He rerekē ngā whakaritenga mō ngā pūnga hiko i roto i ngā taputapu hiko tino tika, nā te mea e hiahia ana ia āhuatanga tono ki ngā āhuatanga hiko me te pono motuhake. Ko ngā pūnga hiko, hei wāhanga matua kore mahi, he mahi nui tā rātou ki te rokiroki pūngao, ki te tātari tohu, ki te whakaū i te ngaohiko, me te whakahaere wā. Hei whakarite i te mahi tino pai me te roa o te ora o ngā pūnaha hiko, he mea nui kia whiriwhiria ngā pūnga hiko i runga i te taurite tawhā taipitopito me te tātari āhuatanga tono.
I roto i ngā taputapu hiko tere-teitei, kiato-nui o ēnei rā, kua noho ngā taputapu whakairi-mata (SMD) hei tūāpapa mō te hoahoa ara iahiko hou. Haunga ngā pūnga hiko, ngā ātete, ngā inductors, ngā tātari EMI, me ngā thermistors, ka hangaia te pūnaha wāhanga kore mahi nui e whakarite ana i te pumau, te mahi ārai-whakararuraru, me te roa o te mau i roto i ngā tono ahumahi, motuka, me te semiconductor.
Ko ngā ātete maramara ngā wāhanga e whakamahia whānuitia ana, e whakarato ana i te herenga iahiko tika, te wehenga ngaohiko, me te whakaiti tohu. Ko ngā ātete kiriata angiangi tino tika e tuku ana i te iti o te manawanui (tae atu ki te ±0.1%), te tauwehenga pāmahana iti (TCR), me te pumau pai rawa atu, e pai ai mō te ine, te taputapu, me ngā ara iahiko whakawhitiwhiti kōrero. Ko ngā ātete mana, he rerekē, e tautoko ana i te tohatoha kaha teitei, ā, e whakamahia whānuitia ana i roto i te whakahaere mana, te whakahaere motuka, me ngā pūnaha taraiwa ahumahi.
He mea nui ngā takahuri maramara me ngā takahuri hiko ki te rokiroki pūngao, te tātari, me te hurihanga DC-DC. Mā te iti o te ātete DC (DCR) me te nui o te iahiko mātotoru, ka whakaitihia te ngaronga hiko me te whakapai ake i te pai o te hurihanga. Ka tautokohia e ngā takahuri auau-teitei ngā ara iahiko tohu auau-reo irirangi (RF) me te tere-teitei, me te pupuri i te pono o te tohu me te whakaiti i te pokanoa hikohiko.
Ko ngā wāhanga pehi EMI, tae atu ki ngā pītiti maramara, ngā kōkō aratau-noa, me ngā tātari pā-iti, ka tiaki i ngā ara iahiko tairongo mai i te haruru o waho me te pokanoa o roto. He mea nui rawa atu ēnei wāhanga i roto i ngā takai haurua-ira, ngā hikohiko motuka, me ngā taputapu atamai, e pā tika ana te tuku tohu pumau ki te mahi me te haumaru o te hua.
Ka whakaratohia e ngā thermistor me ngā varistor te tiaki nui i te pāmahana nui me te ngaohiko nui. Ka aroturukihia e ngā thermistor te tauwehenga pāmahana kino (NTC) ngā huringa pāmahana i te wā tūturu, ka ārai i te wera nui i roto i ngā kōwae mana-tiketike. Ka tere te mimiti o ngā varistor i ngā ngaohiko ngaru, ka tiaki i ngā maramara me ngā papa ara iahiko mai i ngā pikinga ngaohiko me ngā kino hiko.
Me whai whakaaro te kōwhiringa wāhanga ki te rahi o te kete, te mahi hiko, te manawanui ki te taiao, me ngā paerewa pono pēnei i te AEC-Q200 mō ngā tono motuka. Mā ngā kete iti (0402, 0201, 01005) ka taea te whakanui ake i te kiato PCB, ko ngā wāhanga pakari ia ka mau tonu te pumau i raro i te pāmahana teitei, te haumākū, me te wiri.
I te whanaketanga tonu o ngā hikohiko ki te whakaitiiti, te auau teitei, me te mohio, ka noho tonu te mahi a ngā ātete maramara, ngā inductors, ngā tātari, me ngā wāhanga tiaki hei whakatau i te hoahoa pūnaha. Ko te whiriwhiri i ngā wāhanga SMT kounga teitei, rite tonu te mea nui ki te whakapai ake i te pono o te hua, te whakaiti i ngā reiti rahunga, me te whakarei ake i te whakataetae whānui.
