti.
He aha te rerekētanga i waenga i te SMT me te SMD?
He mea nui kia mārama ki ngā rerekētanga motuhake i waenga i te hangarau whakairi mata (SMT) me ngā taputapu whakairi mata (SMD). Ahakoa e pā ana, he rerekē ngā āhuatanga o te hanga hikohiko e uru ana ki roto. Anei ētahi o ngā rerekētanga matua i waenga i te SMT me te SMD:
Whakarāpopototanga
Ahakoa he rerekē ngā ariā o te SMT me te SMD, he tata tonu te whanaungatanga. Ko te SMT e pā ana ki te tukanga hanga, ko te SMD ia e pā ana ki te momo wāhanga e whakamahia ana i roto i te tukanga. Mā te whakakotahi i te SMT me te SMD, ka taea e ngā kaihanga te whakaputa i ngā taputapu hiko iti ake, kiato ake me te mahi whakarei ake. Kua hurihia e tēnei hangarau te umanga hiko, ka taea ai ngā waea atamai huatau, ngā rorohiko mahi teitei me ngā taputapu hauora matatau, me ētahi atu auahatanga.
Anei te rārangi o tā mātou Motuka Whakarere SMD:
